Hello,
I’ve exported a .vrscene file with Vray-RT 3.50.04 under 3Ds Max using the .vrscene exporter.
When I try to render it with Vray Standalone (latest 34003) I’m getting an error that Vray is not able to create a filestream (vrimg file as output):
[VFBCore::SetRegion] Error writing render region to raw image file. | [RIFile::WTRegion] Error writing channel buffer. | [RIFile::WTChan] No file stream
This is the command I’m using:
“C:\Program Files\Chaos Group\V-Ray\Standalone for x64\bin\x64\vc11\vray.exe” -sceneFile=“Z:\Dropbox\assets\GEN_noise-caddata\mdl\GEN_noise-caddata_CamA_all.vrscene” -imgFile=“Z:\Dropbox\assets\GEN_noise-caddata\out\img\test\a.vrimg” -rtEngine=5 -region=none
A few more infos:
The CMD is started “As Administrator”.
I’ve tried multiple variations of the command, also with but the error stays the same as soon as I want to render .vrimg files.
I’ve tried rebooting, since I thought it might be a file pointer orphaned. Didn’t work.
I’ve tried writing to a different locatoin (even C:\temp\), still no luck.
I’ve tried multiple different .vrscene files, even very simple ones.
I’ve tried using all different -rtengine types, CPU and CUDA option both lead to the same result.
Another weird thing:
Now as soon as I try to write another file format like .exr or .jpg while knowing that it will not support render channels (lighting, gi etc.) I’m getting another error:
error: Unhandled exception: Unhandled exception c0000005; last marker is at line 3610, file “./src/vrayrenderer.cpp”: Preparing camera sampler
It outputs a crash dump which you can find here:

I’ve also uploaded you the scene file with all assets (luckily it’s very small). You can find the max file in here as well as the .vrscene file.

Another thing:
I’ve seen that the latest vray standalone thats available for download is rather old and when I try to render something it gives me
some warnings about unknown properties relating to the newer features from 3.5 (option_glossy_fresnel, option_use_roughness etc.).
Is there maybe a newer standalone version that supports these features?
Any help is much appreciated! 
thanks!
