Object types in Pixotope
You can easily convert 3D objects between these types by right-clicking them in the 3D view or the World Outliner and selecting the new type.
Convert
Foreground (default)
This is the default for all objects
It renders the object in front of the video
Translucent
It renders objects with translucency and possible refraction in front of the video without anti-aliasing the video
VS Floor
Sets the object to a state where VS compositing planes will always be in front. This avoids the risk of clipping e.g. when the VS compositing plane (with the talent feet on the ground) intersects with the floor object.
Opaque Holdout
A holdout object prevents any AR object from occluding the video backplate in the region where it is placed
This makes it appear that AR objects pass behind that section of the video backplate
The object itself is not rendered
Translucent Holdout
Same as Opaque Holdout, but controls the translucency using a gradient based material
This can be used to provide a feathered edge to a holdout object to soften the blending
The default material gives a radial gradient
Note: The selection of this type is only possible through the World Outliner
Right click the 3D object and click "Convert object to Translucent Holdout"
Create a copy of the "ARTranslucentHoldout" material in your project
Open the copied material
Add a "TextureCoordinate" and a "BreakOutFloat2Components" node and chain them into "Emissive Color" connector of the material
To continue the holdout, just put an "Opaque Holdout" next to it
For debugging
Go to "World Settings" → "Pixotope World"
Set the "Visualization Mode" to "Feathering Mask"
AR Shadow, Reflection & Light Catcher
It renders shadows and reflections that are cast onto this object
Can be illuminated by scene lights
The object itself is not rendered
These are typically floors or walls where you want to catch shadows and reflections to be composited on top of the video

AR Ambient Occlusion Excluder
In the area the volume covers, ambient occlusion will not be rendered
This can be used on intersecting shadow-catcher planes
AR Shadow Excluder
In the area the volume covers, no shadows are rendered
Used in conjunction with object trackers
Tracked Object Component
Links the object directly to an object tracker
Tracked Object Actor
Parents the object underneath an actor which is linked to an object tracker. This option allows offsetting your object relative to the object tracker.
