So far im having a blast with Genetica 4's 3d import features, however there are some things i would love to have as well:
When importing an obj file that has materials assigned to groups, it would be great to have the groups in Genetica as well (So you can assign specific textures to those groups, like metal to metal parts, rubber for rubber groups etc).
The AO render pipeline seems a tad slow, but that is probably my gpu.
If Genetica were able to "optimise" uv's (arrange the uv parts so more texture space is used) that would be awesome too, but that might have little to do with being a texture program, and more with being a modelling program.)
Here is an early model im working on in groboto, and it can export material zones, but in Genetica that is of no use as for now.
