In: Atomic Nodes
The Emboss node performs a simple 2D shading based on 2 inputs, simulating light falling on a surface with height and depth variation.
Both inputs are mandatory to achieve an output from this node.
The Emboss 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.
- Input: Color/Grayscale
Mandatory input that provides the base, unshaded colors. See it as a sort of diffuse or basecolor texture.
- Intensity Input: Grayscale
Mandatory grayscale input that represents the heightmap used to calculate lighting on the surface. Black is low and white is high.
- Intensity1: 0-10
Sets the intensity of the of the "height" map and thus the strength of the lighting effect
- Light Angle: 0-360
Sets the angle at which the light is simulated
- Highlight Color:
Sets the color of areas facing towards the light angle.
- Shadow Color:
Sets the color of areas facing away from the light angle.
Examples below use a brick wall and single shape as Intensity Input. The first Input is just a solid red color.
