Hey everyone!

I'm having an environment tool that manages a lot of data (heightfield generation, splatmap generation, terrain scatter), along with secondary tools that override params inside the environment tool.

I've noticed that with heightfield scatter (all using unity_instance attrib), the point data gets messy/wrong on overrides.

Is there a good practice for cleaning cached tool data in Unity ?

What I've tried so far to no effect is:

- Rebuild/Recook on all tools
- Deleting the tool outputs and rebuilding/recooking
- Having switches in the tool that swap between null and the actual tool output
- Using multiple versions of the HEngine - 18.0532, 18.5.388

What works:
-using “Reset all” and rehooking all data - but this is not a valid approach for production.

Have a good day!

Hey again,

I guess I can simplify the question further - is there a way to completely clear cached data from Heighfield Scatter in Unity, and regenerate it?

In a debug session, data is generated correctly, so I'm not sure what the issue is


Using Houdini 18.0.532
