Hi everyone! So should i have one big 4096x4096 or bigger texture for all the objects in my scene, or should i split it up into smaller textures.

thanks!

Depends on your needs. Usually there is no noticeable difference unless you come close to certain limits (e.g. GPU memory, loading time …).

Atlas textures speed up games, but this is do to static draw call batching, or geometry instancing, or material bucketing,

saving drawcalls by drawing all objects using 1 material, in 1 pass or more.

if you use the same maps over and over again you can get a very nice result with not a very big atlas*
