Problem With My T-Rex Physics

Hi all, im having trouble creating a ragdoll for my T-Rex, when i create a physics asset from my model i get an error “bone size is to small” i scaled up my model and now it is very big but still the same problem so i lowered minimum bone size and it creates one but when im trying to move the physics body’s they vanish, any help would be appreciated …

Make sure that the bodies are not overlapping + make sure to post a picture of how it looks like :slight_smile:

Sorry, hear are some pictures

i add a body,

if i try moving it using the translate tool it vanishes, and i press F to focus on it and its gone so i have to undo to get it back

And if i simulate this happens
