    I have serious multi textures problems.

    I have a relatively sophisticated landscape. I want a mixture of grass and stone. I can’t get the textures correct.

    I’ve tried two things… neither of which made me happy.

    First, a layered textured with a simple noise layer map. Nope. Then, I tried multiple textures. It only renders one… the one I have selected. It doesn’t seem to matter which one has “Mix Textures” on or off… I’ve tried every combnation. If I select the grass, I get grass. If I select stone, I get stone. If I mix only one, I get a horribly washed out mess.

    I even tried a “noisy” alpha map (same map, but inverted on one) to try and show one through the other, but it made the whole landscape wierd ( which I may can use later :-} ), but not what I want.

    I want grass and stone … with appropriate bump.

    Also… in playing with all of this… my bump no longer works at all…..

    I’m lost.. .It’s late… I need help.

    Is there a good tutorial on working with textures, shaders, etc? I can never get them the way I really want them.

    So here’s the thing… to simpify… what if I want a vase with a painted center. I’ve got materal 1, the green marblish finish. The 2nd materia is the band of paint. Here’s what I’ve done:

    How do I get the band to not be partially transparent? I’ve tried several mix modes… nothing seems to work to make the band solid.

    Never mind… I figured it out… I’m trying way too hard to make it hard…

    I just needed a 2nd texture, no mixing, and an alpha…

    Sorry to bother you.

    can you post the scene and textures? There’s more than one way to do this and you don’t necessarily need to mix textures

    It’s a rocky surface with grass mixed in… I clearly need to learn how to make grass with the fur module. But here’s what I have…

    The stone and grass are both from a photo. UVW mapping tiled 20 and 15 times respectively.

    The grass uses an alpha map.

    Any siggestions are welcome… meanwhile, I’m in search of a “fur” tutorial … hopefully how to make grass. The main question then will be… can I make grass with the alpha so I have areas of grass, rather than a fuzzy surface.

    [Joseph M. Morgan] “The main question then will be… can I make grass with the alpha so I have areas of grass, rather than a fuzzy surface. “

    absolutely, put your alpha map in the Length channel of the hair material.

    To make grass …well, what kind of grass… for quickie lawnish grass (and a place to start) drop in a plane Add Hair – make it green and green with green/green-blue Specular, in the Length channel add your alpha, make the Thickness be 5 bottom, 5 top and Variation of 2, add Bend and/or Curl play with the values. From there there are many possibilities it just depends on the look you want.

    I had already taken a guess and put the alpha on the density channel and it worked as I expected. That is, grass where white is, no grass where black is.

    I’ve managed to increase my render time exponentially… definitely must look into building a new machine for this 🙂

    What would be the difference if I put the alpha map on length?

    And… it is working really well… I’ll post a pic later, but any ideas on making weeds?

    Before with a texture map:

    And here it is with grass ( 10 minute render for a single frame )…

    weeds – thicker maybe, taller, but with a large random height I would think. Maybe the Feather Object could do a good weed. And maybe more than one set of hair for maximum difference. Something like Nature Spirit or XFrog would work (not free though)
