I've recently installed ProRender (v. 2.4.11) and enabled it in Blender 2.83.0. The Viewport rendering works perfectly, but I'm having an annoying issue when rendering a frame:
2. But when it's done, the whole render screen turns gray
Here are my specs:
DO you have any compositing nodes? try turnig it off if so
I tried deleting all compotision nodes from Shading, and rerendering, but it sill turns gray by the end.
Delete things from the scene and upload the file so that devs can have a look
I had same Issue. In my case, this only happened when RPR Denoiser is used with 'filter type' set to 'machine learning'.
