Advanced Member Grimmy Posted July 27, 2020 Advanced Member Report Share Posted July 27, 2020 My model looks fine in Blender and Cinema4D. When I bring it into 3dCoat it has missing faces. How can I solve this? Image and .obj file attached 3dCoat 4.9.53 AssetFactor_01.obj Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 27, 2020 Report Share Posted July 27, 2020 Hi - Opening the model on another app, i found all normals inverted. Please check attached file. - nGons, avoid work with ngons, quadrangulate o triangulate all faces will help. - Inner geometry floating. If it is not visible delete it. Hope it help AssetFactor_01.obj AssetFactor_02_quads.obj Quote Link to comment Share on other sites More sharing options...
Advanced Member kenmo Posted July 27, 2020 Advanced Member Report Share Posted July 27, 2020 This happens to me quite a bit when I bring a model from Silo3D into 3D Coat. And ALL the time it is reversed normals. Did you check for flipped normals? Blender has an option to change all the normals to face outward or inward.

Advanced Member Grimmy Posted July 27, 2020 Author Advanced Member Report Share Posted July 27, 2020 Okay Thanks guys. Yes I saw the faces were inverted but I didn't think this in itself would cause the issue as I simply checked the flip normals on import option. However I never saw those internal faces so maybe it was those causing the issue. Thanks for the direction! Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 28, 2020 Report Share Posted July 28, 2020 If you need to see the backface of polys, turn off Backface Culling. Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 28, 2020 Report Share Posted July 28, 2020 Note: Prior to version 4.9.55 a bug prevent 3DC to import ngons polys for PPP. Ngons were deleted at import. This issue was fixed. Quote Link to comment Share on other sites More sharing options...
