Is there a "outer surface" operation in Blender?

Postby learning » Sun Sep 20, 2015 10:29 pm

I know I'd be better off asking this in some Blender-oriented community, but MH is the only one I know that's at least sorta relevant. So there goes… Suppose I have an object in blender that is made out of several joined objects, some of which may intersect others or be to some degree contained inside one another, i.e., long story short, inside it is a mess. What I want is to get only the outer surface all those intertwining objects form, i.e. the set of outer points of all those objects. Is there a way to easily obtain this in Blender?

Best I can come up with is joining all the objects and then shrinkwrapping something atop of the result.

What you are proposing is a massive retopology; Blender is okay at this, but 3d coat was designed to solve these kinds of problems. :geek:

You can download a trial version and see how it works; the forums are also quite good.

Wow, that's actually not a bad idea!

Why don't you use the boolian modifier, set to union?

Tried that, but it produces weird meshes that are all but impossible to further work with. Boolean in general is useful if it's the last thing you do to the mesh, which may not be always the case.
