Youa re welcome :-)

Ah yes. I think that I have noticed that as a side effect indeed.

Great! Looking forward to it!

- I am not sure if a diffuse 1 is such a good idea. I prefer 0.6, or 0.8 
when using an image map, like in the current version .
- Why a *double* declare for the pigment? It seems to me that only one 
should be enough, either PR_MAP_DIFFUSE or PF (well, I see some consistency 
now with the other pigments)

- Neat! I like this. I believe that this will work much better than the 
current, rather crude, texture layering.

- OK. I see the change from Clear. Certainly works better.

- This is a difficult one. I need to test this to see how it works. My first 
impression is that it looks fine however.

- Same as above.

- I think you put the wrong example file here. No normal visible.


Looking good overall. I am thrilled!
