i'm having a problem with sampling on textures with fine detail in
mental ray.
basically i have a concrete texture with lots of detail that renders too
blurry, the same shot renders nice and sharp with a maya software
render. setting MR globals filter height/width to 1 gives a pretty good
result for the concrete in MR, but then the anti-aliasing on other
objects in the scene is really bad. setting filter height/width to 2
fixes the aliasing but blurs the concrete texture too much. :(
the shader itself is just a standard blinn with file texture mapped to
color, mipmap filtering on 1 (having tried dropping this value but
doesn't seem to effect MR). i liked the ability to have more independant
control with aliasing and sampling with the maya software render... is
there a way to get a sharper concrete render while keeping the good
anti-alising in the rest of the scene...?
any tips greatly appreciated.
