Member SimonB Posted August 13, 2016 Member Report Share Posted August 13, 2016 3dCoat 4.7.06 After importing model with only "Treat materials as separate textures" checkbox set on , everything seems to be ok, but ambient occlusion can be baked only for the first UDIM square. All the other (outside main UV area) don't bake http://take.ms/fi3PX it's strange because Curvature is baking fine http://take.ms/ISAhF Quote Link to comment Share on other sites More sharing options...
carrots Posted August 13, 2016 Report Share Posted August 13, 2016 You need to enable "Import Tiles as UV Sets" option in the import dialog Quote Link to comment Share on other sites More sharing options...
Member SimonB Posted August 13, 2016 Author Member Report Share Posted August 13, 2016 I've already tried this option and it works ok, but it replaces initial surface materials names with UDIM numbers. When you export textures you got names like objectname_1001_texturename, objectname_1002_texturename etc. Sometimes textures could be tweaked by hand by other person and it's not intuitive which texture goes where. Ofcourse I could add surface materials names before udim numbers by hand but it seems counterproductive. is there a reason why curvature bakes ok and AO not?

carrots Posted August 15, 2016 Report Share Posted August 15, 2016 UDIM numbering need for your render. I have no idea why curvature bakes ok and AO not Can you send me the .3b file with a similar result for the test? Quote Link to comment Share on other sites More sharing options...
