Raycasting against a specific collider and/or a list of colliders?

I want to raycast against a specific single mesh collider but I can't seem to find an appropriate physics method that would do that. My collider is disabled (for unrelated reasons) and should stay this way, but I want to perform a raycast against it and it only. Is there a function that does that? If not, how I would go about doing such a thing?

And no, I can't assign this collider to a bespoke layer. In my use-case this won't do the trick. (Unless I can assign a collider to a specific layer at runtime and then remove it from that layer?)

 

3D? Yes: https://docs.unity3d.com/ScriptReference/Collider.Raycast.html

2D? No: You have to raycast and then select from the results.

 

Thank you kind sir.

Collider.Raycast() is the correct answer here, but you can assign a Collider to a specific layer at runtime by setting the collider.gameObject.layer to whatever number (0-31) that you want and then setting it back to the original layer later.
