Houdini Main Changelogs

Houdini 18.0.513 Added several new expression functions for accessing work item data as a space separate string of values. The `pdgattribvals(name)` function can be used to get a space separate list of values in a specific attribute. The `pdginputvals(tag, localize)` and `pdgoutputvals(tag, localize)` do the same but are specific to input and output files respectively.

Added `pdginputsize(tag)` and `pdgoutputsize(tag)` expr functions, which can be used to query the number of input/output files on the active work item.

Houdini 18.0.513 Added several new PDG HScript functions which apply to the active work item when evaluated:

        * haspdgattrib -- checks if an attribute exists
        * pdgattriblist -- returns the space separated list of attribute names
        * pdgattribsize -- returns the size of the specified attribute
        * pdgattribtype -- returns the type of the specified attribute

The `pdgattribute` and `pdgattributes` functions have also been renamed to `pdgattrib` and `pdgattribs` respectively. The old function names will continue to work in the same way, but are deprecated.
