NPC Animal MoveTo: + Auto-Rotate

I’ve have made a few animals of varying sizes and rigged them to a fairly low standard using Rig Edit+ Simple, but they work and thats what matters.

I am trying to create a new Polar Bear, but cannot get it to Auto Rotate when issuing a MoveTo.
Yes, I can create an HRP + Torso + Humanoid and get that to move satisfactorily including AutoRotate. As soon as I weld the Polar Bear body mesh to the HRP, it stops auto rotating and just slides across the floor like a piece of soap.

I’ve attached an file with examples of the minimal requirements for NPC, a working mesh bear and the annoying slidey nemesis. Keen to get him working cos he will make a great addition to the game.

Any help would be greatly appreciated.

I’ve acually never seen this behavior before, but weirdly enough, setting all the instances’ Massless property to true (except for HumanoidRootPart) somehow made the polar bear rotate towards where it’s moving…?

More interesting is that whenever I would set HumanoidRootPart’s Massless property to true aswell, it would stop auto-rotating again? This is some really odd behavior, but here is the modified polar bear model:

I have a suspicion that AutoRotate’s force has some sort of… max force? Kinda like body movers, and your polar bear meshes are like… too heavy for it somehow – or atleast have too much mass? You can read into the Massless property’s documentation if you want to read up more information.

Thank you so much for looking. I have spent waaay too much time trying to fix this. He is a much happier bear now. Thanks once again

Ah. So you are the person who made Physics Based Spring too. Nice
