OpenCL GI Problem

[zumpitu]

Hello All !

Im starting to work whit your distribution fo Blender, very nice !!!

I found some problems using the OpenCL... it works fine but I cant use Global Illumination..it not work ! And when I use OpenCl the Render have no End....

Also I don´t find the way to use the same Frame Buffer for multiple render, I will have always a new one

Knks !!

Realtime engine has different GI realization. So it works, but not the same way. But afair you have to enable "global inllum" option in render settings.

Also I don´t find the way to use the same Frame Buffer for multiple render, I will have always a new one

Realtime render update is in progress and not yet in the public script: http://www.youtube.com/watch?v=H4s4K707ur4

Great ! Do You know were I can find some specific documentation abaut it?

Yep... I´m sorry I post in a wrong way the question. I I meant to normal/all renderings ... If I render 2 time the scene I always have 2 Render Buffer and I like to "reuse" the first whitout have many windows.

Thanks for the video, it looks very goog, I hope we can have it quikly

Hallo Again !

Ok... I See GI works on OpenCl but I found this problem, i dont know if dippend to the DemoVersion o is like e bug..

If i try to have an Hdr in the enviroment i have no render...

if try to ad a Sky texture from the Sun Light I have only blak "sky"

Also I tryed the "old way"... Ad a sphere whit Light material and hdr texture for color..but not work

Im sad about because i have a really really fast render on my sistem... and I need to have Hdr for the reflection,maby also for the light sistem.

i found the way to save the renders in to the Framebuffer

Building OpenCL trace program for device NVIDIA CUDA_GeForce GTX 560...

It builds a trace program - could take 10-15 minutes - this will happen once and then runs smoothly.

Re: OpenCL GI Problem

Hahaha, I have a little patience, ok!

Thanks again!

Re: OpenCL GI Problem

Well, now with Vray Standalone, I'm testing again with Vray RT but the process takes more than an hour and I have to stop it.
Any advice?

I can't control any vray itself related stuff may be chaosgroup support can help you.
