[HELP!] - Skinned Rig Model seems to mess up when moving the Rig

I have a problem with skinned rigging models. When I import a skinned rig to roblox studio, the mesh of the model messes up when I move the rig in Roblox Studio. But when the model is in blender the rig works perfectly without messing up the mesh.

In Roblox Studio:

In Blender:

If anyone knows the solution, please reply.
Thanks

Ill leave here the file if someone wants to check

Roblox’s rigging stuff is kinda problematic at times and questions about rigging usually go unanswered.

Sucks, but figured I’d just let you know.

Do you know any way to get replied with this kind of stuff?

I still need help, so please reply

I did some tests with your model, and it seems to be a problem of Weight.
You will need to weight paint correctly your parts.

Try to watch videos on Weight Paints, and I’m sure that you will find the answer !

( I’m not strong enough in weight paint, but when I added or removed some weight paint I add different results with less or no more deforming ^^ )

Yes, but in blender the weight paints are alright

let me check one second, ill if im wrong

Here is a video of me moving the rig in blender

No they are not, try to reduce the weight from the left leg for example.
You’ll see it’s better, so you need to do all the weight paint correctly on all part.

Could it be a problem of roblox studio interpretating the weight paints?

These are the weight paints

They were made with automatic weights and data transfer.
If I reduce the amount of weight paint the movement looks weird.

If you know the answer please reply

I hope someone knows how to fix this

there’s a limit of 4 weight groups for a single vertex in roblox studio, you probably have some vertices affected by more than 4 groups.
