Thank you Thomas, I think this should help us with the transition. I recognize Archvision’s content & software are buggy and have lagged behind the industry for years now, but they were the first in Revit, so there are some entrenched workflows that will need some time to adjust.
Since I just got a renewal notice for RPC, are you saying that Enscape 2.8 will continue to support it, but 2.9 and beyond it won’t?
Enscape Team,
We are at the point of deciding whether will renew subscription with ArchVision.
We want to get a confirmation whether it is true that strating from 2.9 onwards ArchVision will no longer be supported by Enscape. Thanks.
ArchiVision content should still be supported even with Enscape 2.9 - @BSG and @joeykeys , could you imagine eventually unsubscribing from ArchVision, or is a corresponding Enscape compatibility a must for you? If so, can you perhaps let me know why? 
Of course, because you still want to use objects provided by ArchVision, so I reckon you can’t find these objects in our Asset Library yet? Perhaps you have some specific requests regarding what we could add to our Asset Library so that I can forward these accordingly?
I think the breakup is a lose lose for both parties, good content with good real time rendering is a win win for everybody. The work arounds punish the user in loss of productivity. Find the middle ground. Buy each others stocks if you have too.
