    Default In the midnight hour, he cried moire, moire, moire!

    Anyone have any knowledge on how to reduce moire patterns in asset models? I've got a set of three brick houses and the bricks (9"x4"x4") with the mortar in between are driving me nuts! The only way i've found to deal with it so far is to stretch the texture mapping a bit, but then the bricks don't look right.

    Suggestions?

    Set the object's mip LOD bias to -1 in 3DCanvas. I think a plug-in is required. I don't know which one.

    Forget -1, try -3 or -4.

    Do you know where a plug in for mip bias is for 3DCanvas 7 & 8 is?

    Nope, I don't use 3DCanvas.

    However, if you can export it to a .s file, you could edit the MIP bias in it to see if it makes a difference.

    Well you can export in 3DCanvas to .s but RS/RW takes .igs. So I don't know how that would work.

    Sorry, I forgot which forum I'm in. Brain was in MSTS mode...

    Default -1 works just fine...

    That will remove mipmapping, but does nothing to address the Moire issue. It also creates a shimmering effect during screen redraw, and IMHO, is just as annoying as Moire patterns. Except for glass and a few other alpha parts (0 or +1), -1 is all I use on all other objects (MSTS and RW), and I cannot think of any reason for lowering this value.

    FWIW, reducing Moire is handled through video card settings.

    Jerry,

    Not an official correction… but I’ve noticed, that if you reduce the visual impact of your texture, the moiré effect seems to reduce proportionately.

    In other words minimize the sharp lines and contrast. Maybe go as far as putting a slight ‘blur’ on your texture. It’s worked for me.

    Have a sparkling day,
    Bob
