HDA AutoCook? Jan. 16, 2020, 1:58 p.m.


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?)

Update Input Landscape Data - Option Jan. 16, 2020, 1:52 p.m.


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…
