Houdini HDA rebuilding landscape every time!

Hi guys!

So I’ve built a landscape HDA, this HDA has multiple parameters to control heightfields and grid resolution etc. Now, whenever I change parameters the landscape keeps cooking by itself over and over again. How can I turn it off and make sure it’s updating only the main input and not duplicate over each iteration.

literally having the same issue, took me a while to notice but my fps were dropping real fast. Did you find out if there’s a checkbox somewhere to avoid the rebuilding of the lands without getting rid of the one before?

It depends on how you build the HDA. If the parameters you are adjusting are before the landscape generation then it will recook when you adjust them in Unreal. If they are after, for example you make the landscape and then downstream have a parameter to scale it, it shouldn’t. You can also cache the landscape directly to the HDA for even faster loading.
