    Hey there,

    Im trying to set up a texture that selects from 2 images when spawning particles. I dont want the images to animate. I simply want to emit 2 different textures from one texture sheet on particle spawn.

    Heres the texture


    Any help would be greatly appreciated!

    I don't think that is possible at the moment, I wanted the same a while back and ended up duplicating the particle system and changing the material and then choosing one or other of the particle system to emit from at random.

    Yesh, that's pretty rough. Going to end up with a looooot of emitters.

    Cheers for the reply.

    There's two ways to do it. One is to have the texture be tiled vertically and use "Animation" > "Single Row" instead of "Whole Sheet". The second way is to set "Frame Over Time" to a range between to constants instead of a curve. The single row feature is nice because it allows you to have a random image per particle that also animates.
