It is so frustrating how the rig doesn’t get the same results in the fbx file when using some constraints for better poses. It just keeps you completely locked, not letting you put the animated character rig that is meant to be supported by game engines.
I don’t really get why the Stretch To constraint is not completely supported by the fbx exporter yet.
It also appears that the Tracking constraints are not entirely supported yet, and that results in inaccurate poses for some bones that use a tracking constraint.
This really needs to become a bug fix in one of the next 2.8x versions.
Also I’m not trying to demand a bug fix here. What I’m really doing is I am giving the tips for the fbx importer/exporter addon that needs to be improved.
Hi @Maker26, what @NahuelBelich is trying to say is that FBX is a closed format, with the original SDK closed. In Blender this has been reverse-engineered, with all shortcomings that go with reverse-engineering.
No, I said that for Blender the FBX (binary) format was reverse-engineered - the official SDK for the format cannot be used since it has an incompatible license.
