#Diffuse color buffer, modified with gl_FragData[1].rgb, will hold the unshaded color of the fragment, usually modulating the material diffuse+ambient color with the texture map. Diffuse color from environment mapping should also go here. | #Diffuse color buffer, modified with gl_FragData[1].rgb, will hold the unshaded color of the fragment, usually modulating the material diffuse+ambient color with the texture map.

In anyway, don't use gl_FragColor as it is incompatible with MRT (Multi Render Target) and would affect the four last buffers with the same value. In that case, the model will glow (emission buffer initialized) and parts will disappear at certain view angles because normals are not initialized properly. | |||
