I’ve seen a few other people having similar issues but wasn’t able to find a lot of information specific to R15 which uses the FBX 2013.3 format. This should be compatible with Unreal 4’s fbx format. I keep having issues saying that “The imported scene has no initial binding position (Bind Pose) for the skin.” I also keep getting the "Warning: No smoothing group information was found in this FBX scene. Please make sure to enable the ‘Export Smoothing Groups’ option in the FBX Exporter plugin before exporting the file. Problem is, I don’t have that option in my Cinema 4D fbx export options. I’m also pretty sure I’ve set the initial binding pose in Cinema. But none of this seems to be coming over.
I went looking around the web, found out that Smoothing Groups are are the same as the Phong tag in Cinema, I also found elsewhere a table of acceptable phone angles that a user suggested the prior version of UDK played nicely with. Here is what I found, http://www.reddit.com/r/Cinema4D/comments/1qj0ri/cinema_4d_to_unreal_engine_3_tips_tricks/
I’m just not having any luck here getting a simple test animation over into Unity. I’ll post screenshots of my dialogue screens below. Thanks in advance.
