I am creating a block game where some of the blocks can have sides which give off light in custom colours.
I have been trying to find a solution to make this work and I think i might have to use a shader. Is that the best way?
Absolutely, use a shader! Use the standard shader for your blocks’ material, then just plug a texture into the emission slot. If you bake your scene, this emission will even cast light on other objects! I have attached a demo cube to show you how its done. [61811-blockdemo.zip|61811]
Let me know if this helps
