Using Wings3D for tattoos

[micheus]

It is a shame Wings3D can not / is not meant to do what I am looking for.

It's not a shame.
Most the 3D apps are generalists and are all in one nowadays by including modeling, sculpt, animations and paint tools.
By definition: "Wings 3D is an advanced subdivision modeler that is both powerful and easy to use" - It's focused on modeling. It doesn't have a tons of options as the big apps, but it does well what it was designed for. Also, it's interesting to see that some commands/options for modeling that it has just recently has been added to these big apps.

I also would like to have an option to paint and - at least - pose characters inside Wings3D, but that isn't going to happens soon. There is only to programmers working on it using their sparse time (bjorng and dgud). They has been working in the last two years to improve performance, bring a more modern UI and introduce better shaders options (we got PBR viewing).

Everything else depends someone to write a plugin to add new stuff, which is rare - unfortunately.

I hope you can solve your problem easily with Blender.
