I have the model of house with seams on it. model with seams marked
When I'm trying to unwrap it (U > unwrap) It unwraps wrong. messed up UVs Some polygons are bigger then others, and I don't know what to do. How do I unwrap it proportional?

    $\begingroup$ the easy way (but with less control) is to use some automatic unwrap method (cube projection, smart unwrap or lightmap) in the U menu. Learning more about UV mapping could help you in the future : cgcookie.com/blender/2011/01/21/intro_uvmapping $\endgroup$

this happens because either :

  • have edited the mash after unwrapping

  • have scaled the object after unwrapping

to resolve this :

  • apply scale : Ctrl+A and select scale
  • unwrap the mesh again

    $\begingroup$ notice that he has a seam on every edge? if he was to doo smart UV project, he'd get proportional, but it would be a mess. My guess is the thought process went like this. "Hmmm... unwrap it like a teddy bear... (that's how I learned.) Well, this doesn't even look like a teddy bear. so I guess I can [A] > [Ctrl]+[E] > mark seam. hey! there we go! $\endgroup$
