I am trying to use mental ray displacements here and can’t seem to figure out what the disp approx modifier is for exactly. It seems to be having no effect in mental ray at all. Is the displace approx modifier intended only for 3ds scanline renderer? or am I missing a checkbox somewhere?
And if the displace approx editor is only for scanline, then where are the more complex mental ray displacement controls?
As far as I know disp approx is only for the scanline.
There are several ways of using displacement in mentalray, just one of the ways is to create an Arch & Design material and place your disp map in the displacement slot. Disp settings can be found in the render dialog box.
The mental ray displacement settings in the render dialog box are missing alot of options. Mental ray has a pretty comprehensive list of displacement settings. Is there anyway to uncover these options in the UI?
