ok i get this error when i export a sprite bitmap:


D:\Games\halo ce>tool bitmaps effects\particles\solid\bitmaps
Couldn't read map file './toolbeta.map'
### snow burst.tif
### ERROR can't extract sprites without a valid plate

what is that a valid plate???

a valid plate is a 4pixel blue boarder around the image, just make a new image, 4x4 pixels bigger than ur current, then put ur bitmap in the middle of it, flatten it, then expory & compile
