I know there is a big advantage to using a movable proxy setting when using a lot of heavy geometry instancing. But what about if you just want the geometry you are working on to appear "live" and automatically in the OctaneRender Viewport ?

The reason I ask, is that I always by default turn on "movable proxy" for everything in the scene, so I get live automatic updating of geometry, as I did in VRAY RT. But I am wondering if there is any performance hit by doing this globally, rather than just selecting a few items.

My BIGGEST question is why not just make geometry "LIVE" all the time in the viewport without having to refresh ?

Hi richardyarlett,
make a movable proxy object is very useful,
but making a very complex scene completely movableproxy can significantly reduce performance.
the answer to your biggest question is: yes, have it all "live" reduces the octane performance.
In C4D there is the option to automatically does all movableproxy.
I could send a request for developers to add this option in 3ds max too.
But is it so useful?

yes you are right. I tested a complex scene WITH and WITHOUT full proxys on, and it rendered 33% faster with no proxies than full proxies. So I guess if I can I will not enable them. Or disable them for final rendering.

- actually, I often times tend to select all objects and turne them into moveable proxy, just because I need a quick result, and then rarely come back to switch them off..
- I realize there is some performace hit, but I choose to ignore it or forget about it

- and I never disabled the "autupdate moveable proxy" checkbox in render setting - does that disable the proxy and the performance hit?

Also we have a "Auto detect" option for animation rendering. It try to detect which objects should be exported as movable and export others as static geometry. It's best for performance.
