) So I'm quite new to Blender and I'm lost. I have a 3D stl file with a lot of details (high amount of vertices). I want to UV unwrap it to paint it precisely on photoshop. Now, I've tried a few methods for UV unwrapping and none of them work properly:
-smart UV unwrap: my model gets so deconstructed that I can't tell what I'm painting on (eyes, ears etc.)
-creating seams manually: I don't find a way to select multiple edges to form a line: I click on an edge, click shift and click on another edge but the selection just goes from one edge to another, it doesn't combine them, even though I'm on "extend existing selection" mode. So I can't select a line to then convert into a seam.
-creating UV maps with "project from view": I never manage to select al the faces I need. What I do for selecting the front of my character for example, is go to X ray mode, select all then go out of X ray mode, flip the model, and deselect the back with ctrl + click. Despite that,there are holes in my UV map.
What would be the solution to unwrap such a detailed model? A big thank you in advance if you can help!
