hi? When will it be updated to Blender 4.0?

[difaandailisi]

The plug-in cannot be imported, and a traceback window pops up

Same question for me i would love to use this.

Hi @difaandailisi @mobilex1122

Work for blender 4.0 under process. AMD should release as soon as possible.

The 3.6.10 development build also fixes RX 6400 support.

Hi guys,

Please, use build: https://github.com/GPUOpen-LibrariesAndSDKs/RadeonProRenderBlenderAddon/releases/tag/v3.6.10

This is release candidate.

While the add-on gets imported, it generates this traceback when trying to enable it. Tested with a Radeon RX550 running with the 22.Q4 Pro Drivers. I also tested with the Adrenalin 22.14 drivers and the same error shows up:

@BrunoDSL ContextCreate returned error "ShaderCompilationError".

Unfortunately, AMD RX550 architecture is not supported by HIP -> ProRender SDK -> blender addon.

It is possible to force old OpenCL hw acceleration mechanism in Blender addon in settings:

Settings: Debug -> Use OpenCL.

Please, be aware that OpenCL backend is NOT recommend and only and only for debug purposes.

That's not possible to do because you don't have access to those options if the plugin is not enabled. This traceback appears when enabling the plugin.

This is a bit confusing, since ProRender is supposedly compatible with every RX card as per their system requirements. And it used to work in earlier versions since I did a bug report on it. Would be possible to modify version 3.5 to work with Blender 4.0?

This is a bit confusing, since ProRender is supposedly compatible with every RX card as per their system requirements.

It looks like documentation may be slightly outdated and give misunderstand. For today, GCN architecture in "support mode" (https://www.anandtech.com/show/21126/amd-reduces-ongoing-driver-support-for-polaris-and-vega-gpus).

It means only critical bug-fixes or security fixes for GCN based GPU's .

[BrunoDSL]

It seems to still work with Blender 3.6 LTS using version 3.5 of the plugin. Version 3.6 started using HIP instead of OpenCL apparently, though only for RPR Final
