Im afraid the visibity of the paintballs is somthing that requires rescripting the balls, which is quite a long part of the programming, atm you can see the balls but its pretty damn hard, and bloom effects dont help.
my point is that although they have the source engine doesnt make it a matter of skinning and mapping. They have completly re worked the "bullet" physics for a paintball, re modeled obsticals and worked on the guns. They need more help and this alpha version will hoepfully pull someone into helping.
I only know so much as ive been patently been watching and waiting for this kind of progress, and as for saying it will only take four months to make a mod, this is true, if you dont have a job, work and or school too. These guys are doing this as a hobby, not a job. So progress wont be fast without the interest.
