vaColor

in vec4 vaColor;

Valid Programs: gbuffers_*.vsh, shadow.vsh

The vertex color attribute, equivalent to gl_Color from the compatibility profile.

The color attribute is often used to apply tints to colored blocks such as leaves, grass, water, etc. It also contains the vanilla ambient occlusion and, if enabled, the old lighting.

Enabling separateAo will move the ambient occlusion from the rgb components of vaColor to the a component, which can be applied later like this:

vec3 color = vaColor.rgb * vaColor.a;
