So what sizes are of interest. I've been using 2 meter sheets for testing against big props and that seems to work pretty nicely.

For the grid unit, I was thinking to make 5mm, 10mm, 20mm, and 40mm.

On a 2 meter sheet, quads produce:

5mm = 400 by 400 = 160,000 polygons (ouch)

10mm = 200 by 200 = 40,000 polygons

20mm = 100 by 100 = 10,000 polygons

40mm = 50 by 50 = 2,500 polygons

For the bisected quads (three flavors) you double the polygons.

For the hex tesselation, the number of polygons increases by about 15.5%. So the 20mm version is about 11,500 triangles. Considering that it is far superior, that's a pretty good benefit for just a 15% increase. However - I suppose no common modeling tools will let you make those!

That's four sizes times 5 tesselations, so 20 props. Sound reasonable?
