Run the command “NewFloatingViewport” to create a new floating perspective. This new window disappears for me whenever I open the V-Ray Asset Editor. Plugin version is v4.10.02 Nov 6 2019.
I have to click back somewhere in the other Rhino Viewports for the floating one to reappear.
It’s a bit problematic especially when setting up the camera resolution, and wanting to double-check with safe-frame.
Floating Rhino windows (e.g. not docked) will disappear once Rhino main window looses focus. V-Ray windows are external process windows and hence gain focus when you click and interact with them.
It is not strictly a V-Ray problem, it happens with a regular Rhino windows as well. Check this example:
As far as I know, Maxwell have their software as standalone and a bridge plugin.
If that is the case and you repeat the test above but clicking on the Maxwell window instead on the desktop will the undocked window disappear ?
Bellow I use notepad to simulate the situation. Clicking on notepad (or any other window on the system) will make Object Properties will disappear
