renderman in blender under linux problems

Hey there,

I am trying to install the PRman addon along with Renderman under Ubuntu linux but I am having some issues.
Everything runs well, but i dont get any results shwon in IT Renderman window. It shows that it is rendering, but the images stays black. Any ideas on this? I added several lights to my scene added a PRman nodetree but that had no results.

Post some screenshots of your settings, viewport, etc. Is the denoiser enabled? Do you have lights in your scene?

Hey there,

solved it. Just had to hit f12 again and suddenly it worked. Thanks anyway…
