Forward Plus Additional Lights - Custom Lighting Models

Uploaded March 2025 | Updated September 2026, 2 weeks ago

In episode 7 of the series, we added multiple light support to our custom lighting model - but it only worked in Unity's Forward render path. Today we add Forward Plus support - so we can use either render path and our multiple lights will still work.

Take a look at the playlist for the whole series:
