Export to Lumion

Hi guys, I have multiple panels in my model, the ones having the same material are kept in the same layer which a unique material for itself. But when I export the file to lumion, each panel reads as a different material, since I have more than a hundred panels, this is very problematic. Please let me know if you have any idea to fix this problem. I’m using Collada or .dae format.

Hello - what file format are you using to export?
