Why does this rig have ice physics w/o any scripts?

When I put this rig in StarterPlayer as a StarterCharacter, the player is using the model as expected but randomly it has ice physics (so it walks slightly slippery/there is momentum) and when you shiftlock, the character smoothly turns. I have no idea why. There are no scripts.

Here’s a video demonstrating:

And here’s the rig if you want to put it in studio to look at it yourself:

Only real problem if most bodypart have properties > Massless = True

I suggest turn off it will fixed

from little mean massless just 0 weight

That was it! Thanks a lot! Funny how making all the parts massless makes it like this.

I also forgot how to make replies into solutions :confused:

Hehe, yeah, as @Hest_z said, this probably should have been in the Building Support or Game Design Support forums.
