Help needed. I am using Blender 2.79 - I have a dress that I modeled and then unwrapped in UV layout. The problem is that I never added any material zones. What I would like to do now is add materials by UV island without having to try to select all those proper polys in 3d menu. Is there a way to add material zones by uv? Any help is appreciated!

If you are in your UV Editor, you could select a Polygon Face of any island and then hit L on your keyboard to select the island , after that you could assing a material.
Hope that helps.
Good Luck
One way is to use Select Linked command in the viewport and constrain it by seams.
If there aren't seams already on the mesh choose UV > Seams From Islands in UV editor (when UV map is visible).
With seams available select a face of the mesh and press Ctrl+L (or L if mouse cursor is over the mesh) while in 3D viewport. In operator options (F6) choose Seams.
Now there will be selected only that part of mesh geometry corresponding to one of the islands.

$\begingroup$ Thanks. I tried that and it works to select the islands. But then when I try to assign the materials, they still all just assign to the entire mesh. $\endgroup$ Jan 15, 2019 at 0:51

1$\begingroup$ @VictorCsakany it seems that you selected islands in the UV editor. What this answer assumes is selecting geometry in the viewport, then if there are more than 1 material faces will be assigned to chosen one. $\endgroup$ Jan 15, 2019 at 10:46
