Hi. I have a little problem with a matrix and a directional light.
I have a normal matrix textured and randomized, correctly configured to accept ambient light, fog, etc. And I have a directional light over that matrix, pointing at the center of it, active, colored, etc...
However, the matrix always renders very dark, like if no light was created near its surface.
If you can help me, please do, and I'll give my thanks!

PS: The light simulates the Sun in a RTS game, and the matrix is the terrain

Unfortunately the matrix is not effected by scene lighting until you set the normals. Setting the normals tells the matrix what direction the light is hitting it from, you give each tile a value from -1 to 1 based upon the direction along each axis.

It's sucky I know, but actually some good effects can be achieved with it.
