I'm trying to shortened the length of a transmapped hair by making a shader that can be applied. I normally shorten hairs with either a morph or by shortening the transparency map, but I wanted to do this with a shader. I tried what is shown below which moves the transparency map up and then covers the overlap at the bottom with a black band. I did this for both the texture map and the transparency map although it should only be required for the transparency map. This shader looks right in the preview windows but the render shows black hair where the transparency map should be making the image clear. I know this hair can be shorted by manipulating the transparency map because I did it by making a new map outside Poser and loading it in. It seems like the shader below should work too. I'm showing my ignorance here, but I think if this could be figured out, it could be easily applied to a lot of hairs and might help others too.

 

Thanks

Here's what I'm trying for and what the shader is giving me.

1.  Just plug the image map into diffuse, don't use the other thing.

2.  The modulus function is giving you problems.  Use multiply.

Looking forward to seeing your results.

I took your advice and cleared out the diffuse node. I changed the MODULUS function to MIN as the MUTIPLY made the preview look either white or black. There is some grey in the transparency map and MIN seemed to perserve it. The shader now looks like what I attached. I'll post a render in a minute.

Thanks

Here's the render

Looks good!  Could you try something shorter...say above the ear?

Looks very good. Well done!
