Character stuck in Tpose

This is likely happening due to Humanoid animations not being supported in Luna at the moment. Check if your animation type is indeed set as Humanoid by looking at the imported model asset's import settings under the Rig tab. (Example of this below)

Alternatively this could be due to an Avatar controller being used for the animation, as this is not supported in Luna.

Possible solution:

• Avatar / Humanoid animations need to be baked to generic animations, full steps on doing so can be found here.
