I signed up, but the second question is different on your sign up form than here in the forum.
Either way, we are just (currently) two people in a quite large industrial design firm who have been using Unity for two years for various small VR projects. We are about to begin a potentially much larger project now and have switched to Unreal Studio Enterprise with Datasmith. This means that we’re new at this and also have different requirements than traditional gaming studios, in that we deal with very complex imported CAD models, containing thousands of parts, meaning our scenes are quite large and complex before we begin to optimize them.
The blueprint synching for the January early access looks like something we would really like to test, because we will probably not go beyond having a scene or two and some blueprints to control it in VR.
