Hi, thank you Robert and David for your answers, I really appreciate them.

Robert, you´re right about that in a "normal" illumination, these surfaces should be set to the ambient colour, cause their normals are pendicular with the light direction. But as my scene is an outside static scene, and I don´t want to illuminate a big portion of the scene with the ambient light because it looks "flat", I´m trying to implement some kind of "hemispheric lighting" (from the glsl orange book), but without renouncing to the shadow effect. So, I need this perpendicular surfaces to be lit, and to show the shadows... > Take a look to the Variante Shadow Map algorithm to apply shadow on the > scene. > Instead of use default OpenGL ShadowMap comparaison technique, this algorithm > provide a different way to capture and apply shadow. > This technique take more resource but with a better result. I´ve already tested another filters as PCF, but the results weren´t so good and it consumed a lot of resources. I´ve read about the VSM algorithm, and I was doubting about implementing it. I think that I´m gonna try it, and I´ll let you know the results. Hopefully it will get rid of the problem. Hopefully! Thank you very much guys! PS: Anyway, I´m still curious with the "missing texels" problem. I´ve been investigating about it and I couldn´t get anything... Isn´t there any way to make the RTT camera to set the depth of this texel to the fragments one? Do you have any hint about it? Thanks again.
