How sprays work?

Barbon

everytime I seem to do one I do it with different formats like jpeg etc and they don't seem to work. What is the best way to do a spray pls so it works?

I change it to 24 bit bmp or png and crop it if needed on mspaint

Hei

if it's a jpeg resize it to 256x256

Your dimensions should be multiples of 16 (i.e. 128, 256, 512 etc) 512 probably being the upper limit. and I usually save my sprays as .TGA files. You can add transparency via the Alpha levels in a program such as Photoshop. If you want to make an animated spray look into a program called Sprayr. There are roughly infinity resources on the Internet about making sprays. Good hunting my friend.
