Regarding changing CurveNodeData using C#: You probably need to recook the asset after changing the data. This can be done using HEU_HoudiniAsset.RequestCook(). Also, this was made easier to do in the Houdini 19 Unity plugin API update, where you can just call HEU_Curve::SetCurvePoint().
As for the issue where you are unable to set them in the inspector. I noticed this and I'll file it is a bug. You can still "drag" the values in the inspector though.

I recreated this problem with a much simpler set up that has one HDA that creates a sphere, another one that deforms it, and another one that instatiates points on the deformed sphere. I set the HDA processors, $PDG_DIR for HDA file and output name, cooked everything correctly in Houdini, and still the same problem in Unity.
Hi, it is possible that new features could have broken the old workflow. Can you send me your simpler HDA that reproduces the issue with some reproduction steps? I can take a closer look at it then.

Hi, I fixed an issue regarding duplicate geometry in Houdini 18.5.744. Can you try updating to that version using the daily builds and let me know if it works?

The video is using Houdini Session Sync (HoudiniEngine > SessionSync > Start Houdini). This feature allows you to work and debug through a live Houdini session. Cooks should work both ways then (If you modify Houdini, it should affect Unity, and vice versa)

When making HDAs for use in Unity, I've noticed that when merging in objects from Unity into Houdini Engine you often have to remove and re-add groups/objects in order to get changes and revisions to take effect when doing something like resetting a simulation.
This sounds like more like a bug. Does recooking also update the asset? If it doesn't, an example HDA would be nice.

1, There are 2 versions of codes to generate object geometries. One for Hda cook and the other for PDG cook. Is there plan to uniform them as one?
The PDG Asset link and Houdini Asset component will remain two separate scripts. However, in Houdini 19, if we detect that your HDA is a PDG asset, the PDGAssetLink will automatically be created.
OliverOliver
2, It would be nicer and faster if to generate object geometries through multi-threads. I see PDG Sync Bgeo is coded thread safe and using multi-threads already. but it only helps for syncing multiple bgeo files. But we are using tiled terrains(multiple volumes) in side one bgeo file. It would be better if it can use multi-threads to load one big bgeo file.
We're always looking into optimizing code to run faster and more efficiently. If you have an example problematic HDA, then I would love if you could let us examine it.
OliverOliver
3，We have added addtional post cook functions after the original cooking HDA. It took us some energy to collect the key info as paramaters for our additional processors which needs both the input and output of Houdini Cook. It would be better if Houdini Engine can provide the API for user to register new processors. And make sure they will be called at the right time with the right paramters.
I belive Houdini Engine would also be benifited because delvelopers will be able contribute easily by sharing the customized processors as unity packages indepedently.
In Houdini 19, the exposed API was refactored and taken a look at. It should be easy to change parameters or add a post cook funtion for example. If there is something about the API that you believe should be exposed or made easier, do let us know.

Hi, I just checked and surprisingly we don't have a way to import colliders in Unity out of the box. I'll add it as an RFE to add it as an option. As a workaround, just use a mesh input and then set it to a "collision_geo" group.

Hi, unfortunately, the Houdini Engine API doesn't support the concept of parenting right out of the box. What I recommend is to have the door and the locker as separate HDAs, bake to GameObject, and then perform a "Bake Update" when you want to update that object.

Hi, I believe importing Unity materials into Houdini is unsupported at this time (You can import materials from Houdini into Unity however). After using the polyreduce node, you should still have the unity_material attribute though, so it should show up in Unity if you use it as an output though.

For the first issue, I believe that it should have been fixed in Houdini 18.5.638. If the Steam build is not updating with the version, let me know.
For the second issue, the generated objects should take the flags of the HDA root. As you said, you can also add in the attributes manually to override it. In Houdini 18.5.610, I added an attribute where you can use the attribute "unity_use_instance_flags", which uses the flags of the unity_instance instead.
Let me know if this answered your questions.

I took a brief look at your example. I think you're mixing up details and trees? I attached both an example of trees using the unity_hf_tile attribute to instance different trees on different tiles. (simple_tree_prototype_split.hda)
Also, here's a simple example of using simple_hf_detail_prefab. (simple_hf_detail_prefab.hda)

I'm posting this to request for feedback regarding the Houdini Unity plugin. What is your workflow using the plugin? What part of the plugin do you like/dislike? What would you like to be changed? What new features would you like to see? Are there any important Unity-specific integrations that we don't have yet? How would you expect them to work?
For reference, the most recent larger features that we added are: Full HDRP/URP support, PBR materials, tilemap inputs, curve UX improvements, PDG output bake.
Examples of features in the Unreal plugin are: the official Unreal API, Niagara integration, LiveLink integration, Editable landscape layers, and upcoming KineFX / Chaos (GC) integrations.
Please post your comments, suggestions, or features below or as an RFE here https://www.sidefx.com/forum/topic/38188/ [www.sidefx.com] I'll make sure that your feedback and suggestions are heard. The more detail, the better

Hi, it's hard to say without the HDA, but it looks conceptually correct. Can you send the HDA for reference or file a bug report with the HDA attached?
