Ok, I´m sure the UV unwrapping / baking will fix this. I did this test rather fast and didn´t unwrap / bake or anything, just to see what happened.
The question remains though if Indigo RT / Blendigo is up to production standards. I know after following Blender closely for a couple of years now that (for better or worse) it is kind of in a constant development (if you want the latest tools/adddons etc), and keeping track of which plugins, exporters etc that works for the moment is time consuming. I might jump of that train.
I´m also looking at Modo 501 which contains all tools in a single package at a reasonable price. But then again, some Indigo renders are really
I wish that Indigo was more open to other standard formats, like .obj or so.
Maxwell is producing really great renders, but is slow (haven´t tested it myself yet).
Vray - there we might have a connection from Blender, but it feels kind of shaky.
Anyway, thanks for the directions so far.
