I’ve never had a problem with this system for small sokoban or puzzle games or just simple roguelikes without any major ai or mechanics. I’m trying to test the performance of sprites vs quads, however, for some reason the sprites are properly using the same VBO while the quads not… it doesn’t matter if they are static or even an external mesh, Unity never reuses the same VBO resulting obviously in worse performance than sprites which share the same VBO. However, we noticed this caused problems with the existing dynamic batching. Tight: Choose this value to generate a Mesh based on pixel alpha value. You can turn off Shadow cast for one. I’m making a game using sprites and a perspective camera for a ‘free’ parallax, however, sometimes I change my texture atlas to increase the resolution of some sprites in order to have roughly the same 'virtual’ppi on screen… however, it’s a real nightmare changing the sprites as the actual object will change also because the size of the objects are calculated You should use a quad with Standard Shader in Cutout and a duplicated and flipped quad for opposite side. To render objects efficiently and reduce overdraw, I decided to convert 2D rectangular sprites (with default sprite transparent shader) to 3D quads (with opaque shader). The quad is however a mesh, which doesn’t favor sorting between 2d layers. It cuts them up into separate sprites, so for one sprite sheet you would have 3x4 = 12 sprites. Free asset used in this video from Dec 3, 2022 · I want to apply sprites onto quads and I learnt that you have to convert them to materials first before applying them to quads.

As far as sorting is concerned, using Unity sprites with the Sprite Renderer component allows you to assign sorting layers so you can control the rendering order without messing with the z position. Our game try to be really cheap in terms of cpu/gpu.
