Oups, I forgot that...
Something I started yesterday night, which is far to be done. I continue it a little bit today while eating my sandwich
Between the gun, you can see some sculpted patterns :
Because of the lack of information, I did some sculpting researches: I created a simple base mesh in Amapi and imported it in ZBrush (1), I did a very fast rough sculpting to search the shape and the design of this pattern, I did a retopology (3- sandwich and retopology are not good friends and then, I have a base mesh, close to what I want, ready to be sculpted again.
I can use the projection, but I don't want to use the first sculpting, it was just a test, something simple to find what I wanted to do. I will start over, to have something a lot more clean. I think my new mesh will have enough polygons to give a good result with a normal map when the sculpting will be done, or to be use with a displacement.
This workflow can seem weird, but like that, I can focus only on my recherches and then, I can focus only on the technic, and not both at the same time, losing what I have in mind
Later, the shape done.
