If I fire a trace from within a mesh with collision, it collides with the edge of the collision mesh. However I want to ignore if i hit the edge from inside the mesh (an only care if i hit the outside).
The material applied is one-sided, so when inside the mesh, you cannot see the material. Is there a way to detect if the hit surface is visible or not?
A good example of what i want is the Landscape (from beneath it, you can fire a weapon through it, but from above it will collide with the surface).
