I don't know what I'm doing wrong. I setup a scene with a couple of primitives. Do a simple animation. Create a light, a camera and a render node. Invoke Mantra. And then I get a black screen and the objects get this zebra pattern… :cry:
How do you get at Mantra? I have this problem when I render via the camera icon in the viewport. One wrong click can mess everything up, I have even lost work that way. It's a bug of some sort.
I access Mantra from the Menu Bar: >>Render>Create Render Node After I do this I can't do a quick render via the icon on the viewport, just as you mentioned. The only option that seems to work is, once you have everything ready, just render to a file. But it sure sucks having no quick render…
