Emboss
Applies an embossing effect by lighting the sides of shapes in an image according to a specified light source direction.
I.e., the node performs a simple 2D shading based on 2 inputs, simulating light falling on a surface with height and depth variation.
This node is not used often for PBR-like projects, but it can serve in certain cases where you want a simple, baked lighting in your texture. Alternatively Emboss With Gloss and Uber Emboss provide a similar, but more extensive functionality.
Parameters
Intensity Float
Adjusts the global intensity of illumination effect. Sets the intensity of the of the “height” map and thus the strength of the lighting effect
Light angle Float
Sets the angle at which the light is simulated. Defines the illumination angle of the embossed image’s highlight
Highlight color Float/Float4
Sets the color of areas facing towards the light angle. Sets the color of the highlight if the input image is color.
Shadow color Float/Float4
Sets the color of areas facing away from the light angle. Sets the color of the shadowed regions of the embossed image.
Input connectors
Input Grayscale/Color PRIMARY
Provides the base, unshaded colors. See it as a sort of diffuse or basecolor texture.
Intensity input Grayscale
Represents the heightmap used to calculate lighting on the surface. Black is low and white is high.
Output connectors
Output Grayscale/Color
