Look at the pictures. The Buildig that is " a real one" is a ifc file i got from a customer to a project. This file have some colours when i import it to skechup and when importing to TBC. If i create my own objects in sketchup and export the as .ifc and the import them in TBC they are just grey. I have tried to give them just colours, textures, different layers and gave the layers different colours. Made a component, no component and a group. Does not matter, when i export my own objects from sketchup as a ifc to tbe the are just grey, how do i get them coloured?
