Quick start guide and geometry alignment
Complex LED geometry
If the mesh is more complex it is required to
model it in a third party 3d program like
Blender, Maya or 3ds Max. Import the mesh
to the project and make sure the scaling is
correct.
Define the height, bottom edge height and 3
corner of the mesh and store them in Mesh
Builder as bottom left, bottom right and top
right. Three marker cones (anchors) should
be spawned. Move the real camera around
the space and make sure the cones are
stuck to the corners of the LED volume. If
they are not, adjust the horizontal
placement of the cones
(don’t
change the
height, which was found by measurement).
If the cones are still not bound to the
corners, verify the StarTracker alignment.
Now select the Static Mesh on
XRMaskBP
to
the one that was modelled beforehand. To
visualise the mask go to
MoSysCameraXR
and slide
Screen Alpha
to 1. It is the most
practical to get a pivot point on one of the
corners of the mesh. Make an empty actor,
place it under
MoSysStage
and snap its
position to the bottom left LED mesh. To do
it, click on the sphere gizmo of the empty
actor and press
v key
. It will then offer snap
points. Now parent the
XRMaskBP
to the
empty actor. Snap the empty actor to the
position of the bottom left cone or copy its
position. Use the pan rotation of the empty
actor to fit the mesh into the layout given by
the other two cones.
Verify and save the layout
Hide video and show grid on
Alignment
manager
. Move the real studio camera
around, while piloting it to see if the mask
covers the LED screen precisely and the
cones stay at the corners.
If they are not
you might have to verify ST alignment
and the lens tweaking.
Save the marker
cones’
positions with
Save
to file
button on Mesh builder, so it can be
retrieved later with nDisplay setup.
After save you can hit
Clear all
to remove
the cones. Control the blur on
mask’s
edges

details.
