Cycles Rendering - "Device" option is not there

[bill2reg]

When I select "Cycles Render" the render panel does change, and also the materials panel etc. But when I click the render (camera icon) I don't have an option to select the render device (CPU or GPU). There are two options, "Display" 'and "Feature Set". The "Feature Set" has two options - "Supported" and "Experimental". But in a tutorial I saw, there were two options under Render - "Display" and "Device". I'm using 2.62.0 with windows 7 64-bit and an ATI Radeon 1GB HD5570 graphics card.

If I remember correctly those options dissapeared in 2.61... but I cant be certain.

Hai guys, i have a same problem.

I'm using Blender2.64 with windows 7 64-bit and an ATI Mobility™ Radeon® HD 5145, 1G DDR3 VRAM


Please help me to resolve this problem.

Just a guess, but I would be surprised if ATI Mobility anything did GPU rendering.

Did you install the OpenCL stuff needed to support it?

[King_Moving]

actually I'm not so knowledgeable about OpenCL.

but, can you tell me what should I install it. :hope:

ATI MOBILITY RADEON can not do GPU rendering?

[stiv]

I am far from being an authority on this subject but...

The whole point of GPU rendering is to use the awesome power of a modern graphics processor for rendering.

The point of mobility processors (and laptops in general) is to skimp and save on battery power, not to be rendering powerhouses.

In order to use GPU rendering, you need to install either the CUDA or OpenCL extra bits, depending on your processor.

CUDA is better supported in Blender (and in general)

All of the above are generalizations.

Hello,

Does anybody know if / when the ATI GPUs will work with Blender?

Thanks!

Kelly

Blender 2.65a
Win 7 64-bit, 8 GB RAM, i7 8 core 860 @ 2.8 GHz
1-GB ATI Radeon HD 5700 Series
Up to date ATI drivers installed

In Photoshop CS6, the Advanced Graphics Processor Settings is allowed to utilize the GPU, but in Blender, I see no options under the Blender User Preferences, System tab, Compute Device.

Did you install the OpenCL stuff?

That's a great question! ... I have no idea.

Is there a particular KB article that you might point me to read more about this stuff? I'd be very thankful if you could.

Photoshop's indicators makes me think that (at least some) OpenCL stuff is already installed; see screen capture below, and in addition to the settings in PS having been ticked, the behavior in the Blur Gallery works fine along with Liquify, etc. which is why it seems OpenCL is working.

But if any OpenCL stuff is installed (as PS implies), it was not by my overtly and particularly doing so.

The Catalyst Control Center version is up to date which reports that the drivers are likewise up to date - see below.

Thanks again Stiv for your help.

Kelly

@ stiv - Well, after combing through the past several months of related threads on this subject, I'm guessing there isn't a comprehensive KB article dealing with this stuff yet - please correct me if I'm wrong

The other bit of information salient to this discussion appears to be tied to OpenCL

developed by the Khronos Group with no new updates from them since November 2011.

While developers may find much needed information in the "OpenCL™ Zone" this newbie to the Blenderlands found nothing pertinent from AMD's site.

More yet to read / study over at blenderartists.org, including:
http://blenderartists.org/forum/showthr ... ners/page4
however, the referenced archived article has me a bit anxious.

FWIW and specifically in regard to SivaS's thread: "A good news for AMD/ATI Graphic cards owners" - Blender 2.65a,

Code: Select all

#define __KERNEL_SHADING__

is already un-commented (no double // in front of line) at line 43 in

Code: Select all

C:\Program Files\Blender Foundation\Blender\2.65\scripts\addons\cycles\kernel\kernel_types.h

That thread really should be closed!

Greetings King,

Yes, thank you for showing what I had said earlier, namely that the remarking out of that call as originally referred to in SivaS's thread, had already been removed by the time 2.65a came along. Who knows how much sooner, but that is moot.

Thanks again.
