I work on improving my last big mesh object. It looks most fine in edit mode. But i have this error.
So something is wrong, checked filenames. checked for dot's in names. But i keep having this error in edit and publish mode. On top of that in publish mode 2 materials get invisible. and the are visible in edit mode ! The building have 26 materials. No baked textures. the are not efficient and the quality would be drop below 0.
The only thing that could be wrong is something with edges, last thing i can test right now. Not see what else could be wrong.
