Hi all,
That's great to see you going this height in the resolution (me I can't go up to 180). Your creations have more and more complicated shapes and you're approching the maximum limit of Polygons and vertices at height speed . For your informations, I'm trying to make the maximum number of polygons and vertices configurable (like the grid resolution). If things are ok, you will be able to go up to 10Millions polygones/vertices , which is enormous but at least it should be possible...if you have enought memory. _________________ Cheers,

hi torolf
Thanx for those nice examples.
With Cult3d plugin it's really great to turn around your buildings.
I have a question to your "stone cube" example.
Seems to be a raytracing picture...
Which raytracer to you use and can you publish the scenery source
(I want to use it for other formulas too) or is it a secret?

Polys: 1.800,000 Mio

Hi all,
That's pretty big number of poly for a day by day use .
Two questions torolf :
1) Are you really going to use objects with more than 2 Millions polys?
2) What's the perfect number of polygones number limit for you? _________________ Cheers,

This balls are really impressive!
I think I can imagine how do create the ball with 2 colors.
But I have no idea how to colorize that ball with 3 colors.
What's the trick behind it?
