Texel density question

dzibarik

So let's say I have established that 1 meter = 2048 pixels and after I have unwrapped my mesh I apply this texel density to each island. And I have this small mesh which is like 10 centimeters in diameter. Does it mean that there will be a lot of wasted space in UVs for that mesh or does it mean that I just lower the resolution of the texture while still packing my UVs tight?

I just do it by guess-timation. I pack everything pretty evenly, so the texels are all the same size on the model, and use the most space. Then I try to pick a texture size which is the closest in resolution to my desired texture density. Just a visual test with a checker bitmap, are the pixels too blurry, too sharp? It's never perfect, since we're stuck with powers-of-two sizes, but it's usually close enough.
