Apply an image texture on a Cprism surface

[Raoul]

In the GDL script I want to use an image to apply it to a surface.

    DEFINE TEXTURE "PictTexture" "2.png", dimXPict, dimYPict, 1, 0

    DEFINE MATERIAL "pictmat"  21, 1.000000, 1.000000, 1.000000, 1.0, 0.5, 0.5, 0.000000, 3.0, 0, 1, 1, IND(TEXTURE, "PictTexture")

    SET MATERIAL "pictmat"

side-material ="pictmat" - the material results in a string

Next I want to put the material in the memory to apply it to a variable PRISM volume using PUT/USE/GET

For the PRISM Archicad demands a number instead of a string with PUT command in the memory.

PUT side_material

CPRISM_{4} top_material, bottom_material, side_material, mask,
n, h,
x1, y1, alpha1, s1, side_material,
...
xn, yn, alphan, sn, side_material

How can I replace the side_material...side_material variable from string ("pictmat") to a number?

What would be the solution ?

For that you use the "IND()" function, which you already used.

So it would be my_surf = ind(MATERIAL, "pictmat").
