Packing particles textures into one map
I have in my game several types of smoke textures that I use heavily in form of particles. Most of those textures are size of 256x256. I was wondering if packing them up into one bigger texture (1024x1024), rather than storing them all separately, will increase the performance of the rendering process? What's your opinion? Or does Unity do it somehow automatically under the hood?
If you have 10 different textures, that means you are using 10 different materials? In that case you have 10 draw calls for those 10 mats. Could be a good idea to pack them all into a 1024x1024 in order to use just one material. However it depends, if you don't really need to get those calls down you maybe don't even have to bother =)
Hope it helps
