Changing model scale make model animation broken

I got a this model and when I script it to move, the movement is so slippery, the problem is from “model scale”

it’s too low to make it move strongly so I changed back to 1, but the problem is the animation only work if it set to old model scale value, how to make the animation works at 1 model scale?

Before changing the model scale (0.012)

After changed to 1

Things that are scaled down greatly suffer from becoming slippery. To fix this you would want to change the size within the software you use before you export it to roblox. I dont know why it does that at low scales but this has worked for me in the past.

thankyou :)) ill try to fix it
