GDL COOR{3} with PLACEGROUP command

[concepsys]

Hello,

I am creating a geometry by creating a GROUP.

Inside this group I have for..next loop that CALLs a geometry.

I want to apply a texture over this construction, but I can't. No matter what I try the texture (that I placed in the beginning of the GROUP is still and won’t change.

I tried using COOR{3} inside the group (between GROUP and ENDGROUP commands)

I tried after ENDGROUP command

I tried after PLACEGROUP command

but cant control the texture.

How can I solve this?

(By the way, I am working in Archicad 22 to make sure they become compatible with all later Archicad/GDL versions. Could this be a problem that has been solved on a later version?).

Thanks in advance.

Sorry for my late reply. I hat to deal with other projects and only yesterday got back to this one.

I'd like to thank all the help that I got on this theme, specially from @runxel that took a lot of his time to help me with valid yet more complex solution. Your GDL knowledge is very impressive and if you don't mind I may bother you again in the future.

I marked Péter Baksa's post as the solution because in fact, althoug my inital question was itself more complicated than needed, his solution was the one that I ended up using, just because it was an easy solution for my actual problem, allowing to keep the project centralized in a file that calls simple macros and allows an easier way to manage diferent unique randomly shaded elements through different composition geometries. The result was great!

Again, Thank you all.
