CanCollide is set to true. Anchored parts that collide with my character's parts are passable. Unanchoring them fixes this as well as switching to the default character or any of the models in the RigBuilder. When I jump with the character the parts are also not passable. Any suggestions on how to fix this?
Edit: Solved my own problem. No clue why, but when I set the RigType of the Humanoid from R6 to R15, the bug stopped. Weird.
Check that you have a humanoid root part. If you do, make sure ONLY the HumanoidRootPart is anchored and can collide is set to true, nothing else. That's the only thing I think could be the problem.. if this doesn't fix it then it's most likely a bug. Do you have any custom scripts running in the StarterCharacter? That might be an issue depending on if the variables you've set match everything correctly. Hope I could help, good luck.
