Can't raycast on Character Controller?

I have no idea why it doesn't work with the character controller's collider, but have you considered manually running the collision methods when you raycast? The Raycast will return the hit info, which includes the object, so you can try manually running the OnCollisionEnter etc.

Do you have other colliders, attached to your character or it's children? If so the raycast might be hitting them. Use Debug.Log, to see what the hit is, when the ray shoud be hitting the character... Have you added your character to specific layer?

I noticed something interesting. The capsule collider I couldn't see from the Character Controller, but when I change the radius and height values to be those of the characters BEFORE I scaled them, then I can see the capsule surrounding the character. Is that what you are supposed to do with a Character Collider?

tr_mp (OP): Colliders try to size themselves around the object, and resize with you. But as you rescale x,y,z, the collider can get confused and be too small or large. So, YES, you are supposed to always check/adjust collider values so they look good.

Collider "auto-sizing" is merely helpful, and is in no way official or special.

I went to the mesh of my character, and looked under "Skinned $$anonymous$$esh Renderer" and found something about bounds, so I plugged the height and radius from their into the controller, but the capsule collider still isn't aligned correctly with the character. Am I supposed to just put in random values until looks about right? Or is there a way I can be more exact about this?

Sizing colliders has always been an art. Adjust the radius and height yourself. The only rule is it should "feel right" during play.

Play other 3D games; rub against bushes and walls. A good collider often skips some parts, but covers some blank space.

Raycasts are semi-advanced, so maybe save them until you have all the easy stuff down.

Well I guess I can do that for the character models, but I am also using a vehicle model. It seems the Character Controller does not like it when the radius is larger then the height, and the collider goes from being a capsule to a sphere. This is creating some funky properties with the vehicle, and I've needed to position the huge sphere collider fairly high in the air, just so its radius will equal the size of the vehicle. I'm guessing I should use another controller, but I don't see a Vehicle Controller..
