Not sure what you mean by that, but as far as I can tell, edge loops affect curvature uppon smoothing the mesh. Add them close to the edge and that edge is going to be sharp. If you add loop further from egde, its going to be more curvy..
Ok thanks again. but i got another short question. on the model i want to add some bolts on rounded surfaces. i tryed it with bending these bolts but it gives me no good result. any idea how to add bolts and detail stuff on curved surfaces?
so, this time i used max. so just create an helix and add lots of curves, both radius need to be the same. you can turn on, render in viewport, and add like 7 segments for the helix. convert to poly. add a ffd 2*2*2 and select the 4right control points and pull them down. then you can, scale the helix down on all axis, and…
Have you tried physics + cloth simulation in blender ? Find out what material that is. And drop the pieces on top of a plane that simulates clothes (with restriction) too see if it gives you the shape?) if you want to sculpt it. You need an understanding where the folds crease and how it happens. Imagine putting in one…
Delete your support loops/unecessary geometry so that you can definite the shape and silhouette much easier. Then from that point, you can turbosmooth by smoothing groups to add geometry, or add manual support loops and go from there. The top triangular detail is well done :)
