Расчет тени от солнца
Фирма, в которой я работаю, в числе прочего, занимается расчетом падения тени от зданий. До сих пор мы расчитывали все в Экселе и строили двухмерку в автокаде. Сейчас хочется делать все в 3d. Возникает вопрос, в какой программе это легче и проще делать? С учетом того, что учитывается только солнечное освещение в конкретной точке земного шара, в конкретное время суток, в конкретную дату?
3D Max вроде справляется, но долго и муторно. К тому же, присутствует разница между расчетной длиной тени (по нашим прошлым расчетам) и тем, что выходит у MAX-а. То ли наша модель расчетов была не верна, то ли MAX считает приблизительно.
Autocad 2009 имеет возможность установить нужное солнце, но тень от солнца у меня не рендерится. Возможно, я что-то делаю не так, т.к. вообще до сих пор работаю в 2002-2005 автокаде и 2009 вызывает у меня «личную неприязнь». Да и вообще, рендерила я из автокада считанные разы, поэтому однозначно не знаю всех возможностей и опций.
SketchUp вроде бы подходит полностью, но до вчерашнего дня я его в глаза не видела, поэтому сомнения.
Возможно, существует какой-то опробованный вариант, а я пытаюсь изобрести велосипед? Что посоветуете?

Sketchup+Podium | Проблемы с рендером
здесь наверняка есть люди, пробовавшие работать с Podium-ом для Sketchup-а. при попытке отрендерить последнюю модель, у меня возникли проблемы. не могу понять, в чем дело. то ли модель сложная, то ли подиум не правильно геометрию обрабатывает. причем отдельно кусок модели еще реально сделать. а целиком - уже никак. никто с таким не сталкивался?

Всем привет!
Столкнулся с проблемой, выполняя видеоурок: не работает VRay 3D mapping VRayDisplacementMod (2D работает). Вроде и карта нормальная, 32 bit. В чем может быть проблема?
P.S. наверное, с самой картой что-то не так - 93 MB весит 0_о
и нет смысла использовать такую тяжелую текстуру, перевидите ее в 8 бит, ну или в 16 если сомневаетесь
Александр, у меня эта опция вообще неактивна - выделял разные файлы. Впрочем, у меня и до этого были проблемы какие-то с путями, или с Configure User Paths, или дело в том, что в пути есть папка с названием на кириллице. Может, мне просто в explorer открыть эту папку с текстурами, и кинуть поверх этой карты в Mat. Editor, а потом перетащить на кнопку текстуры в разделе Textmap
Кинул в тот слот из эксплорера другую карту. Теперь, если увеличить значение "Amount", там хоть что-то происходит, но не то, что нужно все равно. В туториале у него при Amount = 1.5 вот как красиво получается
Александр, Но чувак в туториале не меняет поверхность, кидает на этот Editable Poly модификатор VRayDisplacementMod, другую карту, и у него получается, как на картинке
Может кто-нибудь кинуть 32-битную текстуру, которая подойдет для этой задачи (3D mapping)? Может быть, у меня текстуры неподходящие?
Вот эта, что я в последний раз пробовал, мало весит. Не знаю, можно ли кинуть ту 93-х мегабайтную. Сейчас попробую
Александр, там различается на самом деле - 3D mapping в уроке покрасивей выходит, чем 2D. Но вообще да
Ну вот скриншот с урока, где он сравнивает рендеры, полученные двумя способами. Слева - 3D, а справа - 2D mapping. 3d получше будет
Александр, что такое "дисп"? Но вообще я решил проблему: удалил с объекта материал с помощью MAXScript Listener, в Material editor в новом слоте создал VRay Material с этой тяжелой HDRI картой, и применил к объекту. Затем в другом слоте создал VRayHDRI с этой же картой, применил к объекту VRayDisplacementMod, кинул на него ту же карту, и все получилось. Единственное, что в настройках обоих слотов пришлось увеличить Tiling до 12. Я вот думаю, может быть, и проблема была в том, что в текстуре, что была в материале объекта, Tiling был высокий, а у новой карты, которую я кидал на VRayDisplacementMod, он был равен 1. Но уже все равно. все получилось. Извиняюсь за такие мутные вопросы :)
дисп, это сокращенно Displacement)) и когда стоит VRayDisplacementMod, то в Material editor дисп отключается, так что дело было не в этом
This page provides information about the Displacement in V-Ray for SketchUp.
