LodGroupCreate
When pointed at a location, the children are assigned a level of detail (LOD) range for each node input. The
parameters of the node directly correspond to the PRMan values and are based on screen area. This means when
rendering smaller test images, the resulting output is different to full renders as the calculation of the bounding box
mapped to the screen is different. For more on how to get the most out of these parameters, please review the
PRMan documentation.
Each node input that requires an LOD range must be added as an additional input using the inputs > Add > Add
Input menu option.
Control (UI) Default Value Function
groupName lod_group The name of the level-of-detail
group location that is created at
the hierarchyTargetLocation.
hierarchyTargetLocation /root/world/geo The Scene Graph location where
the level-of-detail group is
placed. Each node input creates a
level-of-detail location below this
location which stores the
lodRange attributes for that
input.
inputs N/A The parameter grouping for the
node inputs.
