AMD's (ProRender) Plugin for Blender

Fatesailor · November 22, 2020, 1:08pm

This is quite understandable. I just wanted to mention the problem as a feedback.

This would be great indeed! ProRender is already a powerful renderer, so it will be good to be enriched with such features.

More tech details of hardware accelerated ray tracing in RPR 2

@bsavery hey what’s the plan with blender rpr and macOS on their SoC since it only supports metal api.

The current macs don’t have an ams gpu - while it looks that the m2 or higher SoC might get back some eGPU or even connection inside a pc box like the rumored MacPro.

bsavery · November 29, 2020, 5:55pm

So RPR is using the Metal API. As far as I know the blender plugin should work with the official build of blender with the latest M1 Apple computers. (which would run via rosetta)

However I imagine the plugin we publish would not work with @skw 's experimental ARM build. If / when that becomes blender official we would look at supporting it.

Can’t enable on Big Sur.

Get the build from https://github.com/GPUOpen-LibrariesAndSDKs/RadeonProRenderBlenderAddon/releases/tag/v3.0.1

@bsavery Nothing on cryptomatte yet ?

bsavery · December 21, 2020, 4:53pm

https://github.com/GPUOpen-LibrariesAndSDKs/RadeonProRenderBlenderAddon/releases/tag/v3.0.13 this development build includes cryptomatte aovs.

When will be available working Apple M1 version (GPU)?

bsavery · December 21, 2020, 7:44pm

Do you have a M1 chip to test this on? Have you tried it? But it SHOULD work if you have an x86 build of blender.

If you’re seeing something different, please report a bug on github.

anon80315389 · December 21, 2020, 8:11pm

This is what I get in x86 build:

In Apple Silicon build I can’t enable RPR addon:

bsavery · December 21, 2020, 11:06pm

Doesn’t surprise me on the apple build. An ARM executable can’t load dylibs compiled for x86. Which is basically what that error is saying.

The artifacts in the other version are strange, but again we haven’t tested it (you know since it’s not our GPU). But I’ll see if we can do something.

anon80315389 · December 28, 2020, 10:50am

Great. Thanks.

bsavery · January 23, 2021, 2:08am

Some good updates since we last talked!

Added Cryptomatte support
Adaptive sampling
Adaptive viewport resolution (for viewport speed)
OpenColorIO support
Animation random noise seed

What is the definition of Backscatter as used in the uber shader?

Does this help?

SO I have a “fun” case.

Blender 2.92 or 2.83 - Prorender latest 3.0…

CPU 1950x, 64GBs, Windows 10
GPUs - RX 6900x + Vega 56 + Vega 56. - 20.12.1 offical drivers

6900 renders great, no issues

Any vega (or combination of setups) starts causing corruption. red/white checker pattern.

For the first 1/2 of the render, all GPU’s render perfectly. then corruption starts.

Tried OCCT GPU and GPU memory testing, no issues. Gamining, no issues.

I’ll try the latest beta drivers from AMD, but do wonder why there are no certified drivers since December 2020…

I can test any config if needed,

Grzesiek · March 16, 2021, 10:04pm

I’ll give the latest beta builds in a short bit, but I’m getting same wierd effect as yfile in windows10 on the official build. This only happens when i mix GPU’s together (Vega + Navi2) If I just render on Navi2, no issues, render on Vega, not as many issues.

Will report if latest beta 3.0.31 fixed the wierd “tile” spiral issue.

Grzesiek · March 16, 2021, 10:33pm

Generally (so far and more testing to do) all 3 GPU’s are rendering together.

However there is a “instance/scale” issue.

First image is the cycles render whiel the second in ProRender. One of the modules (square block of the ship that is instanced from another file) is rotated in Pro, but not Cycles, and one module is scaled up 10 fold though not visible in viewport or Cycles render.

And interesting that it seems to be just the two modules, all others modules or other instanced files are OK.

Hi all! We just released some new builds for your pleasure including the following enhancements:

Support for AMD Radeon™ RX 6700 XT graphics cards has been added.
Cryptomatte AOVs make it easy to filter objects by name or material when using compositors that support Cryptomatte (including the Blender Cryptomatte compositor node)
A 16-bit Machine Learning Denoiser option is now available to provide for less memory usage and greater speed.
The speed and responsiveness of the viewport render has been vastly improved under RPR 2.0:
An option for using Machine Learning Denoising and Upscaling the viewport render is enabled under the Viewport Settings. We now render faster at ½ resolution and use the Machine Learning Upscaler to enhance the resolution;
Changing the properties tabs no longer restarts the viewport render;
Stopping the viewport render is now much faster;
Various other fixes to speed up the viewport render have been added.
An often requested feature, Box mapping in the Image Texture node, is now supported!
Support for Principled Hair BSDF has been added.
UV Lookup nodes and math nodes now work in the High, Medium, Low modes.

And a lot more fixes as well as these. Check them out at https://github.com/GPUOpen-LibrariesAndSDKs/RadeonProRenderBlenderAddon/releases/tag/v3.1.0
