Hi!
maru and borisquezadaa, thank you very much for your detailed information. Actually i had installed a UNC Path, but something seemed to be wrong so that i resetup everything exactly like you discribed and voila, the proxies are all rendering fine! Thanks for that.
But now there happened different strange things, you can see it in the picture attached.
The renders starts fine, but than after 2 minutes or so there appears something like a white stripe in the image. I dont know why.
When i hide the proxies it still appears in the render. But only again in distributed rendering mode. When i render it just with my workstation everything works fine.
You have an idea for that?
I am going to despair little by little :(
