Well my Problem is, that somehow Maya works too inaccurate for my taste. I dont know if the operations in Maya can be made even more precise by changing some options, but all my “tolerance” sliders are at 0.0000 already.
Look at this one:
Plz go to http://de.geocities.com/cshapeshifter/ and then click on hole.jpg
Everything is done in NURBS, a sphere (1) intersects with somekind of cylinder (2), then with another stretched sphere (3) and last with a long plane (4). I’ve done this, so that the sphere is visible all the way through the 3 other surfaces. I made these intersections and then trimmed the useless things away. Everything seemed ok.
But you see in the render two thin gaps on the sphere, one caused by unaccuracy on the intersection with the sphere (3), and the other, shorter one by the unaccuracy on the instersection with the Plane (4).
I looked very close at the sphere (1) and these gaps seem to be caused by the other surfaces coming to mach in the sphere.
This is really really annoying, because I want to make perfect NURBS-Objects, and like I said, all the tolerances are at total 0. But it seems that maya cant calculate these operations accurate enough.
I hope, that these gaps are caused by me, and not by this expensive piece of software. I really hope that I just have to turn some options higher somewhere, and that you can help me.
Thanks in advantage,
*edit: and oh, i forgot, I use extremly high tesselations on these renders.
