Atlassing the Baked Reflection Atlases

[KappaKawai]

Hi, is it possible to gather up all the baked reflection 2d texture atlasses of each objects into one big atlas and make it work for all objects?

For example, There are 3 lakes in my game, All 3 game objects share the same water shader material but if I bake that hemispherical reflection on each of them they will require theit own local reflection atlases. But if we somehow can fuse those 3 reflection atlases of each lakes into one big atlas and put on the shared material of 3 lakes, They wont need seperate materials or textures saving draw call and maybe a bit of memory. guess there are 12-20 ponds or lake in a big openworld game 😅

is it doable?
