I would like to have a square (door shaped) collision trigger. I know that you can make a cube or other asset to be a collision trigger, and you can set alpha to 0 to make it invisible, but it still has collision so you cannot really walk through it, in VR at least, as your hands will get stuck. Is there any way to make a cube (flat, so a rectangle to be precise) so hands can pass though it but also trigger the collision? Thanks!
