Meshy Animation prepares your uploaded 3D character with an automatic skeleton, then applies a motion from Meshy animation library by action ID. Set character height in meters for correct scale. Pick walk, run, combat, and gesture clips from the full catalog, then optionally change frame rate to 24, 25, 30, or 60 fps or extract the armature. Works best on clean biped humanoid GLBs. Ideal for game NPC locomotion, trailer characters, social 3D posts, and quick motion tests on Scenario-generated models.
