For those of you who don't know what C4Ds are, its the things that pop out at you, or go flying. Eg. My sig. The Blue ice/water kinda stuff
I've been trying to impliment C4d's into my sigs and I tell you I find it very difficult for placement and after downloading 100's which one do I use. One you have to change color sometimes, they work best as "dodge" "softlight" or "screen" in my program or if your brave and they are in the PNG. format then use them "normal". The difficulty part for me is what size to I make them?? In most of my sigs I make them small and "dodge" them for best affect. Just make a ton of sigs, request are the best practice, with C4D's till you get it down. When you use a C4D you will know if it needs to be in your sig because it will either look realy nice or like incredibly bad. Here are a few of my favorites: Note, you do not have to use the whole C4D just parts & reduce size.
Yeah I Made One Sig With A C4D I Found. Its In My Showcase(The one with the DAH Alien in it)
