Hi!
Is there a limit for the size of a texture atlas? 4096px?
To be honest I’m new to texture atlases and trying to figure out how to best use them with Unity.

Depends on the hardware. Earlier iPhone/iPod touch models = 1024. Older cards, most Intel chips = 2048. Newer cards = 4096. Recent cards = 8192, though I don’t think Unity can actually use that.

Thanks for the reply,
Let me give a proper example: Say you have a bunch of props, like 50, reasonably pixel-hungry things like walls etc., each wanting 1024 squares. What is the best way to get most of those textures without killing performance and how much can be combined?
Afaik, Unity’s limit for a single texture is 4096px, but does it apply to atlases as well?
In other words, if I have a 1024 texture for each prop, does it mean that I can cram maximum of 16 sheets in one atlas?
Thus, for texturing 50 props, I’d need 3 full atlases and some more smaller sheets? Or am I totally getting this wrong?
An atlas is a single texture. You take existing textures and make a new texture out of them. Again, it depends on the hardware. If you’re targeting mostly casual systems that don’t go past 2048, then you can only do 2048.

Ok, thanks for the clarification!
