Ryder Spearmann has been doing some sculpture work with the my SL Testbed for making sculpies in modo. After some investigation he found that the gradients I created are “eased” (which is the automatic form of a gradient in Modo). This causes distortion at the outer edges of the sculpie, so I’m pleased to present the improved testbed. It can be downloaded from:

Here’s what the gradients used to look like–note the curves:
Here’s what the new, straight line graident:
Great of you to blog this so fast… I knew something was up when I bakes a spehere map… but it was a rounded cube when placed on the sculptie.
The other thing I am doing, is to start with a sphere that is made of 32 segments and 32 sides. This provides a vertice for every point that will be made in the final high rez sculptie. This way, I can be rather assured that I can map individual points with precision. I also make the sphere 256 mm cubed… and size the texture locators to it, which means that at every 1mm spacing, you can assure a distinct color change in the map (the finest color/position resolution one can have).
I have not yet tested to see if this approach indeed does provide absolute control of each point… but from appearances… it seems to at least be rather close!
All the best…
