how to clone material with unique textures for multiple meshes

hi we are trying to make a dynamic material for our configurator , our 3d models have multiple slots of the same material(this are copies in blender spheres image) , currently our approach is declaring the material from blender we are able to change the material programmatically using the same functions that are in the visuallogic file

but now we want to have a single material of each type instead of copies and dynamically add as many unique clones we need for our models

i cant find any documentation on how to assign the “tex_image_bl_par_tex_idx0” index ,i believe this happens in the exporter

but when we change the material names , texture names and the “tex_image_bl_par_tex_idx0” property index it doesnt work
is there some additional documantation related to this? nothing pops in google when you search
tex_image_bl_par_tex_idx

and nodeTextures
seems to be propietary from verge 3d since is the only result in the web

here nodeTextures

it states this

You can use it to dynamically assign new textures to a material.

have someone have a solution for this ?
