fatal error rendering the scene after upgrade to 2.4

[jasonhuang1115]

Hi,

I upgraded to 2.4 after seeing the release news and tested it with a scene. The rendering kept failing with a fatal error. Seems the error came from Rendering region, but I was not doing a region render nor did I enable region render in the Maya render view or VFB?

I hide some of meshes and the scene render just fine. As I unhide meshes, and I then start getting the fatal error thing. Could this have to do with tile textures (<UVTILE>) and PTEX textures both being used in the scene for different meshes? Just my wild guess...

Ok, as soon as I hide meshes with PTEX textures assigned, the scene start rendering normally.

Here is my setting for the PTEX texture node. This is the setting I used when using VRay 2.30.01 and the scene renders normally.

ps. Maya 2013 SP2, V-Ray 2.40.1, WIN 7

[t.petrov]

Can you post a simple scene that can be used to reproduce the problem?
Also what maya version are you using?

[jasonhuang1115]

Thanks petrov. I am using Maya 2013 SP2 x64 on Win 7. I did a test again and I am positive that as hiding the PTEX associated meshes, the scene render normally as I was using VRay 2.30.1 under the same environment. Let me see if I can associate the PTEX texture to a simple mesh to reproduce the issue.

[ivaylo.ivanov]

Any news on that? Were you able to make a scene for us?

[jasonhuang1115]

I found that the issue seems having to do with the mesh in the scene as I put the same PTEX texture on a newly created sphere and the scene rendered just fine. I'll check to see if it's ok to email a simplified scene for you to examine.

Thanks.

[t.petrov]

PTEX files are tied to the mesh they are painted on, so I don't think sending the PTEX with arbitrary mesh will be helpful.

[ivaylo.ivanov]

Yep, maybe you can try to delete part of the original mesh.
