(Render) Materials in IFC (?)

zoomerzoomer
in General

I do not quite get it ....

Is there some Image Texture exchange Support in IFC ?
(from which version on or planned ?)

I see IFC material Properties in Blender BIM but not much content.
Could there be any Material Definitions for Rendering in IFC, beside just dead info data and Color ?

Is Object Color transferred, only starting with IFC version 4 ?

My biggest Problem with IFC exchange, from BIM/CAD to a 3D App e.g. Blender.
(Or even from BIM to BIM)
I do get Materials in since a few years (?) but in some cases these duplicated many times.
(For certain Objects only (?))
This does not really help for Visualization purposes.

Are there any standards for Material definition/control in IFC or any workarounds onthe
importing App's side ?
