I would have suggested the same andreseloy. But I think Thebest12, as he stated ‘any magic button - click and it turns into a shell’, which I believe, if you are looking for that “one click option”, is the unify button. Do it at a low resolution and then reactivate Zmodeler. Voila. But it’s not all within Zmodeler as he wanted - soz.
Thebest12, just out of interest, is there a reason why you are just trying to stay within Zmodeler? Sounds like you might be making hard work for yourself fella to accomplish tasks, instead of using the full range of tools in conjunction with each other. The only thing I can think of is you are comparing with other 3d packages. If that’s the case then, even they are not a one click options. You still have to mess around with sliders/buttons etc for thickness, depth, segments, inner and outer amounts, override material IDs etc (Shell modifier - 3ds max). Anyway good luck in finding that one click button, I hope you find it.
Just had a brainstorm: hmmm wonder if a macro/script could be written for it :idea:
Has the zmodeler tools been setup for macro/script usage? Not delved into this bit of Zmodeler yet.
