Blender 2.5 uv island scaling

FreshDumbledore

Is there a function for shrinking and fatten uv islands in Blender 2.5?

in editmode you can scale along the normals with alt+s. I want this for uvs where every island is scaled along its center.

At the moment I have to scale the hole uv set down and reposition every island by hand. It's ok for small textures but for bigger lightmaps it's horrible

have you tried UVs->pack islands ?

there's also the average island scale in there which is pretty useful.

FreshDumbledore

yes I know those functions, but I need space between the islands. so pack islands and average scale won't work for me.

but thanks anyway

Here's a dirty trick then, that might work:

average the island size, then pack them, then scale one of the islands down, average size again.

haha a real dirty trick !! with some manual twicking it's a solid workaround


When you use smart project there is an option names "island margin" which would be perfect with normal unwrap... but it doesn't show up.
is there a script anywhere?

but I use this trick until there is a proper solution. Thanks

Since most things should be in python in 2.5, it should be accessible somewhere to be attached to the other script, but more than that I do not know, I agree it's needed though
