Re: Blender Cycles(Opencl on AMD GPUS)

Hello,

we are using LuxRender that tries to work with OpenCL in SLG Path OpenCL variant.

It works very good, but often we hit compilation bugs in OpenCL part of AMD closed source driver.

This bugs, also seen in alternatives like Blender's Cycles OpenCL renderer, are stopping 3-D artists from using Radeon cards in production.

Please, can anyone solve them?

One bug report is here:

Re: Blender Cycles(Opencl on AMD GPUS)

Thank you for working on this problem with high priority, was anything changed in the month of working on it?

LuxRender users (at least - speaking for myself) would happily test any new version (of Linux drivers as for me).

Example scenes in LuxRender that reproduces the problem: http://www.luxrender.net/mantis/view.php?id=1407

In case of questions LuxRender forums are very active and all developers are there.

Re: Blender Cycles(Opencl on AMD GPUS)

Apparently if it works and goes pretty well to start this great but hopefully in future be possible to repair the problem of textures as jpg image - png. I'm testing with Catalyst 13.8 (2) and 2.63 blender well Amd hopefully further improvements.

Al parecer si funciona y anda bastante bien para empezar esta genial aunque esperemos que en futuras se pueda reparar el problema de texturas en imagen como jpg - png. Lo estoy probando con Catalyst 13.8 (2) y con blender 2.63 bien Amd esperemos nuevas mejoras.

Re: Blender Cycles(Opencl on AMD GPUS)

The interesting thing is what happens to me with the graphics not as it is with nvidia cyclos but amd is something wrong but hey I will explain working at 98% constant for over 10 min the graph does not increase its temperature in almost anything from 3 to 5 degrees the other thing is it takes to compile but if we leave it open we can change the color of materials and some other things without problems and is extremely fast the other is more number of passes does not slow down if not otherwise increase the use of ram is reasonable, the bmw gpu now takes 512 passes.

Only works with Blender 2.63 - I can not make it work in any other version.

I'm interested in trying to make it work in 2.68 for hair gait cycles. So any idea hacelo try and walk but also helplessly proves change something in cycles.

He does not go with anyone else tried the 2.64 version and has a prblem of ram and ram fills the 2.61 and 2.62 the white clay out alone. Maybe you can do cyclos ride amd from 2.63.

Solo funciona con Blender 2.63 - no puedo hacerlo andar en ninguna otra version.

Me interesaria hacerlo andar para poder probar en 2.68 para hacer andar pelo en cycles. Asi que alguna idea ya trate de hacelo andar pero sin poder hacer nada igualmente probare cambiar algo en cycles.

No anda con ninguna otra version probé la 2.64 y tiene un prblema de ram y ocupa toda la ram la 2.61 y 2.62 sale solo arcilla blanca.

Talvez se pueda hacer andar cyclos amd desde la 2.63.

Re: Blender Cycles(Opencl on AMD GPUS)

I tested the 13.8 driver (2) 2.68A with blender and it works. But for the GPU rendering is too slow. often slower than my i7.

Re: Blender Cycles(Opencl on AMD GPUS)

You may pass me blender kernel so I can prove it because I tried to use eh or arm and I can not used it also as I am only leaves the 2.63 and nothing more? / / /
Another thing you might go into blenderartist.org?

----------------------

Es posible que me pases el kernel de blender asi lo puedo probar porque lo eh tratado de usar o armar y me es imposible ademas como lo usaste a mi solo me deja el 2.63 y nada mas ?///

Otra cosa es posible que entres en blenderartist.org?

Re: Blender Cycles(Opencl on AMD GPUS)

I'm interested in something like a mixture of bullet http://www.youtube.com/watch?v=hM3wke1mVgE Real-Time Physics but it should be easier not so complex for an average user. Bullet Physics Real - time using blender internal think not? .

A mix sounds interesting?
