Not sure what happens but I import a FBX to use that geometry in Ragdoll (I did it a lot of times without problem ) but now when selecting replace mesh the manipulator becomes a sphere. The meshes haven’t history by the way
Any idea what’s happening?
Without seeing what the mesh looks like it’s hard to say what the problem may be. But things to look out for is a mesh where each face is disconnected. Try selecting a face or vertex and translate it; if it comes apart then that could be an issue. Ragdoll would try and make a collision shape out of each face.
You can try and play with some of these settings to see if anything changes.
Markus, it was my fault. I realized I exported that geometry without thickness ( I created it using Blender and later exported to FBX) That mesh didn’t have thickness because the solidify modifier wasn’t exported.
Since I hide that geometry when replacing I didn´t see the problem, sorry. I have made you waste time