Overview
Displacement mapping is a technique for adding detail to your scene geometry without having to model it first. The concept is very similar to bump mapping. However, bump mapping is a shading effect that only changes the appearance of a surface, while displacement mapping actually modifies the surface.
Вопросы по Скетчапу.
1) Как изменить угол обзора камеры, чтоб больше влезало?
2) Что делать, чтобы облегчить сцену в Скетчапе, или как работать с тяжелыми?
3) Правда ли что сочетание сктчапа и вирея довольно глючная штука, или это мне так везет?

V-Ray for SketchUp Usage
Cloud Rendering and Cloud Credits
Cloud rendering comes with your SketchUp Studio subscription and you will always get the most recent versions of SketchUp and V-Ray for SketchUp in Studio. Currently V-Ray for SketchUp provided with SketchUp Studio will work in SketchUp Pro 2019 or SketchUp Pro 2020.
I see Chaos offers 20 free cloud credits for the trial users. How do I get their free credit offer?
If you’re currently using the SketchUp Pro trial and wish to also try out V-Ray for SketchUp, you’re able to do so with both.
If you’re using V-Ray for SketchUp provided with your SketchUp Studio subscription then you already get 20 credits and you’re not eligible for their trial based credits.
What is the workflow for saving my SketchUp project on Trimble Connect, my V-Ray project with cloud credits, and the fully rendered project ? Where are they get saved, Trimble Connect or Chaos Cloud?
You can upload your SketchUp project to Trimble Connect either directly from inside SketchUp by using the Trimble Connect extension OR by first signing into Trimble Connect and uploading the project directly through it. Connect does not work with Vrayscene. The fully rendered project (via Chaos Cloud) will be hosted in Chaos Cloud and you can then download the assets once the render batch is complete. There is no connection to Trimble Connect.
How many projects can I render with 20 cloud credits?
It depends on the nature and complexity of the scene you are rendering. For example, 10 credits might get you 2 images of a bee and flower, 5 images of a night-time archviz scene, 20 images of an interior, 30 images of a diamond ring or 250 images of a balloon.
Is there a way to estimate the cost of a cloud rendering job?
One way to estimate how many credits you’ll need for a job is to render a test image with your trial credits and note how many credits it consumed. Then expand that cost by what your final job will take in terms of the final resolution, quality, frames, etc.
Can I store my projects in the cloud or I can use it only to process my renderings?
Chaos does not offer cloud storage for files. We recommend that you either save your files to your local machine or store it in the cloud using Trimble Connect. Trimble Business Connect, included with your SketchUp Studio subscription, has unlimited storage for projects.
What happens to any files stored in the cloud if I end my SketchUp subscription?
You will continue to have write access to your project up to the limits allowed by a Trimble Connect Personal subscription. If you’ve exceeded the data storage limit, you still have read access to all your data but will not be able to upload any more files. You’ll always have the option to download your files stored on Trimble Connect.
What happens if I am in the middle of a rendering process and my trial expires?
The trial will expire at midnight, you’ll be able to finish the render, if it was started before the expiration.
What happens to my render if I finish my credits in the middle of a job?
If you run out of credits in the middle of a job, you’ll be unable to finish the job. You will be directed to a Chaos page to purchase more credits.
Can I pause my current rendering process?
Yes, you can pause the rendering process both, whether it’s a Cloud Render or if you’re rendering on your local machine.
Can I save my renders on my machine? How can I share my renders in the cloud with my clients?
Yes and yes. You can save the render (images and or render setting) as vrscene files on your machine. For sharing cloud render outputs like EXR and JPG images can be saved in OneDrive/GDrive and shared with clients from there. More info is here.
How do I purchase more cloud credits?
As a SketchUp Studio subscribe how do I check on the status of my monthly Cloud Credits for V-Ray?
There are several options for checking your available Cloud Credits:
System Configuration
By default V-Ray is set up to run on the CPU of the machine. You'll be able to use the full functionality and there will be no warnings, though performance will not be as great as in a system intended for 3D rendering.
If you decide to switch from using the CPU for rendering to “CUDA” or “RTX” you'll have to select the hardware devices to be used for rendering.
