Hello, a little update on this project.
I have a working prototype of a prodecural skin made with geometry nodes. The thing is running well, it is not as heavy as it seems. The procedural approach has my preference on this project. I really like how the skin is following the topology underneath, small or big polygons giving a credible effect.
A big part of it is the Dual Mesh node that gives this organic pattern feeling, like cells. Many thanks to his Italian author (I forgot his name)
The final design is not done yet.
No real shading for now, because I am working on a 3D print version first rather than a 3D render. These weird colors are just here to make boolean selections easier.
It makes it looks like a Zentradi spaceship from Macross!
