I've been trying to find a way to convince AGP to publish 3D building models (multipatch feature layers) to Portal, and I can't for the life of me get it to work properly. I get generic "failed to publish" errors, both in Pro and in AGIS Server Manager. I've tried importing from in-house KMZ files, and from internet-sourced/known-good KMZ files.
Has anyone else tried/had any luck publishing 3D building models to Portal?
