Animations not aligning properly when working with rthro avatars

[treebee63]

When playing certain animations on NPCs with certain packages, joint welds behave weird.

This is what I expect to see.

This is what I actually see in-game:

The animation varies depending on which package you’re running, and it seems like it’s only accurate on rigs of similar structure.

Something interesting:
If I were to copy those exact animations and play it on the broken test rig…

It lines up perfectly, and uploading it to the game causes it to work perfectly on that model.

Does anyone know a way to fix this? It seems like the roblox animator plugin can figure out the joints, but the in-game character animator cannot.

If anyone needs testing files, I have attached them below.

After doing some digging, it turns out pipelining a moon animator export into a model via AnimSaves, then uploading it from the roblox animator will cause this issue. The solution is to simply upload the KeyframeSequence object directly to Roblox. After that, everything is peachy. Don’t make the same mistake folks!
