Thanks userresu, that worked!
Now I can stream in my Houdini-generated ISMs as expected, thanks for that!
My problem now is that I get pretty bad stutters and frame rate drops as the tiles are streamed in at runtime…
I would have thought the assets would be streamed in asynchronously in the background and only drawn to screen once they are loaded, which you’d think wouldn’t cause stutters like that.
Have you found the same in your tests?
