May we have a section that contains a list of node types that may be added to the editor? When I first got my hand on Unigine a few months ago, I tried adding a PlayerPersecutor class to the editor, which is of course, not possible, leading to an application crash. My workaround back then was to add a NodeDummy whose position and rotation is set from the PlayerPersecutor instance since I only needed to see if the camera goes where I want it to. I'm in the process of upgrading my Unigine copy which now allows a PlayerPersecutor instance to be added to the editor. Thanks.
