The results will vary depending on rendering settings Object
Accuracy. If that is set to .5 pixel then your texture resolution
can be 4 times larger (2 times larger in width and height of the
texture.) and the fidelity of the texture will still shine through.
This will benefit when you have a texture that contains very fine
lines. Going larger than this an Carrara may break up these fine
lines (E.G.: a simple texture, white with single pixel line(s).)
But then I'm probably just adding to the confusion. I'll go away
now. :)
