Hi,

Normally, this shouldn't happen, the plugin normally only recooks on demand.
(new asset instantiation, parameter/input change on an existing HDA)

This does sound like a bug to me, you should normally be able to have a landscape + curve inputs in a HDA without triggering a cook upon loading a level.

What version of UE4 / H are you using?
Is that only on a specific instance of the HDA? (if you use the same HDA with similar input on another level, does that trigger the same issue upon loading?)

Hi,

Update input landscape data does exactly what you think:
when feeding a landscape to an hda via a landscape input, it tells the plugin to try and update the input landscape instead of creating a new landscape actor.

For that to work, it requires that your HDA outputs a Heightfield that has the same X/Y resolution (number of points) than your input landscape. If that's not the case, then a new landscape will be created.

Unfortunately, that's correct, you cant use apprentice with Houdini Engine / UE4 plugin…
