Hi,I'm working with a HDA actor in UE4. I'd like to save/load my settled input parameters so that I don't need to set them again when I reimport the HDA.“Doing parameters” in “Houdini Asset” works well but it only supports “Houdini Parameters”, how to make it accessible to “Houdini Inputs”?

Hi,

Parameters and inputs are saved on the HoudiniAssetComponent that;s in your level.
They should be preserved, even after a reimport/rebuild of the source HoudiniAsset, but unfortunately, you cannot dump them to a file for later use.

Alternatively, if you want to save a “preset” of your HDA, and are using the v2 plugin, then you can simply create a BP Actor, add a Houdini Asset Component, point it to your HDA, then set your inputs/parameters on the HAC.
The choice of input types is however, currently limited to Geo IN in the current beta.
