Hello ,
Thank you for your feedback.
We are working hard on the Solidworks importer as well as the other CAD formats, for example UE4.23 already introduced performances improvements regarding import time.
Suppressed features, as well as configuration/display states, are SW elements that are taking us a bit more time to fully support, and we’re also aware of the material issue in 4.23 that is going to be fixed with our 4.23.1 hotfix really soon.
In the mean time, if you find issues that you think should work please don’t hesitate to share the models with us so we can investigate.
Thanks,
Thomas
