Hey, I'm able to open Houdini Indie Limited-Commercial edition after buying it. That seems to be working.

I want to use Houdini with Unreal 4, but when I open my hda files in Unreal I get the following error: (Finished Instantiation with Errors: HAPI Error: Limmited commercial (Indie) assets not allowed with commercial licenses.

What steps do I take at this point in order to get my assets to cook? I'll do anything

Check your Houdini License Server and make sure you DO NOT have any full commercial licenses of Houdini installed. If you happen to have both Houdini Indie and commercial Houdini (base Houdini or Houdini FX), Houdini Engine will always choose the full commercial variant first.

To further explain, the full commercial licenses cannot be used to run limited-commercial licenses within Houdini Engine. That is, Houdini Engine will not “taint” when loading a lower commercial tier asset. Hence the error.
