Material - Basic glass

Two pass material

First pass draws the surface, second affects Alfa and Z-buffer to keep correct visibility and shadow casting.

First RVMAT

renderFlags[] = { NoAlphaWrite };
nextPass = ofp2\Data\glass_2pass.rvmat;

Second RVMAT (sklo-pass2.rvmat)

renderFlags[] = { NoColorWrite };

diffuse[] = { 1, 1, 1, 1 };
forcedDiffuse[] = { 0, 0, 0, 0 };
emmisive[] = { 0, 0, 0, 1 };
specular[] = { 0, 0, 0, 0 };
specularPower = 0;