- In CUDA mode - you'll see only your CPU listed and you can select and use it.
- In RTX mode - you'll see no devices listed and you'll not be able to render.
- This means that even if you have a Mac machine you can still render using GPU CUDA, however only the CPU will be used.
- It can only run on NVIDIA RTX GPUs and will utilize the RT (raytrace) cores of these cards.
- Hardware - If the minimum requirements are not met (e.g. old components - no SSE4.2 support (x64) on the CPU) or there is a malfunctioning component;
- Overheating - highly uncommon, but it's a possibility, mainly during rendering;
- Software - In the case of V-Ray 5, if it's a Windows workstation, only Win 8.1 and Win 10 are supported. On macOS, to my knowledge M1 chips are currently emulated, so it should work, but it's not a bad idea to keep it in mind as a potential cause;
- Corrupted installation of either of the softwares;
- Anti-virus/Firewall permissions (unlikely, but still not a bad idea to be kept in mind);
- Leftover files from previous installations;
- Leftover crack file from a pirated SketchUp or V-Ray;
- Incompatible plugins (e.g. two render engines). Very unlikely to cause a crash, but rather a fault in the way the applications function (still, not a bad idea to be checked);
- Corrupted project file;
- Corrupted materials or assets;
- Potentially, assets with high amount of complex groups and materials applied to some groups (we had instances where a couple of "Explode" actions resolved the issue with such an asset);
- Not likely, but perhaps a custom template might have data that's causing a crash;
- Other scene specific reasons.
You still will be able to use the V-Ray GPU render engine but it will run only using the CPU on your device. For more information please read this FAQ Article on Chaos’s website.
How would I know if my machine can operate with the latest version of V-Ray for SketchUp?
You can use the V-Ray Benchmark Tool to measure how well particular hardware will operate with V-Ray and also find out whether the hardware is supported or not. There is even a results page where you can search results shared by other users and compare the result from their tests with those from the others.
When I try to use the default setting of V-Ray and my SketchUp keep crashing, what can I do to prevent this or improve the experience?
This is a broad topic, since a crash could be caused by a diverse set of factors.
Additionally, issues with the OS could potentially cause a crash, or perhaps missing drivers but this is something that cannot be summarized; Aside from the Windows requirements and M1 chips, it was extremely rare to encounter any of the other factors.
It's best to ask if it's happening with a specific project and if it is, to urge the customer to share it through the Extensions > V-Ray > Pack Project function with the Chaos Support.
Acceptable Device Usage
I have V-Ray for SketchUp installed on my work machine, am I allowed to run V-Ray on my personal machine as well? On how many machines am I allowed to authorize V-Ray?
You can install and authorize V-Ray on the same 2 computers where you authorized SketchUp.
If I have a new machine, do I have to remove V-Ray from my old computer before authorizing it on the new computer?
You should always de-authorize SketchUp on your old computer if you plan to move to a new system.
Note, if you’re forced to switch to a new computer without the option to disable your previous device, you can contact SketchUp support via this contact form.
At this time there isn’t a mobile version of SketchUp that supports V-Ray for SketchUp.
Where can I find the End User License Agreement for V-Ray?
You can view the EULA on the Chaos website here.
If I am using V-Ray for SketchUp under a Studio subscription, which Terms of Service (TOS) or End User License Agreement (EULA) is applicable?
All terms are application specific. In this situation both the SketchUp EULA and Chaos TOS apply since both apps are being used.
Trial Questions
V-Ray for Studio can be “borrowed” for offline use for up to 28 days on 1 machine at a time.
For day to day usage the V-Ray license is “auto-borrowed” for 24 hours at a time on all machines that V-Ray license has been authorized. i.e. If you open V-Ray on your personal and work machine both licenses are automatically borrowed for 24 hours on these machines.

Parameters
Enabled – Turns on/off displacement.
Mode/Map – Specifies the mode in which the displacement is rendered:
Normal Displacement – Takes the original surface geometry and subdivides its triangles into smaller sub-triangles which are then displaced.
2D Displacement – Bases the displacement on a texture map that is known in advance. The displaced surface is rendered as a warped height-field based on that texture map. The actual raytracing of the displaced surface is done in texture space, and the result is mapped back into 3D space. The advantage of this method is that it preserves all the details in the displacement map. However, it requires that the object has valid UV coordinates. You cannot use this method for 3D procedural textures or other textures that use object or world coordinates.
