I run both and they integrate pretty well. Recommended.

First you have to tell Vue where to find Poser and which SDK to use (Options, General tab). Then you can import Poser scnes into Vue, in various ways.

In the static way, all figures are taken as is but in the dynamic way you can repose everything, and actually do Pose Room through Vue: all the dials are there.

Second, you can choose whether to use the Vue materials handler (Poser materials are translated to proper Vue equivalents), or to use the Poser materials tree itself.

I'm not very good at the intricate details yet (like setting gamma in Poser and rendering in Vue, or the effects of Poser specifics like SSS), but the basics run pretty well.

Do note that when using the "dynamic" import and the Poser materials tree, you're actually running Poser and Vue together on the same scene when rendering. So you do need the RAM and CPU in your machine to handle that.I have not tried multiple Poser scenes in combination with massive Ecosystems yet, but I'm learning too.

Also do note that Vue is meant for outdoor vegetation rich scenes, and is not very good in portraying character close-ups. This is the reason for products like SkinVue, which improve on human skins when shooting close-ups.
PS: e-on recently had a Digital Environment Competition, with a special Characters section this year. The results might give you some impression of what can be done.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
