Hi.
I know nothing at all about procedural mesh generation and such, but I’d like to achieve a decal system similar to this one. What things should I learn in order to create this kind of decal system inside Unity?
If you’re just interested in having decals for your game, you might consider just using the “Decal System” on the Asset Store. It’s free, and I’ve used in in several of my projects. It works very well.
