Hello again Tom! As always I feel that I should thank you for such an amazing asset! We seem to be having an issue with the projectors in our game not behaving correctly with tessellation enabled. Currently we are using tessellation with "height&normal from texture" enabled. We've narrowed it down to this feature. On the surface (pun intended) it appears that the projector is drawing on the actual terrain data and when RTP draws the terrain using the normal map texture it sometimes displays above the actual terrain (expected behavior). If that is in fact what is occurring, or if you believe something else is occurring, would you happen to have any idea as to how to make the projector work with tessellation enabled? Also, please note that the terrain pictured is purposefully bumpy. It doesn't occur on flat terrain, so we noticed it on ramps and the edges of cliffs the worst.
