To manipulate PDG from unity using the HAPI we base our code on the example in the documentation ( ), We read PDG events and never receive either a complete, error or warning event. Machine 4 : the process never finishes in either service or out of process mode. Machine 3 : the process finishes if the HDA Processor node is in “out of process” mode but not in “service” mode Machine 1 and 2 : the process finishes correctly The problem is that on two machine the process never finishes. We tested on 4 different machines and got 3 different results. This is a design constraint : we must export a lot of data the quickest possible any other approach is slower. The HDA Processor is setup to work in “service” mode. We figure our problem is largely related to TOP Nodes (making a no-pdg switch to export sequentially our data works) The problem is located inside the Exporter HDA. Making you reproduce the error is close to impossible since we use a very custom pipeline. Image Not Found to show the basic structure of everything, nothing too fancy. We have a process that uses an HDA structured like this: Everything tried inside Houdini Core worked, everytime, perfectly. Our problem is related ONLY to Houdini Engine. We figure the different version number should not affect the behavior: we make low level calls to Houdini Engine 5.0 regardless. The entire custom plugin is based on the “.cs” files we found with the base Unity plugin that accompanied Houdini 19.5.457. We do NOT use the provided plugin, only the DLL imports and we built a custom plugin with it. Our setup uses Houdini Engine HAPI with Unity. We then export the result to update the tiles. We load a "stamp" (Heightfield of a mountain) and blend it with the loaded tiles. We have an HDA "Stamp tool" that loads Heightfield tiles stored on disk. We design HDAs inside Houdini Core and we use them with Houdini Engine 5.0. We used both Windows 10 and 11, Houdini 19.5 on all machines. Top nodes tend to not cook/cook indefinetly. We are experiencing heavy issues using PDG/TOP nodes via Houdini Engine.
