Hello zidekk2,
Regarding the access to CAD import, I forgot that we do not share the third party SDKs needed to build some of the necessary modules (Alias, CAD, Rhino, …) in the git version. So it is normal you do not get those.
The master branch is pointing to our main UE4 branch that is not developed anymore.
You will want to use either:
- 4.27: that is ahead of release (4.27) where fixes are added
- ue5-main: the main branch for UE5 development.
