I try to compile my new UI.map with Tool, and it says it's too big 7.75M or something. Is there a way to "bypass" it so it doesn't check for size?

not that i know of and tool should let you go 7.77 mb in size coz it lets me go up to 25 mb in size....dont try ai they take to much size and pass the limit in the ui so u can only have approx 6 different ai which sucks unless the ui is in a small map like engine room on d40

for adding ai, just remove their hud and dialog references from the biped tag. that will take all of the file eating tags out. ai sounds are what seem to take up the most space when adding ai
