omg thread just got gayer!!ohhh i get it, you want leaves and butterflies flying around the map <3

but i think its an important difference if you want animals running around the map or if you want stuff like snow or rain.
"floating bitmaps" can mean a lot of things: float around the screen the way a mouse pointer does it, floating around on the terrain (like ground scars or ally cursor widget) or floating around full 3D like planes or snow flakes.
for the animals its important that they are always updated while snow other weather effects only need to "happen in front of the players camera." At least thats how most games do it i think. It makes a different how someone would implent that i guess.
some maps already have rain and snow...dont know how that works though. i think some were done by smoth and argh?
and for animals maybe annoy the ca team until they change the chicken ai to include butterflys instead of monsters?
