Is 3ds max Biped compatible with the FBX exporter By Unity ? I mean, FBX is exported to Biped and connected to FBX exporter. To fix animation again, I have to create a key animation with biped. But, after the process, the biped is gone, and only the FBX Geo and Bone are left. I think the same is true of other custom rigs. Then, isn't the FBX exporter provided by Unity for animation? Just BG or modeling? If you are animator or Rigger using 'FBX exporter', then, please help me out.
