b3c8b483d8 Move fbx to Blender keyframe time conversion into blen_store_keyframes 
Add faster blen_store_keyframes_multi for when multiple fcurves have the same keyframe times.

f91d576625 initial implementation (and revert only using the first anim curve per channel) 2023-08-31 04:56:24 +01:00

2ffbeeb8e7 Use only the first anim curve per property channel 
The FBX SDK documentation specifies that the FBX animation system's default implementation only uses the first curve assigned to a channel. Additional curves per channel are supported by the FBX specification, but the handling of these extra curves is considered the responsibility of the application that created them.

This patch changes animation imports to discard extra animation curves for each property channel after the first curve has been found. When this has occurred, a warning is printed to the system console.
