MAKING BAMS, problems about making original BAMS and green bottom visible IG Options

[Rigel]

Hello i'm working on a MOD for BGT-BG2 called "GOODS of FAERUN". It's a MOD who add some merchants, few little quests and a lot of new items. I will make a merchant who sell armors and helmets of diferent colours but with no special caracteristics, it's just a black helm, or a dark red plate for fun, just to be fashion; however...

I will also create new ITEMS, and in that purpose, i need to create new bams; i will recolorize existing bams with news colours schemes.
I make 2 bmp files with a selected bam and after i work on them under GIMP 2. Next i use ITEM GRAPHIC CONVERTER to get a "quite" new original bam.

It's quite easy to do but i've got a big problem: i see the green bottom of the bams IN GAME; i've made some ressearches and i think it's a ALPHA CANAL (who set transparency) problem. It's like some graphical zones were losing their transparency during the change betweeen bam file becoming 2 bmp files.

So if someone know something about that graphical problem, i would be so glad if you can help me, and explain me how it works exactly, and how dissmiss that green bottom, if you can indicate me a tutorial it would be nice too. I'm not afraid of complicated explanations: i want to know all about that subject, cause i need to be a pro item creator.

Hello just wanted to announce that i finished traduce this tutorial for re-colorize bams finally (it toke me more time that i was thinking it should ) and that it is now available here : Bams re-colorization tutorial in BWL's Graphics-related tutorials section.

Thanks Tervadh for your advice, yeah i think i downloaded bam Batcher but didn't installed it yet, cause was not sure you can set transparency problems with it, but i will look at it cause its looks better in your words than in its "official" presentation.

Here some new original bams i created (maybe i will do another Tutorial for create original bams later) :

Nice work. Though it looks like the pommel of the second sword is cut off on the left a bit. You may need to expand the frame on the left by a pixel so it is a bit more round like the first sword's pommel.
