I installed that neat OTL lately, but it seems that I'm having the exact same problem with the specular as user ajz3d described! Does anyone know how to do the custom installation (because “Extra Files” tab does not contain the needed information..) ?
I shot the author a tweet asking about this and apparently the later, current versions of the asset no longer need this step. It just works without any additional file install. He just never came back to the forum after implementing this change. Reflections work fine, you just have to “unlearn” the old, bad convention of considering “spec” and “reflect” as two different properties.
I also ran into the problem with errors adding this asset to an existing or new .hip file and the only solution that I've found to avoiding any errors is to select the option to “Install OTL Only” from the pop-up menu in the Asset Browser and then add it from the “Digital Assets” sub-menu in the SHOP network. Double clicking in the Asset Browser is broken. “Add Asset to Scene” is broken.
That's not a problem with this asset though, it's a problem with the Asset Browser itself. If I use any other method to add an Orbolt asset to a .hip file other than “Install OTL Only” and then drop the tile from within an appropriate editor it's a sometimes works, often not deal and this behavior is consistent across two separate, fresh installs of Houdini Indie (perhaps its more problematic in Indie/Apprentice installs).
Back before Thanksgiving I informed Orbolt of this problem and one of their guys was able to at least partially replicate the issue on his end but I was given no indication as to what it might be from or any additional solution and haven't heard anything more. I'm just happy that at least one way of using it seems to be reliable.
