Recently I purchased the OctaneRender plugin for MODO (OS X). Everything seems to work fine except that when i import a mesh with a few textures the don’t show up. It’s just a blank model. But al the materials and textures do show up in the shader tree. After reading the online manual it shoeld work after making a bunch of Octane overwrites an re-linking with nodes in the OctaneRender setup window in MODO. But no matter what I do, I can’t make it work.
For example this simple plant model; what do i have to do to make the alpha mask and the textures show up?

Thanks in advance!
