Octane Open Subdivision in properties tab for 2019 Octane Blender 2.8 doesn’t work with some modifiers. For example, a mesh that has Solidify, Screw, or Mask modifiers will not subdivide. Solidify and Screw work fine with OpenSubDiv in Octane Blender 2.79 versions.

See below images, which used the Solidify modifier.

Thanks for your report.
The Blender 2.8 involves some changes in mesh faces resolve and it should be the problem. We have made corresponding changes in OctaneBlender so it should be okay in the next build.

Cheers,
