    What happened to Mental Mill?

    I've just seen this page:
    http://www.mentalimages.com/products/mental-mill.html



    What does that mean for us, users?
  2. Filtered texture sampler used as displacement (3ds Max 2012)

    A filtered texture sample (texture_lookup_filtered.msl) doesn't work well as
    render-time displacement: the entire surface gets a constant value, which
    seems to be the sample from the dead center of...

    Can not render MSL node tree twice

    I have a shading tree made up of MetaSL nodes. Nothing fancy just texture
    samplers, multiply, lerp and a few other basic operations.

    Trouble is that Mental Ray can only render it once: any...

    A frac(tex_coords) fixes it but it's not very elegant.
  5. Filtered texture sampler doesn't do tiling (3ds Max 2012)

    I'm using filtered texture sampling (as seen in texture_lookup_filtered.msl)
    with MentalRay in Max 2012 (SP1). Beyond the border of the 0..1 UV space I
    get black instead of a repeating texture....

    Yeah I copied them from there. I'm just not sure if I grouped
    them properly because I don't know what many of them do.
    "Virtual" and "void" should be in one color group? Stuff like that.

    What editor to use for writing MetaSL shaders?

    So far I was using Notepad++ but it's lack of proper support for the
    MetaSL language is a letdown. Handling several shaders in a single
    file is a pain in the ass as the fold/unfold functionality...

    I've just realized what produces the blurry areas: MIP mapping.
    The affected polygons are at a high angle of incidence relative

    Thanks steve. I don't work with Maya any longer but I hope
    someone will continue experimenting with this and eventually
    get baking to work with MetaSL shaders.

    Edge detector shader?

    I'm looking for a shader which can detect sudden changes in topology: edges and corners.
    I found one such shader but it's kinda old and doesn't work with Max 2011, so I thought I ask
    around here.
