hou.RopNode.inputDependencies method
Returns the input dependencies of the ROP node, which are the ROPs and frames that need to be be rendered prior to rendering the ROP node.
inputDependencies(self) → tuple of RopNode and float tuple tuples
The input ROPs upon which this one is dependent are returned as a tuple of ROP nodes, and a corresponding tuple of float tuples is returned giving the frames that need to be rendered for each ROP in the first tuple.
Replaces: render
