actually i noticed that a fly's body tends to have a blue tint as you move towards the edges and a yellow specular highlight - so the sampler info node was used to try to create that effect. i added a yellow tinted color map for the spec map, but i think i'm going to get rid of that as it doesn't seem to be working.Originally posted by AikoWorld
if i understand it correctly your samplerinfo is created for the edges of you geometry creating like a reversed occlusion, but instead of a static collor you can add an image to it
Or a more relevant file is a ramp.
Well i dont know if thats what you tried to create.
Cool shading network!
