Nurbs rendering ? Or polygon ?

Would converting the nurbs into polygon in advance aid the rendering speed ? As I think gaining more control on the detail of the polygon would be a better trick to shorten the time consumed.

Maxwell will always use your render meshes for rendering (it does not use NURBS directly).
The main thing that will speed your renderings is to keep your emitters extremely simple; just a planar surface ... one polygon (the normal of the surface will determine the direction of light).

I know that MW do convert the NURBS into polys b4 the rendering (sth called tesselation ? ), but I wanna have more control on how fine they convert.

This is converted by Rhino, so you need to refine your mesh settings (document properties)

um..it seems that the only way to be sure is to convert the model to polys in advance.

I think I can try to convert the model to meshes manually, but of course, duplicate and hide the original model.

There are some suggestion in the "Advance Studio Quaility CD" of Flamingo.

how do you have resolve the problem?
my simple first try with new beta... is faster than old alfa ..only 30 minutes
what's your model units? try to set it to meters (and allow scale model), set Mesh quality to Jagged&Smooth...

now i try as suggestion to set meter and scale
tks
as I saw, Maxwell has a little problem with very small objects - so it should be some curved surfaces etc.. and native unit inside Maxwell is 1 meter, so there should be problem. Try it.

No you don't need to create mesh object... I have never had a problem with this.
If you play with the custom render mesh parameters you shouldn't need anything else.
If you
have to mesh an object individually, then just use the "MeshingManager" dialoge.
