Scenario:
Two files, same model. One is game mesh, one is high-poly. I want a normal map.
Importing High-poly into Game-poly
The high-polys don't render at all. I just get black. I put lights and fiddle about with the render settings, but the high-polys are just completely ignored.
Importing Game-poly into High-poly
The game-poly mesh renders, but none of the modifiers are saved, which includes the Unwrap UV, so rendering results in a nice box of red for error.
Can someone please tell me what's going on?
Lucky
Addendum: I would like to say that this is model-specific. I've imported multiple other models into the scenes without any problems of any description.
