Hi,

I make a Object HDA,that output transform to downstream obj node. I need set the HDA(subnet)'s Output Transform parameter to a inner null node. But it is grey and can't set default value in hda type editor. So I must explose it in hda ui and set it outside every time. How can change this parameter's default value?

Thanks for any tips!

I usually keep it hidden and set to desired value using OnCreated script session in HDA

It works! Thanks a lot!
