Sounds like you might have the "Keep world Transform" option on when you input your meshes? This is on by default. This retains the world position (in Unity) when we input it into Houdini. If you turn it off, I think that's what you're looking for.

You always need the HEU_HoudiniAsset component in order to cook it, but you can always press the "Keep output only" or bake the output to remove this afterwards.

Hi, your code looks like its correct if you are trying to just change a parameter. HEU_ParameterUtility is deprecated though, but should stil work.
The more recent way to change a parameter and recook the asset in H19 is:

Hi, we have a specific attribute for this. You can set i@unity_static = 1 to set the instance to static or not-static. You can also rely on the prefab's static flag by setting i@unity_use_instance_flags = 1. For other attributes, see https://www.sidefx.com/docs/unity/_attributes.html [www.sidefx.com]

Can you give an example HDA to investigate? Alternatively, you can try to change the default material to your own in HoudiniEngine > Plugin Settings > Default Terrain Material

Hi ! I am using the new option "Use output nodes" in my .hda wich works well. But when I bake it into a game object, I loose all my separate nodes, it result one game object. Is it possible to keep multiple output when I bake it ?
Thanks !
This looks like something we must have overlooked. I'll mark this as a RFE. For now, you can try just dragging the outputs out manually.

Adding the generated objects as Houdini input again could work. Another option would be to use the experimental NodeSync feature.

Hi, unfortunately, the editable curve workflow is no longer supported. However, if you would still like to use the legacy curve, you can still create the old curve::1.0 SOP and mark it editable and it should still be able to work in Unity.

To my understanding, you can still install SideFX Labs as part of the installer even if you have the apprentice license. After installing Labs, they should be able to instantiate it in Unity using the "Houdini Engine UU license", which is free.

Hi, I took a quick look at your HDA. If you close the curve, it should produce what you are expecting I believe. If this is not the case, let me know your exact reproduction steps.

This is actually an issue with Unity 2021.2.1f1. I updated the "Known bugs" page:

Houdini Engine for Unity » Cannot find any TOP nodes In Unit

We introduced TOP network filters starting Houdini 19 to align with the Unreal behaviour. Basically, in order for your node to appear in the list, you must prefix your node name with HE, or HE_OUT if you want it to automatically set the toggle to show results. You can modify the prefixes using the TOP node/output filter option, or disable it entirely.

Hi, sorry, I implemented another bug fix for Houdini 19.0.433. Now, all outputs should be display (instead of just the first one) when using output nodes.

Houdini Engine for Unity » Unity Instances & Tree Prototypes doesn't work together

Hi, if you could send me the HDA that you are using, I can take a look at your issue.
In the meantime, you can use output nodes to have multiple outputs (One using tree prototypes, and one using unity instances). Make sure you get the output node fix that prevents a few unnecessary duplicate outputs in Houdini 18.5.744.
