Where do I put gloss maps in unity?
For the Unity 5 standard shader you have to go into Photshop or Gimp and insert the gloss map into the alpha channel of the specular map.
What is a gloss map?
The gloss map defines the smoothness, reflectivity and tightness of specular highlights. For metals, the shader doesn’t control specular color – the specular texture map does. Specular color is physically based.
What is specular map in unity?
Specular Properties See in Glossary. Additionally, the alpha channel of the main texture acts as a Specular Map (sometimes called “gloss map”), defining which areas of the object are more reflective than others. A well-made Specular Map can make a huge difference in impressing the player.
How do you apply gloss and Spec maps on one?
Gloss maps should be inverted and plugged into the roughness input of glossy shaders. Specular maps should be plugged into either a mix node factor input or into a glossy shader’s color input (if the material is a metal do the later and do the former if it isn’t).
What are gloss maps and what do they represent?
Dramatization aside, gloss maps are grayscale representations of the specular widths of a material or grouping of materials. Find your texture map you wish to apply your gloss map to, and separate out how many different materials you have there.
Where to plug specular maps into glossy shader?
Specular maps should be plugged into either a mix node factor input or into a glossy shader’s color input (if the material is a metal do the later and do the former if it isn’t). Height maps can be plugged into the displacement input of your material output, fed through a bump node or used in a displacement modifier.
Where to plug in gloss map in UdK shader?
If you’re confused as to where to plug the gloss map in within the UDK shader network, it’s the ‘Specular Power’ input as shown below: One last thing I feel is a good practice to get into when working with specular and gloss maps is channel packing.
