I much prefer having things built into max. Never understood why you have to export scene, then create shaders in a standalone, seems like doubling up the potential problems to me. OK there are a few benefits in standalone renderers, but drawbacks also.
I'm loving the direction c* has taken, think it's a very astute move workflow and business wise. I've tried indigo, maxwell, fry etc but the standalone app for shaders, lighting etc bit drives me nuts
