There is a feature not supported by the 'on the fly' scene translation that would be really nice to get implemented. That's the 'projection parameters' in the texture locator attached to a texture.
Specifically, Octane ignores the U and V tile offset parameters, the horizontal and vertical wrap parameters, the horizontal and vertical repeat option parameters, and the UV rotation parameter. I make use of these quite a bit in my workflow and it would be really nice to see them supported.
