DrawCall Texture Atlas optimization

Recommended Posts

Hello, when I make 3D models I usually make a texture atlas to reduce number of DrawCalls. Is that the case for PIXI?

Do we need to make an atlas for PIXI or maybe PIXI renderer handles multiple graphics efficiently?

If not is there a good tutorial out there?

Yeah, use TexturePacker (paid) or Shoebox (free) or spritesheet.js (free) to make a texture atlas. Better with padding. PIXI batches all sprites automagically, and uses a number of texture locations at the same time, so if your entire stage has up to 16 atlases, it'll be rendered in one drawcall.
