+There are several settings that control how detail is used.
|
|
|
+
|
|
|
+Mask: The detail mask is a black and white image used to control where the
|
|
|
+blending takes place on a texture. White is for the detail textures, Black
|
|
|
+is for the regular material textures, different shades of gray are for
|
|
|
+partial blending of the material textures and detail textures.
|
|
|
+
|
|
|
+Blend Mode: These four modes control how the textures are blended together.
|
|
|
+
|
|
|
+- Mix: Combines pixel values of both textures. At black, only show the material texture,
|
|
|
+ at white, only show the detail texture. Values of gray create a smooth blend between
|
|
|
+ the two.
|
|
|
+
|
|
|
+- Add: Adds pixel values of one Texture with the other. Unlike mix mode
|
|
|
+ both textures are completely mixed at white parts of a mask and not at gray
|
|
|
+ parts. The original texture is mostly unchanged at black
|
|
|
+
|
|
|
+- Sub: Subtracts pixel values of one texture with the other. The second
|
|
|
+ texture is completely subtracted at white parts of a mask with only a little
|
|
|
+ subtraction in black parts, gray parts being different levels of subtraction
|
|
|
+ based on the exact texture.
|
|
|
+
|
|
|
+- Mul: Multiplies the RGB channel numbers for each pixel from the top texture
|
|
|
+ with the values for the corresponding pixel from the bottom texture.
|
|
|
+
|
|
|
+Albedo: This is where you put an albedo texture you want to blend. If nothing
|
|
|
+is in this slot it will be interpreted as white by default.
|
|
|
+
|
|
|
+Normal: This is where you put a normal texture you want to blend. If nothing is
|
|
|
+in this slot it will be interpreted as a flat normal map. This can still be used
|
|
|
+even if the material does not have normal map enabled.
