I saved a few files from Rhino6 as Rhino5 file. To Render it with Vray in Rhino5. But everytime I start the Rendering it just get’s all black. Tried it with same Settings on another Rhino5 file and it worked.
When I copy the whole geometry in a new Rhino5 file everything is working. Somebody know what happens there? Is there a way to fix this?
