A quick question about texture precision.
Is there a limit to how precise the u,v coordinates into a texture can be ?
I have 1 big (2048 x 2048) texture where every object maps into 4x4 pixels to get their current color (don't know if this the best way of doing it, but right now it kinda works) and if an object has to change size I dynamically change the texture and reupload it.
So far so good, but sometimes the object have some color from another object on the edges, so i was wondering if there is a limit to how precise the indexes can be ?
