Types Of Maps
Diffuse - A diffuse map is the most is the most common type of texture you will find. Diffuse is a raw colour channel for a 3d model. Specular - This map defines the shininess, or how much the light the surface reflects. This map is grey scale, white being the most reflective and black the most absorbent. Gloss - A gloss map helps define the roughness of a surface. The darker areas would be rough, the lighter areas would be smoother. This helps create surface detail when coupled with a specular map. Albedo/Base colour - An albedo/ base colour map should normally be devoid of shadows and highlights, this map should be just the base colour. An albedo is more commonly known as a diffuse map. The big difference is when used in PBR work flow, there is a lack of directional light or ambient occlusion. Roughness - A roughness map and gloss map that are similar, though roughness is what would be found in PBR. Dark areas of the texture will have a...
