How export constant keys? I have recorder cutscene where the characters and the camera are teleported depending on the camera frame using constant keys.
When exporting to unity, the keys become linear and the movement between teleportation becomes noticeable, how do I solve this? (Simplify doesn't help)
To reproduce the problem, you need to record the constant key, export fbx, import it, and it will become linear (in the span of one frame).

baked :
If when exporting your asset you let the bake animation enabled and the sampling rate on 1, then it should put keys on each frame of your animations, removing any interpolation and negating the effects of key type change.
I forgot to mention, Blender's FBX exporter does a keyframe cleanup in its baking, which you might want to remove by setting the &quot;simplify&quot; to 0.
