Using one atlas for static and changing character textures

Archived Forums Questions & Answers

Hi,
I am working on a mobile game and need to keep drawcalls at an absolute minimum.

I want to have 2D-animated facial textures on the characters. The different facial expressions will all be in the same atlas, but can the non-animated parts for the rest of the skin and clothing be in this atlas? Only the UV for the face will be the part that change states.

This way I can save on drawcalls and since this is a big project it is easier to maintain one atlas instead of several.

Thank you all very much in advance for helping me out.

I’m not sure where the question is in here. Yes you can have all your animated and non-animated in a single atlas. The trick will be setting up the uv coordinates to make it happen. Note this only buys you reduced draw calls if materials are shared. If you are using a bunch of different materials for your non-animated parts, then you will get a draw call for each material.

Yes, the material will be shared. Thank you for your answer, that is all I needed to know. :3
