Alex Taylor Wrote:1. Are there any meta-commands which may not appear in the geometry sections? Is, for example, nesting !TEXMAP blocks in the same file supported?
NOFILE aborts the texture. I am proposing that STEP will also implicitly abort it. http://forums.ldraw.org/showthread.php?t...90#pid6390 If there are any other metas which have multiline "scope," they should not overlap a texture. I can't think of any at the moment though.
Nesting is supported according to the spec, but really, why would you want to? (I haven't implemented support for it yet.)
Quote:2. Is there any intention that the texture-image paths should support absolute filepaths? We do support these for type-1 lines (although that doesn't necessarily mean we need to for textures).
In the interest of cross-platform compatibility and relocation on the local filesystem, I would personally discourage the use of absolute paths. I don't actually support them for Type 1 lines myself.
Quote:3. Is it the case that you use either geometry1+geometry3 or geometry2, or can you use geometry2 in combination with either of the others?
geometry1 and geometry3 are mutually exclusive when drawing the file. Geometry2 (geometry not prefixed with !
will be displayed unconditionally, so yes, you may use it with either of the others.Quote:4. The description states that "If an END command given in a sub file stops the use of a texture specified in a calling file, then that texture will be restored to use when the sub file is exited." Does this mean that you can use "0 !TEXMAP END" in a file without it being preceded (in the same file) by an "0 !TEXMAP START"?
Don't do it!

P.S. I have no idea what the answer to your question about units is. I hope someone steps forward to answer.
