Hi, I'm following this: https://www.sidefx.com/docs/unity/_attributes.html#AttributesStore [www.sidefx.com] documentation to transfer some integer attributes to Unity, but no data arrives in Unity.
I have tried multiple different attributes and tried to replicate the version in the documentation 1:1, but I can't get it to work.
What am I missing? Can anyone confirm this working or maybe provide a working example file?

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.

Hi Seelan,

I do have this component, but it does not seem to contain any data at all (see attached image).
I'm on Unity 2020.1.0b5

Ah I see the problem. Since it stored as dictionary, on code domain reload, its being cleared. This will be fixed in next daily build (Houdini 18.0.472).

I downloaded this HDA as well, but cannot get it to cook with an HEU_OutputAttributesStore component either. Has the issue been resolved yet?

Did you try with Houdini 18.0.472 or newer?
