Very excellent, Tim! Like everybody else, I am always amazed at the details
and quality of your project. Must become obsessive, isn't it? ;-)
I have used, and adapted, your slopetexture / wornwood macro for my own
needs in my windows_room adaptation of Tim Nikias'. For what it's worth,
here it is for use and comment for everybody.
Thomas

/* ADDED/CHANGED FEATURES (by Thomas de Groot):
The following parameters have been added by me:
- Polish: which controls the specular of the paint finish (instead of
phong).
- WoodType: which controls the type of wood.
- WearSharp: which controls the transition between wood and paint.
- Woodscale: which controls the size of the underlying wood texture.
- Paintscale: which controls the size of the wood+paint texture. You should
first
fix Paintscale before changing Woodscale, as the two are
linked together.

Good morning Chris and thank you for your comments. I am familiar with tree
nails and thought they were the rule. I based the iron rivets on this photo
of the USS Constitution whish is of the sme time period.
http://www.ussconstitution.navy.mil/Bowchasers.htm
I may have to do a little more investigation on this issue. So far I have
not been able to find clear images of the interior planking on the Niagara.
:)

Thanks for the encouragement Skip. I do know I am a bit crazy, but it is
very relaxing for me. I have a very stressful job and being able to lose
myself in this project has been wonderful.
I have in mind a web site dedicated to the project. I will post details in
the future, but I am currently working on written content.

Thomas!
I am pleased to see somebody using the worn wood macro...better yet,
improving on it. I love the changes you have made. I am seriously
considering using your changes in my own work. Thank you!
Me? Obsessive? Sometimes!

Looks good. You must try the wood's finish parameters and light.
Thomas, can you post a samplet for this macro?..
Hasan.

You are welcome! Often one builds a macro for a specific task, and then
changes are needed for another one. So it keeps growing and mutating. Very
fascinating.
I am sure you can yet again improve further on the macro :-)
btw, I wondered about the Norm parameter that is there in your original
macro, but without any use, are/were you considering uv_mapping at some
stage?

Thomas,
The Norm is reguired by the the slope function.

I am not sure I understand this. Because in your original example Norm did
not seem to be used.
Do you mean that Norm is what in the docs is called the <Direction> of
slope? That would make sense to me.

That works fine indeed....! I feel rather stupid :-(
The truth is that I didn't pay attention in the first place to what Norm was
for as it seemed not to be used in the macro. Didn't think further on a
little smarter level... :-)

Here is an example of what the macro does.
