I tried the megamagnet-adaptation I found on this forum. But I've made my own version of the original magnet-tool that better suits my needs.
What does it do? Very simple:
-> just make named selections and than use the magnet tool on them. It is actually just locking your selections. You will not influence non-selected points. Yeah !
So basically you can now use the named selection sets drop-down of the magnet-tool.
I just modified the original file lm_magnet.lua.
I'm very sorry if someone has posted exactly the same modification already before, but I did not find it on the forum
I have no way to really upload it, but the source is right below
I hope I have not violated any rules by posting the source here or by modifying the original source file. I will definitely just stick with the new version anyway, so that's no prob for me
So, you know what to do now with the source? Copy just the source and paste it into a text file. After that you have to change to filename to lm_magnet.lua and replace (if you want) the original lm_magnet.lua.
Ofcourse you can make my modification into a separate new tool if you like/can. But honestly I see no reason why: if you want to "fake" the old magnet, just select all points first
