Log file after tapping IPR with Custom OpenGL settings without render window attached.

I am unable to view the Custom OpenGL IPR in Houdini. I have no issue rendering via MPlay IPR but when I tap on IPR in the shelf with Custom OpenGL selected in options, I see the spinning beachball icon momentarily for mouse, then nothing. No window, no crash.

Eek! Just now seeing the test builds for OS X! Thanks

Any update on this? I've been using octane for C4D the last year and purchased Houdini license *assuming* it would work with 16 OS X. Should have tested demo first! Thanks.

Did I miss a post? Looking for R16 OS X Octane version with fix? Is that possible? Thanks! So glad I only downloaded demo of RF instead of purchasing it right way but I really can't remove RF from upcoming project
