I've been using 3.08 RC3 , OSX subscription version all day without a hitch, in fact I was going to post tonight to say it was the most stable release of Octane for c4d I've ever used!
Until an hour ago that is. I left my machine and went for dinner, and when I came back the live viewer wan't rendering properly anymore, just rendering a grey object on a black background. Very strange as everything has been working perfectly all day, including the blend materials.
Can I fix this? I've tried a restart of c4d r19 and my Mac, but still getting the same problem.
