Problem with DR rendering

[Srieg]

Hey, can anyone tell me why this strange error happens? I have all my assets with right UNC paths, so that should not be the problem. It seems it has to do something with lights, but again Hdri are on network drive set with the correct UNC path, and IES lights are just the standart that ships with vray, no custom files for webs or something. Is this kind of error common with DR rendering?

Ive had renderings come out like that recently and it was due to plugins being wrong versions or missing completely on the slaves.

Yes, that is a good point, make sure that all your versions of V-Ray, 3DS Max and all other plugins are the same on all render slaves.
Aslo you can use "Transfer missing assets" in DR options, you can add VRayDRBucket render element to see which of your machines
produce different buckets.

Try to make a DR with simple scene and if the problem is only with this one, you can send it to us /support@chaosgroup.com/ for investigation, let us know the
version of V-Ray and what additional plugins do you have.

Its funny, I had all the plugins and soft with versions on all of the computers and it rendered as mentioned. But then I updated ForestPro on all of the computers to a newer version, and now it works fine.

There might be some discrepancies in the plugin versions of the Forest Pack which could cause such behavior.
We are glad to hear that after the update everything worked file now.
What was the previous installed version of Forest Pack, and what is the updated one?

[Srieg]

Now it is version 4.3.7, and the one I had was probably 4.3.4 or 4.3.6, I don't really remember.
But in any case, since this update everything is working fine. Ok, except Vray RT, but that is because I have non supported video card (GeForce GTX 970).

[Svetlozar Draganov]

The latest V-Ray versrion 3.10.03 supports Nvidia Maxwell technology and GeForce GTX 970 should work without any issues.
What is the V-Ray version that you are using?

[Srieg]

Yes, I have 3.10.03 but every time I choose GPU CUDA engine type I get "Vray Standalone has stopped working" error.


A small edit - it seems that in this particular sceene it crashes, otherwise it works. Maybe the sceene to big or something?

[Svetlozar Draganov]

How much memory it is available on the GPU device and how much is occupied during the rendering?
Can you send us a screen-shot of the vray.exe-console when the crash occurs?

Yes, I have 3.10.03 but every time I choose GPU CUDA engine type I get "Vray Standalone has stopped working" error.

I cant remember the how or why but if you have an HDRI in the environment background try disabling that and see if that works
