I've made a building generator for a school project as well as an portfolio item. when i try to import it in to Unity however i get the following message:



I cant seem to find any undefined nodes myself, nor do i really know what it means for a node to be undefined. Any help would be greatly appreciated.

I have same issue. While I was able to open HDA in unity but asset parameters are not working in Houdini Engine for Unity. The error mentioned above is appearing every time I rebuild the HDA.

I am also having this issue. Can someone provide a solution?

Did anyone found a solution on this ?
