First, add a Vector > Normal Map node. A sort of recap for dummies:-Specular maps come from and old texturing workflow (Yess we can still use it). However, keep in mind that matte absorbs light while gloss reflects it. Sharpness: Glossy finishes enhance the perception of sharpness, while matte finishes offer a softer, less pronounced look. It can make the difference between a mirror or brushed steel. Less prone to fingerprints and smudges. That's what glossy/reflectivity maps are for: determining how much of the light is reflected (how much intensity it has after bounce). In a glossy map, white areas are glossy and black areas are rough. The difference between FOO and FOO16 is that a FOO map uses 8 bit data, which is often enough, where a FOO16 map uses 16 bits. -Now we use a PBR (Physically-Based Rendering) workflow So there are to Workflows: Metalness Workflow (PBR new) Specular Workflow (Old) Nov 22, 2021 · Reflection map usually goes into Reflection Color and the Glossiness usually goes into Roughness but only when it has been inverted or reversed because glossiness is the opposite of roughness, so just invert it. A value of 0. The reflection map can be omitted - As far as I can tell, it's responsible for some kind of specular tint, which blender usually provides VIA a metallic factor - so if the . Basically, the gloss map is the intensity of the spec map. Using PBR Maps is one of the easiest ways to add realism to your renderings!
