Possibility in a render element / mask ID, to be able to differentiate the different elements of a floor with a multimap with mesh element mode. Thank you
simplifying: being able to render a mask element render per map. to be able to separate the different types of maps by colors. If a floor consists of 5 wood textures, you can select each of the textures. I do not know if I explain myself very well
Use a CTexmap render element with a multimap using whatever colours you want to choose.
