I have a sign that requires UV mapping. The curved parts have many faces. How do we deal with UV in this situation?
smart unwrap would probably work well.
By cleaning up the mesh first. There’s no way you need them triangles there, most of them can easily be turned into quads.
Thanks.
But even when they are quads, I will still have many faces that make up the curved surface. Is there a way to unwrap many faces at once? That border only needs a solid color. The solid color must be on the same texture map withe wood and everything else for this model.
select all the front faces, go into front view then choose project from view. the sides may be trickier but it looks like they are all quads anyway so select the edge then simply unwrap and it should unwrap in a straight line of quads, near enough. do the same for the back face as you did for the front
Why? If it only needs to be one color, then just assign a material to them faces and set it to hue you’re after. If you need it textured, then you’ll need to clean it up and use seams and unwrap it that way or do it Small Troll’s way and use ‘Project from View.’
Thanks a lot! The project from view works very well…
Select all these white colored faces. (remember click one, cltr+click selects the shorter path)
Or simply select all other faces and cltr+I (invert selection) right?
U to unwrap, “reset” (the last one.
On the UV editor all these are selected now, right? S and 0 zero, to resize them as pixel. Place this pack of pixels anywhere on this wood texture. One color then. I hope this is what you are asking.
However, a better topology could help for further nice modeling.
IMO, the way you should go is.
Draw the outline of this model as you wish. F to have a huge N-gone. Inset for the border. Extrude as needed. Voilà,
You may separate the border, that could make your life easier. Bevels, color or texturing, subsurf etc etc .
Thanks for this (you were probably writing while I made my last post). I Actually modeled the sign in Sketchup. In Sketchup it was as clean as your example/suggestion. The mess is the price paid for exporting to Blender as Sketchup does not have proper UV tools. But I see what you’re saying if I modeled in Blender, thanks for the tip. I just left a small area with the off-white color and scaled the UVs into it after selecting in ortho mode and just deselecting the sign face and the back.

My guess was right then. I knew it was a SketchUp import.
So, I also used SUp on my post.
Try to export as DAE. Uncheck triangulation and export only selected.
Blender will import n-gons ! Great so far.
Pay attention though. N-gons in blender don’t support holes. A simple cut in SUp is the solution.
In our example, I modeled a simple n gon in SUp. The outline of this.
Imported in blender as a simple n-gon and simply used inset and extrudes for the border. Separated as two objects. Easier for adding/controlling subsurf and textures.
I will try the DAE method on my next exports. Thanks again.
