Texture specs are without an example - Willy Tschager - 2025-05-29

We need a fully working texture example (preferable a tile or something small) at the end of the specs:

https://www.ldraw.org/texmap-spec.html

showing how a code should look like. The explanation at the top is not enough. Please post something below.

have this code

Code:
!TEXMAP START PLANAR -36.1299 0 36.1299 36.1299 0 36.1299 -36.1299 0 -36.1299 32533p234.png

!: 1 16 0 0 0 1 0 0 0 1 0 0 0 1 s\32505s01.dat

!: 1 16 0 0 0 -1 0 0 0 1 0 0 0 1 s\32505s01.dat

!: 1 16 0 0 0 1 0 0 0 1 0 0 0 1 s\32505s02.dat

!TEXMAP END

will this work as an example

Additionally a link to the example for the mpd spec could be added. That one includes an embedded image.

I think more cross references in the spec/documentation could help in general.

This is one of the !TEXMAP test files from LDPE:

You don't have to have the fallback if the non-fallback and fallback geometry are identical. It can just be:

Code:
!TEXMAP START PLANAR 0 0 0 10 0 0 0 10 0 checker.png

16 0 0 0 10 0 0 10 10 0 0 10 0

!TEXMAP END

Note the lack of "0 !:"

Actually in the above case it could be shorted even further to:

Code:
0 !TEXMAP NEXT PLANAR 0 0 0 10 0 0 0 10 0 checker.png

4 16 0 0 0 10 0 0 10 10 0 0 10 0
