Aprilgem: Thanks for the video link.

Electroglyph:  Thanks for the great explenation, the Charles Schultz method does make sense.

I want to do some mixed 2D / 3D work and I think I will start working with Higher resolutions.

Anyone here use a rule of thumb for selecting High Resolutions to work with? Like 5000x5000 or 10,000 x 10,000??

Come to think of it, I will probably need a new computer with lots of RAM to push all these pixels around.
