Hey guys, I have hunted through every thread about ptex normal displacement on the forum and I can’t find any information on how to make it work like a normal UV’d displacement would. I suspect this may have something to do with the troubles you’re having with the vector displacement and subdivisio…

I don’t see anything wrong with the settings. Can you send me your Maya scene and Ptex file to vasil.velikov@chaosgroup.com ? The Mudbox file will also be useful.

I’m trying to do the same as you Hellobard, while with uvs & exr works perfect, still any lucky for my side. Neither with Displacements nor with Vector Displacements. I too have researched the forum, tested all options in many combinations, nothing…

I sent my files to Vasil yesterday, so hopefully he can have a look at it and determine what’s wrong with my workflow :slight_smile: As you can see from my picture, V-Ray obviously reads the ptex displacement file, I think it’s just a matter of getting it to subdivide the mesh according to the valu…

Hellobard, yesterday I get ptex displacement perfectly working, with Vray 2.0 not nightly, under Win 7 x64. Just apply a Vray Mtl material, in the shading group, add ptex in the displacement slot, turn off filtering. Usually the “default” mesh configuration is “normal displacement”, activate it if …

That’s interesting that you got it working! I did essentially exactly the same. Tried it with two different tests/meshes. Did you add any subdividing on your mesh or did it work without it?

Nope, tried it again, exporting the base mesh and the ptex once more, but to no avail. Still the exact same result :confused: Maybe this is an issue with the nightlies?

I have experienced a ptex error with the nightlies. It is essentially broken at the moment. However if you revert to the latest stable version ptex works just fine. But then you loose the Vray Framebuffer, which does not work with the stable version. At least not the one i have installed now. It’s 1…

Yes, there seems to be some problem there, we are looking into it… Best regards, Vlado

Thank you for the scene, hellobard. I’ve tested it with the latest nightly(the one from revision 16905) and I managed to render your scene succesfully. Here’s what I did. At first, I tried to use the ptex file that you sent me. And I got exactly the same results as yours. I don’t know why, maybe th…
