AMD ProRender installed but not working I just installed AMD's ProRender and I'm trying to experiment with it and see if I like it.  Using Blender 2.8 on Windows 10.

Here's a scene I made, previewed in Cycles:



Here's the drop down for the Render engines, seems like ProRender is there.  And I didn't have any errors or warnings while installing it or the materials library.


But when I select the ProRender and either hit "render image" or just chance the viewport mode to rendered.... nothing happens.  Like so:


In fact, the objects kinda disappeared.  When I hit "render image" the picture never shows up at all.  I never touched any of the default ProRender settings on the right there.

Any ideas?
For those looking at this later, per the comment section:  the nodes I had used in Cycles were causing trouble.  When I open a new default scene ProRender worked.
