Invisible colour

[Klomster]

Greetings.

I am making a small mod that features adeptus mechanicus from warhammer 40'000.
Perhaps not fitting, but i don't care.

Here are the problems i have run into, and with a bit of help from you, wan't to fix.

What colour should i use too create invisibility?

I've tried white, black, i've used no background in photoshop, nothing works.
Is it a specific rgb colour i need to use?


And i am also troubled with the fact that one of my weapons doesn't work.
Namely the earthshaker artillery cannon (i know, overkill on the poor fantasy guys but i wanted to do this mod)

Code: #newweapon 603#name "Earthshaker"#rcost 50#dmg 200#att 4#len 5#nratt -3#sound 18#armorpiercing#twohanded#range 150#ammo 12#aoe 50#nostr#secondaryeffect 171#explspr 10113#flyspr 100 1


It doesn't show the explosion effect i told it too have and it isn't aoe as i also told it too be.

Theese are the main problems, hope i get answers.

Basilisk mod stats.

Theese are the artillery unit codes, weapon and unit. Some things are unbalanced but that is a later issue.

Like (for some reason, the mod file is correct) skitarii troops (infantry) have 1000 castle defense each instead of 2. I'm working on fixing that.
