Every time I “unwrap” the UV map is all over the place, even off the board. Is there a way to fix this because its rather annoying, So far the only “fix” I’ve seen is using a planar UV map but that doesn’t work for something like say, a helmet.

UV mapping is a whole art form in its own right.  There are basically two methods - projection and unwrapping.  Projection is a quick method which only gives good results on simple geometric shapes which resemble the 3 types - cube, cylinder and sphere.  Anything organic needs to be unwrapped using seams and pins.  Unless you assign temporary shading domains to each flat part of the mesh and do a planar map for each.

Basically, to unwrap, you look at the mesh and decide how you would cut it up if you were making a paper pattern to lay out flat.  Then you make seams along the edge loops which represent how you would cut it up, add pins in appropriate places which serve as a fixed point around which the UV map flattens out symmetrically.

If you would like to post the mesh on a file sharing site and PM me the link, I’ll try to show you a step-by-step:)

I’m math dyslexic.  When the Unfold tool turns things upside down and inside out I want to cry.  But using seams keeps the tears down to a minimum.  smile
