Setting Required Inputs and Number of Inputs for HDA June 16, 2020, 6:16 p.m.

Hey y'all!

So I have a multi-part question:
  1. Is there a way to set the required inputs for the HDA? I have made an HDA that has a minimum num of inputs of 2 and maximum of 11. If any 2 of the inputs are filled, the HDA bakes and it results in an error state that requires a UE restart. I would like to set two inputs as the required inputs, and the others are optional. Is this possible?

  2. Next, is there a way to hide inputs depending on a parameter from the HDA? This would fix the issue from above, and make the tool cleaner for when artists use it in UE.


Setting Attribute Array for Each Iteration of For Loop May 4, 2020, 9:28 p.m.

Thank you very much for the information! Yeah, I think my main issue was I didn't fully understand what the For-Loop was doing. Now I have a much better understand of the inner workings of it and can therefore get the information that I am looking for much easier.

Found a solution. Creating a meta import node specified to “Fetch Feedback” rather than the default “Fetch Metadata” will return the result of the previous iteration. SUPER helpful.

Quite funny, I have been trying to solve this problem for a couple days, and I find the solution shortly after posting. But I hope if anyone else runs into this issue that this finds you well and its helpful.
