So long as Lumion can match (exactly) by name then loading the material file should be fine.
Are you using the Lumion exporter ArchiCAD to Lumion Bridge? Is it the beta or release version? ArchiCAD v16 or v17?
The first thing would be to double-check that there are matching material names in the two phase objects, as seen by Lumion. Easiest way is to just visually check material names by mouse-over a surface for phase 1 object and compare that the phase 2 has same.
You could also do a test by creating a simple object in ArchiCAD, such as a cube, assign a few materials to it same as for phase 1 and export/import to Lumion. Then test if the materials load to the cube without doing any changes to it in Lumion.
I assume you are not clicking on the material icons in the load materials list as that turns it off/un-selects it from being loaded?
If still not working, please send us the following:
1. The ArchiCAD models for each phase
2. The exported Collada DAE files and textures/texture sub-folder, for each phase
3. The Lumion scene with the two phase models, exported to LS4, and the MTT materials file. You can remove any other objects in the scene not relevant.

ps: Can you please add your Lumion v4 license to your forum Account, thanks.
