i have 2 questions i am hoping you all can help me on.

fist is about surface styles and there role in maxwell. do any of the values (diffuse, specular, etc.) affect the surfaces in maxwell? i realize the maps come through, but what about just the slider values?

my objects that are rounded are rendering facetted. how do you get objects to render smooth?

thanks.

Hi tperks,

fist is about surface styles and there role in maxwell. do any of the values (diffuse, specular, etc.) affect the surfaces in maxwell?

Maxwell just gets the rgb colors to apply a diffuse color to the maxwell materials (except for metals) and also maxwell gets some maps an the smoothness and amplitude values of the maps as is described in the manual. The most of the formZ surface styles parameters are not required to setup maxwelll materials.

my objects that are rounded are rendering facetted. how do you get objects to render smooth?

You need to increase the tessellation or the smoothness attribute in formZ (check the formX manual, there are different ways to handle with it). Maxwell can get facetted objects and smoothed objects from formZ. In the other side, if you increment too much the smoothness you could get undesired results, I suggest you to limit the smooth angle. It happens because the smoothness is a trick, a normal vector that is not perpendicular to the surface in the point is not a normal vector indeed, it does not happen in the true life. So the light behaviour could be weird if the smooth angle is too antinatural. It If It is specially important for dielectrics.

Best regards,

Juan

Juan, have you seen this post?

Juan

so to get an object to render smooth or rounded looking, i have to increase the facets? i form z i usually just have it render any faces that meet at an angle greater than 140 degrees as smooth. these attributes don't come through to maxwell. am i correct?

The playing around I have done with some round smooth objects is to crank up the display resolution to the highest. It seemed to have done the trick for me.
