Houdini Engine for Unity » Heightfield conversion

I believe this to be a bug with the HEU_GeoSync not generating the HFs with the recent changes using corner sampling. Please attach a generated bgeo file if possible. I'll update this post when I fix it.

Which version of Houdini are you using? Also, is this through the PDG Asset Link, and loading the generated bgeo in Unity?

Do you have other Houdini Engine plugins running such as Unreal / Maya / Max plugin?
Does this only happen with the Steam version? You'll need to have Steam running always I believe, since it's providing the license.
I'll test it out a bit on my machine but please provide more info so we can narrow down the issue. Thanks.

Looks like its not working in the plugin probably due to the internal group attribute name. You can probably create a workaround using the regular Attribute Paint Sop for now. But please submit an RFE to our support team to add support for the Group Paint so you can track it. Thanks.

I tried out your hda. There should be an HEU_OutputAttributesStore component on the generated GameObject. This is different from the internal AttributesStore that the plugin uses for paint and editable nodes. See the screenshot.
PDG/TOPs » TOP Deadline updates in Houdini 18.0.399 (new MQ)

I'll be switching TOP Deadline scheduler to use the new MQ server feature permanently in 2 weeks. Please test it out before then in your farm setup so that we can deal with issues before then.
All your really need to do for testing is to set PDG_USE_PDGNET=1 in your environment before launching Houdini.
Also, the mqserver's high cpu usage issue has been fixed and will be available in tomorrow's daily build.
Thanks.

Houdini Engine for Unity » Bug with HDA "missing node"

Please submit a ticket to our support to improve the message when dependent HDAs are not found.
As for unity_houdini.env file, it only supports relative paths when using paths in Assets/ or Packages/. The reason being is that the plugin uses quite a few Unity APIs to load assets, which only work with relative paths from Assets/ and Packages/.
If you are using VCS, the recommended workflow is to use a mapping as described here:
https://www.sidefx.com/docs/unity/_environment.html#Environment_File_Paths [www.sidefx.com]
You can set a single path to your VCS root in unity_houdini.env:
HEU_ENVPATH_VSC_ROOT=C:\Dev\MyRepo
Then any assets loaded from C:\Dev\MyRepo will have <HEU_ENVPATH_VSC_ROOT> as part of their path. Then when using this asset on another computer, as long as it has HEU_ENVPATH_VSC_ROOT mapped in its local unity_houdini.env file, it will evaluate to the proper location.

You can edit the generated terrain with Unity terrain brushes, then use that as input for generating height field in Houdini. See https://www.sidefx.com/docs/unity/_terrain.html#Terrain_Input [www.sidefx.com]
You can also create a Input Node asset via the Houdini Engine menu in Unity (HoudiniEngine > New Input Asset). Then use a gameobject with Unity terrain component in the input field.

Houdini Engine for Unity » Unity terrain generation & input changes (Houdini 18.0.418)

For the Houdini Engine for Unity plugin, there have been significant changes to how Unity terrain is generation from height fields, and also how height fields are generated from Unity terrain (as input). Most notably, the plugin now relies on use of Corner sampling, instead of the default Center sampling, for height field nodes. It also requires height field size and grid spacing values to be exactly power of 2. This will produce the best match in terms of size when translating from Houdini height field into Unity terrain, and vice versa.
Please see update documentation here:
https://www.sidefx.com/docs/unity/_terrain.html#Terrain_Size [www.sidefx.com]
The plugin now ships with a sample HDA that lists the recommended parm values for height fields, located in:
Assets/Plugins/HoudiniEngineUnity/HDAs/TerrainGenerator.hda

Do you use Unity Collab or other similar auto-synchronized file system? There is an issue with Unity Collab where the plugin stores session data in a file called heu_session.txt in the Uniy project root folder, which gets synchronized with other machines and causes issues when the plugin tries to use the session data. Ignore this file if so: https://docs.unity3d.com/Manual/UnityCollaborateIgnoreFiles.html [docs.unity3d.com]
Otherwise, delete that file whenever you have issues. You can also try closing all sessions from HoudiniEngine > Session > Close All Sessions menu.
If you are still having problems, can you describe your setup? Anything out of the ordinary?

It is not finding the Houdini installation, which is usually located in C:/Program Files/Side Effects Software. When you install Houdini, it should add a registry entry which is then used to look up where Houdini is installed.
You can try the following to fix it:
You can try the following to fix it:
- Re-install Houdini, and the Unity plugin.
- Specify where Houdini is installed in the Unity plugin by going into the settings menu and specifying the location: HoudiniEngine > Plugin Settings > GENERAL > Override Houdini Install Path. Note that this is only available in Windows.

Best to submit an RFE through our support@sidefx.com email for something like this. Should be doable.

Are you using a different language locale for your OS than English? In some cases, if you are using specific languages such as Spanish which use comma (,) for decimals than dot (.), there is a .Net issue where it uses commas for Houdini curve points float values' instead of dots.
Otherwise, please submit a bug with an HDA which I can use to reproduce the issue.
