Custom Model doing 'drifts'

Okay, so, I’ve imported a custom rat model, and inserted a pathfinding script, it’s all good, but, the rat is ‘drifting’, I’ve tried increasing hipheight, increasing rootpart density and decreasing other stuff, but it’s still sliding.

Did you check the weight of your rat? I believe it’s too light

This happens will small humanoid rigs.

The rat has 4300g in mass, I don’t know if that’s the problem

Well, in the video, he is double the player’s width, and the same in height
