Projectors, Decals, ......

Hello,

I'm creating a tactic rpg and i want to draw textures over the terrain (only where i can walk), but using projectors are very expensive because it redraw the mesh lots of times. There is a way to specify when to make a draw call (I want to draw the mesh after the last projector affected the mesh)? Or should i forget the projectors and go play with the meshes?;



Each red square is drawn by a projector(Ubber slow). The actual terrain has 512 triangles and with the projectors it has 51.7k triangles;

Obs: The terrain isn't flat and its just a test.

 

Bump

no idea?
