UVW Texture wth is that?

After lot's of failure I finally started making kind of decent 3D models. Best practice was imagine what you want first then look that thing on google get inspiration. Then start modelling whatever comes into your mind. Somehow you'll start liking your models. At least I did, and my wife and kids as well. So now I've few models now what? It's just pale plain gray objects time to PAINT them. In past I've only dragged and dropped so called materials into models. But this time it is not a floor or ceiling/sofa so I had to understand UVW mapping? thingie. So followed few tutorials and got unwrapped model on image file, now I have to draw texture/material thingie on photoshop. It's super challenging for me. But yeah eventually you might can do kind of decent texture. For now it's damn hard since I don't have any inspirational soul whatever the hell is that. Using same method that I used on modelling. Gotta google few, imagine, find what you've imagined apply that logic to your texture. Hopefully I'll get it done.
