Thank you for your time. I really appreciate it.
I am setting the scale to 16 because my model is too small after export. Yes, I can do it in U4, no problem with that. But… when I leave the scale and set it to 1, there is another problem. Coordinate system during export (or import?) is not taken into consideration, no matter how I set axes during export. I still got the import warning from U4 that “FBX bind pose ‘BIND_POSES’ is invalid. It will be ignored.”. This must be related somehow but I don’t know how to fix it yet.
This exporter must be broken. I will try to hack it a little bit, but I do not know FBX internals. Think it’s time to learn
