Hi mdesign, can you please post your original .obj file too?

> Is there some way to convert it with some less resolution? With lower subd level to have less points?

You need to create a lower resolution control age to get a lower density conversion. There isn't any way built into the converter to reduce control cage complexity, it's assumed that you will have already done that in your poly modeling program.

Maybe you have an very very different definition of "low poly" than I do? If you have like a hundred polygons across your object that is not what I'd call low poly at all.

For filleting you would need to avoid these kinds of very tight bends in your object:



There isn't any way that a fillet is going to be able to cross over that tight of a bend without the fillet getting all bunched up on itself.
