I have made some MR shaders originally for Maya,
but since MR shader work across different packages I made 3dsmax gui declarations so they also can be used in Max.
A fisheye lens shader with extra parameters to get some funky stuff.
A panoramic shader with a field_of_view parameter to make it work from 0 to 360 degrees.
I have also added a automatic adjustment of the camera angle when field of view < 360.
A simple wood shader.
A phong wraplight material shader for MentalRay for Maya.
Made with help of: http://www.nanomation.co.uk
In the example image you can see the top sphere with an ordinary phong shader lit from the sides.
Notice the dark shaded band around the center.
On the lower sphere the JS_wrapmaterial simulates the real world scattering of light that makes the lighting seem to “wrap” around the sphere and eliminate the dark band.
Adjust the wrap_factor for the wrap effect.
