I think there are two things we’re talking about here:
- Part/assembly info that is stored in the hierarchy - This is often used to store part names and various info, we support this across all CAD formats we load
- Metadata on parts - This is something that is specific to each part and is variable in the amount and type of information provided, supporting metadata is harder than #1, so we are working our way through the importers. With the upcoming 4.20 release, you’ll have metadata support for:
- SketchUp
- 3ds Max
- Rhino (possibly, working on it)
- Solidworks (bug is blocking us, hopefully we’ll fix)
- Inventor
- Catia
- NX
- Creo
Watch for Unreal Engine 4.20 previews in June timeframe. The code should be in there and you can report your findings.
