I'm in the same case... so many workarounds (that are not garantee to work) that It's not possible to rely on octane for any job.
I'm using both Lightwave and Modo. Both exporters are bugged. For instance, I have a scene with badly unsmoothed meshes in Octane. I do the trick (re-exporting only the obj from Modo, overwriting the previously mesh export that was done when exporting the scene for rendering) Now my meshes are smoothed when toggeling the Smooth boolean BUT I've lost the UV on both the floor and the wire mesh on the balconee. What I mean is , what worked previously with the first export stops working when fixing the smoothing, It's like there is always something that doesn't work. I'm not even talking about the animation.
Could we get a simple, working exporter for Modo or/and lightwave?
Would It be possible to have In Octane a Smooting slider or input to specify the degree of smoothing needed?
I love Octane, It's better to me than Arion or similar concurrent softs, but what use It is to me if I can't actualy use It?
