I am using RVT 2024.2 and Twinmotion 2024.1.
I am exporting datasmith files from Revit, and re-importing them in TM. Sometimes these are different versions (design options) in RVT but the materials in RVT are consistent. E
Frustratingly, each time I re-import the datasmith file, the materials change. Glass can become air or insulation, my concrete columns become glass, grass becomes vapour barrier. Its like TM gets confused and mixes up the RVT materials. This doesn’t only affect the objects that change with each design option, even objects which are unchanged when moving from one import to the next seem to get mixed up.
I have tried collapsing all, applying materials by ‘apply to object’ instead of ‘replace material’.
Any help would be appreciated.
