Also, I'm unsure about using color 256 for the tyres in the shortcut files.
There was some discussion around using that color, but I don't think there
was any clear acceptance of it as an official "matte black".

Should I change these to "0" for black? :-\

Or we (that's an inclusive we, not just Paul, Steve and Franklin) should
make a decision on what we want to do with "rubber black".

There's definitely precedent for establishing a distinct color code that
will also inform material/texture settings for advanced renderings (ie,
having a "rubber black" separate from "regular black").  But it would also
make sense to add information to each part file, indicating the proper
material for that part.  LEGO also has made gray tyres, which are a
different 'color' than the standard gray.  It would be nice to just select
"gray" for the tire, and have the CAD software know that tires are matte
ruber, not shiny ABS.

Is this something that will only show when rendering? OR do you think that
the LCad software will eventually get that detailed?

Yes, just look at LDView... (http://home.san.rr.com/tcobbs/LDView/)


One problem with 256 is that MLCad does not have it available. It only
allows a selection of up to 255. Except you can make a "custom" color and
use it.

You apparently cannot select colors 256-511 using the mouse.
You'll have to type in the number. The number is initially shown in hexadecimal
notation, but you can enter it in both decimal (256) and hexadecimal (0x100).

Don't forget that black is not the only colour of Lego rubber parts.

THis can also be used for sloped parts textures:

Yes, I also recommend "0 TEXTURE xxx".
This works for *any* color, see http://home16.inet.tele.dk/hassing/l3p.html#extcol

And it works for slopes, where a section of the part definition has the
slope texture, but you don't know the color yet (only color 16).

MLCad should be able to automatically insert a "0 TEXTURE RUBBER" line above
and a "0 TEXTURE END" line after the line you change color/texture for.
