Hey, I was wondering if it is possible to integrate somehow within my game based on Unity Engine?

I want to have a character creator.

I guess I can export a lot of pre made sprites and then put them up together in my engine, but maybe there are an easier way ? Is it at all within terms of use ?

Hello mate, there's no way to integrate 8D directly into your game as a character creator, but you can of course - as you mentioned - generate a lot of premade sprites and import those into your game.

This is doable and allowed!
