Release 8 - new features, cleanup and documentation

What's new in Release 8

• The default is ONE camera. If you need TWO cameras read this to see how to get the old setup back.
• The default is VIVE trackers using LiveLink. If you need to get in a different kind of tracking read this document.
• The telemetry viewer for debugging tracker problems has it's own document, read it here
• There is a new tool for measuring your studio read the document here
• ActorTransformTelemetry replaces ALL the other telemetry sending blueprints. See this document for datails on how to use it.
• ActorTransformTelemetry runs "post physics tick" so all actors are updated before it sends their positions.
• LiveLinkTracker supports trackers that send relative data. Select tracker type "relative tracker" and supply "Relative Tracker Offset" to align tracking to the coordinate system of the Talent Mark.
• Autorig no longer displays a vive puck at the top. This is unnessary because the LiveLinkTracker draws the tracker mesh.
• Autorig sizes it's rods to the exact rig measurements you enter so they don't stick out.
• Autorig's rods are now colored to match unreal conventions for x, y, z
• Added ThinAxis actor, makes it easier to see the orign of smaller objects, just attach it.
• Vive controller buttons work when using livelink. They still need to be mapped in the Vive control panel and the Unreal 3d window has to have focus.
• Added RecordMeasurements a way to measure your studio using the VIVE controllers/trackers
• Added MeasurementMarker actor, displays an axis marker and current position, used by RecordMeasurements
• The default map is now SINGLE CAMERA.
• Flying logo is now self contained in one actor. Epic fixed a bug that prevented this in earlier versions
• Flying logo can be started by pressing 9
• Added categories for some actor variables to organize them, also added some tooltips for them and set limits on variables that needed them.

Bug Fixes

• Fixed desk, floor and wall matte actors so the size parameters work. Note there is nothing special about these, they are just simple shapes with some blueprint code to make resizing them easier. They must be added to Window->Layers->GarbageMatte to be recognized as part of the matte.
• Fixed measuring grid so the display/don't display menu works in editor as well as play mode

Changes you won't notice unless you have customized my blueprints

These are mostly changes to make the whole setup work better, simplify the internals and make everything more consistant.

• Renamed media player assets that go with the Flying Screen actor
• Renamed all the parts of the AJA media bundles in a consistant way.
• Renamed Autorig "entrance pupil" transform to "output" for consistancy with other rigs.
• Removed "Telemetry Order" in all tracker actors, no longer needed.
• MotionControllerTracker, DelayedOutput has been renamed to "Output" for consistancy with LiveLinkTracker
• All tracker actors use a more efficient way of setting the correct mesh for the tracker.
