an example file is on the way (per wetransfer).
Right, the wrong look is caused by the fresnel function. This problem isn’t so important, since I use Enscape for the render output. But a solution could be nice. I set the fresnel value 1.5 at Rhino 5, so, I don’t understand why Rhino ignore it. For me the fresnel option looks like an option to much since the IOR should do the job.
But very important for me is to find a way to handle the materials of (linked) blocks. I wrote some words at the wetransfer message, but maybe it’s interesting for other users, so here a quote:
A first step for a help would be if I could edit materials of linked blocks. An other helpful step would be, if I could merge all materials with the same name from different blocks. For example my train is full of blocks with a wall plastic and I’m looking for a way to edit the wall color without to open dozen of linked blocks. Unfortunately I can embed the blocks, the file size would be a few GB.
I edit the “polster 1KL” material at two linked seat blocks and updated them. Now I see older versions of the material too, the red and the blue material was a temporary test only and can’t be find at the linked blocks anymore (orphans?). Also _purge doesn’t clean it.
I would be glad if we could find a stable solution. At the moment I have no pressure by the project, the hot phase will start later.
