Lets suppose i have a big atlas (meaning 4096 x 4096)
and have a home with tables, flowers, chairs, clocks, door, beds, etc.
Every object’s uv is poiting to that big atlas (overlapping uv).
What i´m looking for is to créate many materials pointing to an unique big atlas texture. In my game there is not so much objects of course.
What happens if I créate many materials (diffuse, diffuse+normalmap, diffuse+spec, etc…) pointing to that big atlas… does the atlas Will be shared or multiplied by the number of requesting materials?
