At last, I started the development of GMP4. (1 is Original, 2 is Insect maker, and 3 is Plants Generator)
This time, 'Inheritance of property' is a big theme. I'm thinking 'How to make act a face as a cell of life'. An our cell divide many times, but the divide cell has the same property. So I got an idea to use 'material' for it. The material is able to apply for each faces. If it would be divided, same material would be applied for divided faces. Same on extruded faces. And it's selectable. I think it's a good idea to use materials.
