@ Oxynary It's not that difficult. Chamfer some edges, re-route some of the loops, and a dash of pentagon. If you can get away with it, you should consider making it a separate piece. It would be much faster to model and unwrap, and just deal with in general. Hmmm...I probably shouldn't have those narrow loops running…
Ups.. black magic of the internet.. now the two images appeared in the first post of this and the one i tried again (where was no "reaction".. also..) Anyway: in blender any edge can be "greased".. meaning the influence of the subdivision is lowered.. so a fully greased model would be visually not subdivided at all.. For…
If equadistance (or even approx., just makes it not 100% "square"), just loop each corner edges for each shell, marquee deselect edges on corner, bridge.
