Hello,
I think it is a problem with mapping. When using Rhino 5 I had a material library and it worked fine. Now, with the same materials there is the problem. The Rhino renderer takes the right material assignement, as at the picture:
See the mapping set as WCS box style. Then, the same rendered with Flamingo looks completely different:
So, I have changed the material properties, and I have set mapping like at the picture (Rhino renderer):
You can see, these two look completely the same, at least the textures look the same - mapping, positioning and the rest. So, I think there is an error when Flamingo takes material settings. And as @jacquesmm said, there is only a workaround, to set mapping for each individual surface… I still hope it can be improved.
edit: all the pictures are taken from the Rhino 6 and the nXt 5.5, the latest releases.
Regards, Jaro
