Thanks,
i hope, with the quick preview, you mean the render region. If this is correct, there is a bug.
The shaders must be replaced, yes. thats because you can use compounds.
The old shaders had some inputs, which were not the real parameters i had used for the Octane shaders.
It would be to complicated to switch it across a shader compound. For now all inputs are real inputs, which are also used to generate the shader nodes.
This can also be the problem with the material preview.
Try to close Softimage, start it again, use a clear scene and make some materials, i think then the shaderball is working.
The problem here, Softimage seems to save some layouts and/or parameters of the shaders with the scene.
