It took me several minutes before understand that the fourth pak object does not respond to the $4 & $5 variable.

So how can I specify the texcoord dynamically?

However I found the last DDG's tutorial really interesting, but it deals with only 3 variables. Working with a large set of variable seems to be a challenge since a message box accepts only 9 $1.

I tryed another solution, which is to set the command list in a text (ddg tutorial) but without success: the last texture coordinates still sleeps deeply ...

Where is the issue? Is it my GL syntaxe or any limitation in the software?

Solved, the texcoord has to be parse BEFORE the vertex spec.

However I don't understand why the first vertex is top-right and clockwise.
