- To use the Projector/Light and Projector/Shadow shaders properly:
- Cookie texture:
- 1. Make sure texture wrap mode is set to "Clamp"
- 2. Turn on "Border Mipmaps" option in import settings
- 3. Use uncompressed texture format
- 4. Projector/Shadow also requires alpha channel to be present (typically Alpha from Grayscale option is ok)
- Falloff texture (if present):
- 1. Data needs to be in alpha channel, so typically Alpha8 texture format
- 2. Make sure texture wrap mode is set to "Clamp"
- 3. Make sure leftmost pixel column is black; and "Border mipmaps" import setting is on.
