VRay RT GPU glossy refraction and fog color

[Jiri.Matys]

Hi,

I tested VRay RT GPU and little bit confused, because glossy refraction and fog color doesnt works. In VRay RT CPU works as usually. Is it normal?

Yes; we still have some work to do on these; I hope they will be there around next week.

Best regards,

Have a big problem with GPU version. Almost everytime its stops render right after image shows up (I think with low kpaths for gtx 295), 3ds max running, but it didnt continue rendering and wrong pixels shows all over the monitor, really bad errors, but i can close vray and 3ds max, but errors still there until I restart (never happened this error). It look like GPU related, but never happened with any GPU raytracers, games etc!!!

You can try some of the tips here: http://www.spot3d.com/vray/help/rt10...gpu.htm#errors (where it says common OpenCL errors).

Look at the link and its all right.
When make a simple scene, CPU and GPU works fine. When load some complex scene, CPU works and GPU stop working and error pixels shows up, as I said previously or V-Ray shut down. Maybe If you look at the scene, maybe there is something bad for GPU, dont know. Test 3 complex scenes and no one is function under GPU, under CPU all works fine.

And question number two, will Area shadow option under VRayShadows and procedural maps works in the future?

And question number three, I have GTX 295 but it seems not so speed up to me (both core is working), dont know how many times GTX 295 should be faster then Core 2 Quad 2.83 GHz in a simple scene.

Haloooo, anyone?

If you can get me one of these scenes to vlado@chaosgroup.com, it will certainly be useful; other than that, is the CPU version only running fine?

OK, I will send you one. CPU version running fine in these scenes.

Did You look at it?

[vlado]

Yes, both scenes render fine on my gtx 480; testing on the 295 now...

Ok, thanks.
I will send You one more scene, on GPU wrong texturing appears. And some other errors.
