Root Bone moves in animation editor but doesn't move in game

Swapilla · June 2, 2023, 5:42pm

The title is pretty self explanatory, but I’m rigging an armature skinned mesh that is also a morph. I made other ones and they seem to work fine but this one is the only one that I’m facing an issue with. Basically, in blender and the animation editor the hip bone which is the root bone moves. But in game, it doesn’t work for some reason and is fixed throughout the animation but every other body parts moves which makes it look weird.

We are also experiencing this issue in our game: the Root Bone is stiff (unanimated) when the animation is uploaded then played in-game.

As far as I can tell, it seems that this only affects newly uploaded Animations.

I’ve identified the issue (at least, our issue). When the model was imported, it was at a large scale. The modeler scaled down the model (which now applies a new value to the model called “Scale”). Our Animation Editor ignores Model.Scale. Roblox’s animation system has been upgraded to scale the Offsets of animations to the Scale of the Model. To resolve the issue, I simply had to ungroup and regroup the Model (so that scale was at 1). I’m not sure whether this would resolve your issue, though.

As @tbradm said the model was imported, it was at a large scale. To resolve the issue, you need to Ungroup (CTRL + U) and Group (CTRL + G) the Model.
Other issue is that if you want to have an Humanoid in the Model you need to add an Animator inside the Humanoid AND Delete the Animation Controller
