Hi! Can’t find a way.
I have spritesheet of several feathers that i want to act as particles.
I set particle system - then assign material which is a spritesheet already sliced in unity and set render - with alpha transparent. The thing is that the whole spritesheet is generated as particle but i want each particle to be randomly taken from the spritesheet so the feathers will be different(i have about 8 variants).
Please help.
It is possible, and I use the technique extensively… Not only to produce variation but also to allow all particle emitters in my game to share a single material.
In the emitter’s “Texture Sheet Animation” settings, assuming you have a sheet of 16 different feathers in a 4x4 grid, set things up this way:
Tiles X:4 Y:4
Animation: Whole Sheet
Frame over time: (select “random between two constants”) 0 to 15
Cycles: 1
Play around with these settings to see how you can use them to incorporate multiple particles onto one sheet. For animations or randomization as you’re doing, I usually put all the frames on one row and set the Animation setting to Single Row instead of Whole Sheet. Anyway, experiment with that.
I’d split then up, create an array of a variable for the materials, and select a random array element to assign personally.this allow you to add, change pieces of art without re doing the sprite sheet. Otherwise there is a YouTube bid called like, unity advocate texture, that links to a script that can handle that via it’s index variable. Being on phone i can’t get to it though.
