Anyway to modify explosion VISUAL's and VISUAL RADIUS?

XD completely pointless but i feel like personalifying my nade explosions eg.smoke on my screen is a big @ss purple blast?

and I know this may sound weird but we can't modify the visual time it stays there for can we?,Also can we modify the ground marks left?

AND the files i would need to extract/edit would be nice as i have no clue what i am looking for .

Thanks in advance,

Admanms.

Uhh, Isn't there a thread that says what each file is for.... Anyway, I guess you could change the colour of it to transparent, so it's like it's not there aat all... I dunno where though, sorry.
