Shading that is applied to the edges of a surface relative to where it’s viewed from.

This is similar to the Rim Light feature in a standard Phong MAT.

Using rim shading can result in aliasing issues, since it’s essentially highlighting the areas that are most likely to have aliasing.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Enable	When off, this shading will produce values of 0, meaning no contribution to shading.
Level	Brightness of the shading, which is used as a multiplier for the Color.	Runtime	Baked
Use Color	Whether to produce color or just a brightness value.
Color	Color of the shading.	Runtime	Baked
Use Surface Color	Whether this shading should take into account the surface color attribute on the SDF (if present).	Semi-Baked	Semi-Baked
Enable Shadow	Whether to apply the shadow to the color/level produced by this element.	Baked	Baked
Thickness	Width of the highlight area on the sides.	Runtime	Baked
Blending	Amount of fading between highlighted and not highlighted areas.	Runtime	Baked
