I just finished medium size project in Maxwell and have two suggestions for the plugin, but first little bit of background.
I had few 1000s objects in the scene and LightWave output window was slowing exporting process significantly. First frame was not so slow but (about 15 seconds) each consecutive was slower and slower, after 10 frames the export speed was fraction of what it should be (it took more than 12 minutes to export 10 frames).
What I did is - I fired 6 LightWave instances and I was exporting no more than 5 frames at the once. It would be much easier fr me if Maxwell plugin would work with LightWave frame ranges and steps from LightWave render window.
But the feature that would fix it would be option in the plugin to export quietly, or notify about errors only or maybe saved frames and errors only (like 3 options in the interface) - but - to be honest, check box - export quietly - would be more then enough, and very useful. Would that be possible?
I managed to export all 160 frames of the animation by constantly restarting exporting process, modifying frame range and starting it again - couple hours of unnecessary work.
