Thanks! The screw in bone part does not sound fun at all… I got lucky, displaced oblique fracture to the 5th metatarsal that didn’t need surgery.
Anyways, have you been about to figure out the issue with HDA changes triggering re-import?
I was thinking this part from the link might have been related but on second glance, probably not
“By default, the Houdini Plugin creates a Landscape Edit Layer during cooking, which will cause the entire landscape and its loaded streaming proxies to be marked as dirty (if loaded). This can be disabled in the Houdini Asset Component by unchecking Temp Landscape Layers and will cause the HDA to cook directly to the baked layer. When working with World Partition levels is may be preferable to create these baked layers once, save them, and then iterate on small sections without recreating the layers.”
I was hoping someone else who knew more would have a definitive answer for you but maybe someone will see it with this reply bump.
