Searched for a good deffered lightning/shading shader tutorial or article (a tutorial whould be preferable) but can't fint anything good out there. The thing i want to do is, to render the pixel into a texture (this to store the depth) , and then in the second pass of the shader i want to do my deffered lightning on those pixels that need it (refer to depthtexture). Im using OpenGL and GLSL, whould be awsome if anyone have any suggestions of article or tut, about this whole topic. Tnx for your answers , and keep the good code up !
