Hey guys,

so we're currently investigating if Houdini Engine works with our environment pipeline and after getting Houdini and testing around a bit I'm still left with a few questions. First of all I want to tell you the general idea of ours how we would like to use Houdini.
We want to setup the landscape and all actors which are scattered around within houdini. On top of that, we would have a few hdas which would load cities which are loaded from a file and as a whole placed on the landscape which then adjusts based on the needs. At last we would have hdas for roads, fences etc. This whole setup we would then like to sync directly UE4. Our designers could adjust the roads and fences without being required to have houdini up and an running. But afterwards, our TA would then sync this version of the map back to Houdini so they're both on par. So there's a few things which I didn't manage to achieve right away where I would like to know if I just failed.
- placing/instantiating an hda within Houdini (without and with a running session) and then get it into UE4 synced
- placing an hda in UE4 without a running session led into a empty actor
It would be much appreciated if someone could clarify these points!

Thanks,
Stefan
