Island margin for Smart UV unwrap and pack islands gives different results for same island margin value
If this is not a bug then i would like to know the relation between the two values as im using them both in a script and would to get similar results in both cases


Smart UV unwrap with 0.02 margin


Pack islands with 0.02 margin

I can reproduce in 2.90 and 2.83.X, but this was "fixed" in 2.91 by rB850234c1b10a: UV: port smart project from Python to C

So please try a fresh 2.91 build from https://builder.blender.org/download/

Will close as resolved (but feel free to comment again if issues persist)
