@Rune_Wangen: Hey, I’m trying to make sense of exporting HDA to UE4. I’ve got it working one time, with lots of messages I don’t understand, but now I’m stuck not being able to get Houdini to export a new parameter I added. For some reason the other ones seem locked now, and this one doesn’t show up in the asset properties.
@bob.w: I honestly don’t know anything about the UE4 side of things. But I’d double check that you’ve saved the HDA with the updated parameters, (re-imported in UE4 if that’s a thing). Double check that isn’t flagged as hidden, is enabled, and doesn’t have a conditional state
@Rune_Wangen: It seems to be a problem at the Houdini side, because the parameter I want to include is missing when I look at the asset properties in Houdini, but it’s present (but the only one not locked) when looking at the parameter interface for my node
@volantk: Now that it’s an HDA, are you still editing it in “Edit Parameter Interface” or are you in the “Type Properties” window?
@Rune_Wangen: I’ve added the new parameter in the parameter interface window, not in the type properties
(and it’s missing from type properties)
@volantk: That’s it then For HDAs you need to use Type Properties to actually make changes to the HDA. “Edit Parameter Interface” is just adding things to the instance of the node in the network, not to the underlying HDA, as far as I understand it.
Thanks, will try that
@bob.w: Okay, yeah that makes sense.
@Rune_Wangen: One more thing, I get this message all the time. I don’t really understand what it’s about.
@volantk: Have you removed the old leg_width parameter? It means that some nodes have had their parameters modified through Edit Parameter Interface
What does Show Details say?
@Rune_Wangen: I’m not sure if I explicitly did, but the param interface looks ‘default’ now, all are locked. I think I had this message the first time I exported the HDA as well (and the woman in the tutorial I followed also did, but she shrugged it off).
Show Details just pointed to the subnet that I’m using as my HDA
I reverted the layout, and all’s good now at least!
