Oh, well I am not that experienced, trust me.
It's just that here we are talking about a plugin that works in a certain way. Then you come with a mesh done in Artisan, and ask for advice to apply textures in quads, which clearly you have none in your ship.
You can apply textures with Thru paint and also SketchUV even if you don't have quads, but it is easier to apply textures if you have your mesh divided into portions, top, sides, wings, details etc.
Sketchup was/is primary used for architecture, that's why the texturing is so ancient. To paint a couple of flat walls is easy, but to apply a texture to an organic shape exactly as you want is nearly impossible.
That's why is good to have a nice simple geometry with some texture applied to it, then after you subdivide that, the texture will readjust, although not perfect.
I usually don't apply textures of this kind, it's out of my hand. Just here and there a couple of tires which are symmetrical and easy to apply.
I am using box mapping and planar mapping most of the time when the textures are quite repetitive, but when they are not, you must cut the surface in parts to map them individually.
There is a guy one the warehouse who makes just simple square objects, but he applies some good textures and everything looks stunning, maybe you should take a look at his models. https://3dwarehouse.sketchup.com/model.html?id=c4420d36292ee89874499a543081c292 scifilicious by the nickname
Yes, I already felt sorry after I replied the first time. Sorry for being a bit harsh !
Hope you can make it after all !
