Interesting stuff indeed,

I have noticed that alot of texures for products here and at other places, have textures that are 3000x3000, does that mean that Poser 7 or Carrara(as I use this also), is having to allocate memory to this texture as if it was actually 4096x4096.

The reason I ask is that I regularly reduce my texures by half to get better memory usage so (3000x300 would become 1500x1500. But is the reality that the software or my system, will actually 'optomise' this texture size to 2048x2048, which would mean I am not getting the memory saving's that I expected.

Or am I just way off  base.???
