Projection + lighting?

Hi guys…

thx for ur all tips through the site.

however, these days i got a problem.

as u know the “Projected Texture.fx”, and it can give us

the view of position-independent texture.

but, when i try to project 4 texture(which are bottom(white), left(green), right(blue), back(red)) trough one
project, they are too bright to affect the other plane.

so i want to control the light like phongpoint or phongdirection…

how can i do that? does anyone has solution or advice?

plz help me T^T;
