3dsmax Live Link and Regular Vray GPU Render Window Switching

[jujubee]

Testing a scene in Max.
1. Render regular GPU via Max in VFB works fine.
2. Close out of VFB.
3. Switch to Vantage and use Live Link. Works Fine.
4. Close out of Vantage and switch back to VRay GPU VFB.
5. VFB no longer processes any renderings.

Here is the VFB Error Log:

Seems like there's some licensing issue which can happen when switching/closing out of Vantage Live Link back to Max.
It appears to be Switching off using local host in the Distributing Render rollout of the Render settings and not switching it back.
I can get it working again by manually checking that local host checkbox.

Live link works through the V-Ray DR protocol. It temporarily changes the DR settings. It should restore the old settings if you stop the live link by pressing the link button a second time. Otherwise if you only close the Vantage window, the live link session would still be running from Max's point of view and would resume rendering as soon as you start Vantage again.
