beta release - fur material

The application of separate material to a fur material is not responding as anticipated. ie. texture maps do not appear on the fur strips only solid colour. I am assuming I would create the applied material to fit a surface 1x1 parametrically so it sits on each fur strand.

It seems to work fine in the material preview, but fail in a render...

  • Thanks, I'll have another look at my setups to check.
  • Hi Robert,

    If you look again at my example you will see that I used a JPEG and it did work as a stencil the same way it does in modo. I think the problem that you and other were seeing (glowing edges) happens when you try to use opacity map and not the layered method that I showed.

  • Sorry Jerry, I understand this, I just wanted to link to the other thread because it seemed they were talking about the same issue of mapping a material onto fur blades.

    Although you do mention the modo version...  looking at thier shader tree they seem to use a noisy jpeg for thier stencil. Are they modifying that stencil layer with some sort of histogram modifier to clean up the jpeg ie force black and white?

  • Hi Robert,

    Here's the deal modo 401 does not support RGB Alpha (501 will) so we automatically create a proper stencil ( not a noisy jpeg one). This being said you can still do precisely what you are asking for by using Alpha layer in the material editor. I used a JPEG for the alpha just to show this does work even with JPEG. In the Map Editor you see Leaf_Alpha this is a black and white image where what I want to see (the leaf) is white and the rest of the image is black ( think of this image as our stencil in modo land).

    As you can see I set the blend mode to Alpha for this layer and I create a layer for my leaf (Leaf_A.tif) I drag this layer below the Alpha layer and I am using no back ground ( that will render transparent). Now you can change the texture to whatever you like see example1 below where I used Wood Chesnut Crown (now I have wooden leaves).

  • Hi Jerry,

    Yes these are jpgs from the luxology asset site (I inverted the stencil/mask file), and I can see that combining them in photoshop to create a TIFF with alpha or transparency works. However if we are using the Luxology Engine and picking up Luxology lxp materials (that use jpgs as a stencil) surely we should be able to too use jpgs too...or are they simply using the sencil jpg as a transparency map and not an alpha mask? I cant look inside a lxp to see how they do it.

    I was hoping that I would not have resort to photoshop just to make a mask work. I take your point about the fuzzy nature of JPG files, but I would like to use a separate stencil file so that I can swap out the diffues map(s) without having to resort to a photoshop edit every time.
