Hi. A little late to this party, but I had grabbed your free Studio Tools to learn from. Very nice looking, but the Object Manager and the Material window are completely blank! Is this a demo limitation? If it is, then it's pretty useless for learning. I've tried quitting and restarting r19 on Mac. Copied your objects and pasted into a new scene. Same thing. Renders beautifully.
Am I missing something here?