Amount – Specifies the amount of displacement. A value of 0.0 means the object appears unchanged. Higher values produce a greater displacement effect. This value can also be negative, in which case the displacement pushes geometry inside the object.
Shift – Specifies a constant which will be added to the displacement map values, effectively shifting the displaced surface up and down along the normals. This value can be either positive or negative. See the Shift example below.
Keep Continuity – When enabled, V-Ray tries to produce a connected surface. Use it when you get splits (usually around sharp edges) in the displaced geometry. See the Keep Continuity example below.
View Dependent – When enabled, the Edge Length parameter determines the maximum length of a sub-triangle edge, in pixels. A value of 1.0, for example, means that the longest edge of the resulting mesh will be about 1 pixel long (when projected on the screen). When disabled, the Edge Length value is the maximum sub-triangle edge length in world units.
Edge Length – Determines the quality of the displacement. The behavior of this parameter depends on the View Dependent parameter above. Note that each triangle of the original mesh is divided into sub-triangles. More sub-triangles mean more detail in the displacement, slower rendering times and more RAM usage. Less sub-triangles mean less detail, faster rendering and less RAM. See the Edge Length example below.
Max Subdivs – Controls the maximum number of sub-triangles generated for every triangle of the original mesh. The maximum number of sub-triangles can be calculated by squaring this value. For example, a value of 256 means that at most 256 x 256 = 65536 sub-triangles will be generated for any given original triangle. It is not a good idea to increase this value much higher than 256. If that's required, it will be better to tessellate the original mesh.
Resolution – Determines the resolution of the displacement texture used by V-Ray. If the texture map is a bitmap, it would be best to match this resolution to the size of the bitmap. For procedural 2d maps, the resolution is determined by the desired quality and detail in the displacement. Note that V-Ray will also automatically generate a normal map based on the displacement map, to compensate for details not captured by the actual displaced surface.
Water Level – Turns on/off water level.
Level Height – Specifies a value below which the geometry will be clipped. See the Height Level example below.
Since putting in a new graphics card i'm having problems with RTX & CUDA rendering with complex and/or high resolution images - particularly when using displacement maps. Basically the software either finishes rendering before it's begun, or it crashes the software completely.
I can still render the same scene on the CPU, but it's time consuming and only seems to handle resolution up to 3-4k.
I am using VRay for SketchUp 4.20.01
The graphics card is an EVGA GeForce RTX 2080 Ti
I am currently waiting for a RAM upgrade (currently 16gb) - I don't know if this will help. One error message I get is this. " failed to create dump file: "(error 183) "
I don't know what the problem is.
I'm not very tech savy so please talk in layman's terms as much as possible.
I really need help with this, trying to find paying work urgently and my hardware / software is letting me down!
There are a couple of reasons why this might be happening:
1. Your GPU drivers might have to be updated.
I believe that the 'Finish' before it starts was sometimes caused by that.
So the first thing I'd do is try updating the drivers to the latest version.
2. If SketchUp crashes all together it might be a crash in V-Ray Core.
To test this we'll need a SketchUp scene to test.
An exported .vrscene might also work.
Just make sure to pack all the necessary assets.
3. This might also be a memory issue (GPU or CPU RAM).
The CPU problems that you've faced sound suspicious.
Keep in mind that even though V-Ray GPU (CUDA and RTX) use your graphics card there are still some calculations done on the CPU.
I'd try removing the C++/CPU from the list of GPU devices first.
Another calculation done on the CPU that might be causing trouble is the Light Cache global illumination.
To test this theory, you can go to Settings/Advanced Panel/Global Illumination and select Brute Force from the Secondary Rays menu.
There is some additional information that might help us figure out what's going on:
- What kind of displacement do you use? Is it Normal or 2D?
Keep in mind that in SketchUp it's relatively easy to go overboard with the amount of displaced surfaces in the scene.
The reason is, the displacement is applied to materials (not objects) and it is sometimes hard to keep track of all the displaced surfaces in the scene.
Does disabling displacement help?
To globally disable the effect use the following option: Settings/ Render Parameters/ Switches/ Displacement.
As a last note I'd suggest you upgrade V-Ray to the latest version - 4.20.02
