RPR material not rendering in preview I've installed and activated ProRender engine, but materials won't render even in a basic setup. However from the materials side pane it looks like it can render it correctly.
I'm running macOS Big Sur on MacBook Pro 2020 (cpu only).
Edit: rendering of the image works... only render preview does not
Many thanks for your help!
Got it! Disabling Viewport Denoising and Upscaling in Render Properties → Sampling → Viewport &amp; Preview Sampling does the trick. ¯\_(ツ)_/¯
