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...
Whoo Hoo! It works but,
I am using a pattern map and a mask map for the base texture.
If I use the mask as an alpha mask in the pattern map it takes forever to render. (15 min)
If I use the same mask in as a transparency map it is much quicker. (2 min)
In both cases I'm getting a wierd specular highlight on my materials. I've seen this before on mask/transparency. I expect this to happen using a tranparency mask, but surely if some thing is masked there should be no specular highlight in the masked areas? Do I need to set my specular map = mask map?
Yes you do...
Specular map = transparency map. (2 min)
Robert,
Also if you switch on transparent background in the map edtior for your leaf texture we will output a stencil mask for that texture which is better than a transparency map for this as where the pixels are the background colour the material/geometry for that pixel is ignored.

I'm using two map files here (downloaded from the luxology texture Ivy). I had to inver the black and white mask to use as an alpha map.
I'm really not sure what the avantaged are of alpha vs transparency.
Either I use the mask as a transparency map which seems to give a quicker render,
or I use it as a Alpha "Pattern" map in which case there is no need to hit "Transparent back ground" (or is there?) but this is quite slow and doesn't get rid of the specular highlights in the invisible areas.
