    New to VFX graph, but loving it so far.

    I'd like a way to generate particles that use a random texture from a predefined group. Is that possible?

    I've tried looking at the Texture2DArray node, but it doesn't seem possible to select a random texture.

    Has anyone done anything similar?

    Hey. At the moment, you need to pack your textures in a single texture sheet and use flipbook mode on the output to select the texture you want. Frame selection is done using texIndex attribute that you can randomize per particle.

    Ah ok, thanks.

    I'm already using texture sheets, so perhaps I'll just pack a bunch of them into one.

    Thanks for your help
