Alright I found a workaround for those of you outthere like me, who may or maybee didnt get the icons to work. It requires abit of editing in the layo_controlV3r3.hak . But its nothing to be afraid of.
First off, make a copy of your layo_controlV3r3.hak and rename your old one to something like layo_controlV3r3.bak. Its better to have a working copy lying around, if/when it goes wrong. Or you can simply download the working layo_controlV3r3.hak again here
Then you need to download the three icons that Gulnyr made, you can find those here
. You also need a hakpak editor. A very simple one can be found here
Alright now that you got all your basics you need to first open your layo_controlV3r3.hak in your editor. By scrolling down in the list you will come across 3 files called is_BracStorm.tga, is_CrackOrb.tga and is_Tempest.tga
Mark those three files and remove them, you right-click and press remove.
Then at the top there is a option to add files. Click it and select the files that Gulnyr made instead. Save your hakpak and fire nwn up, it should then work with these colored icons instead.
A reminder to people. You do this at your own risk, and if there is a possible update to Layonara where the layo_controlV3r3.hak is getting exchanged for a new one, you will most likely need to do it all over again.
I hope this have been helpfull. If you need a hand with it, send me a pm, or catch me on IRC.
Cheers and happy spellweaving.
