Ahh yes, it lacks scale. I've had to do separate objects at different scales. Also if you used uniform scale on the "object" you needed to reset transforms before AdvPainter would notice the scale change. Very annoying. Weird, that was the script I was looking at, but it came from another place. I tried out the wire bundle…
I haven't tried out Neil's yet. Does it come with spline painting? I think someone else made a separate script that paints splines, but I only ran across it, shouldn't be too hard to find again but I lost track of it as I never tried it out. AdvPainter works well for what I need it to. Spline painting comes in really handy…
It's missing something I needed, maybe it was random scale? Neil has a splinePainter, might be the one you're thinking of. He also has that wireBundler script.
The only bummer with Advanced Painter is it won't randomize the rotation IIRC, have to run another script afterwards. Neil Blevins' objectPainter might be better, haven't tried it yet. http://www.neilblevins.com/soulburnscripts/soulburnscripts.htm
