Still new to Unreal but have been using C4D for quite some time. I am aware of the “no smoothing group information” and “Face material index inconsistency” issues that show up in the message log when importing an fbx from Cinema. For the most part my model has imported with correct smoothing, except for a small area that seems to not have it at all. Attached are screens of the issue in Unreal and what my model looks like in C4D
I have my export settings from C4D using the 2014 fbx format. My phong tag has Angle Limit and Use Edge Breaks checked, with the Angle being 88°.
When I import into Unreal I am just using the Import Normals method (Normals and Tangents seems to destroy the smoothing) with my fbx Export Compatibility set to 2014 in my preferences.
If anyone has an idea for a work around let me know!
