[edit] Description
Velvet or Rim Light shader
[edit] Usage
- Create a base texture with an alpha channel. The alpha channel should be a horizontal ramp, light to the left and dark to the right.
- Assign it to the texture property of any material using this shader.
- Tweak alpha channel to achieve desired effect
