Fillets and object size

Hi Leonard, well actually your hardware is not too terribly ancient..

Did you actually run into problems with the higher density files, did things actually bog down and go too slowly to use?

I would think that you probably don't have to worry much about this unless you are getting into quite a bit larger in size than that. (EDIT: - yes if you were getting into the 100MB range then that would be good to optimize)

That's probably when you are producing polygon model output in Cinema4D - you can typically adjust the number of polygons that are used when generating polygon output.

In MoI things work quite a bit differently than that - when you create a fillet in MoI you are not building polygon output then, you are actually building a "perfect" circular fillet shape that is refined to be accurate to within 0.001 units tolerance.

That's one of the major differences between NURBS modeling and polygon modeling.

With NURBS modeling you are building something that is more exactly defined to be an accurate curved shape in its definition.

Polygons don't enter into it until later on when you save to OBJ format. (well, they also do enter into the viewport display but not the definition of your model data though)

At that time that polygons are generated, you will then have a similar chance to adjust the polygon density - you can use that slider to reduce the number of polygons that are generated and there is another setting on the full settings (push the little arrow in the lower left corner) called "Avoid smaller than" which can be useful for reducing polygon density in small details. You can enter a distance value there, and anything smaller than that distance in size will get a much rougher mesh angle applied to it so small details will get fewer polygons with that setting. So for example if you have fillets that are smaller than 0.5 units in size, you can enter 0.5 for that "Avoid smaller than" value and then those fillets will get a rougher meshing on them than the larger sized parts of your model.
