In advance: I’m a super n00b in rendering / visual content creation.
I would like to know some tricks for adding randomly generated moss or cracks or snow (something to make my walls a bit more interesting) to my 2D game. It shouldn’t be a very expensive material because it will run in mobile.
Ideally it should not use any lights at all … the game is a bit cartoonish looking and it does not need very reallistic look. So I would like to just randomly put some green pixels here and there for the moss, following some random pattern.
Initially I thought about using a normal map to give it the shape of the moss but it would imply to use static lightning at least (all my materials are unlit right now). In any case I have no clue about how filter the moss through a random pattern (i dont want my walls cluttered by moss either).
The cracks should follow also a random pattern.
As you can see I’m a complete beguinner here, I have tried to google around but I don’t know how to search for what I’m looking. So I will appreciate any advice / link / tip for starting doing things like this.
Thanks in advance,
