I suggest you check to see if this problem occurs in Houdini Console 'WindowsError: Error 234'.

If this problem arises, then you can refer to this article:

Hope you found that helpful

I had a similar problem in my project and I was struggling for a long time.Finally I gave in.
If any heightfield needs to be imported into unity from houdini,I will always use power of 2 starting at 64 to decide its size.

I think you may read following link for details especially chapter Terrain(Height Fields),hope it useful:

How about putting heightfield scatter and attribute wrangle after the merge node?
