Render-time procedurals based on the HoudiniProceduralAPI can now be ordered and chained together (e.g., the processed/generated output of one procedural can be used as the input to another)

21.0.143

Added parameters to the Python Processor that allow it to filter and ignore upstream failed dependencies. These options were already available via the pdg.NodeOptions configuration object in Python, but previously weren't promoted up to parameters on the Python Processor itself.

21.0.143

Added the ML Example Raw render node along with the ROP ML Example Raw Output geometry node. These nodes allow a data set consisting of packed examples to be written out more efficiently than before. Previously, such data sets would be written out using the ML Example Output node, which would temporarily store a serialized data set as geometry before actually writing it to disk. The new nodes write out the data set more directly and more efficiently, skipping the intermediate geometry representation. The ML Example Output node has been modified to use ROP ML Example Raw Output internally, allowing existing setups to benefit from this optimization without needing to modify them. ML Example Output remains fully compatible with its previous implementation.

21.0.142

Fixed kinefx.getPackedFolderPaths python method to return a sorted list of paths instead of returning entries directly from the unordered internal map. This also fixes the sort order of the RigTree when viewing packed folders.

21.0.142

Added an option to the Crowd Transition DOP to detach child agents from their parent agents after making a state transition. This can be used to more easily turn child agents into a full ragdoll which should no longer remain attached to the original parent agent.
