No idea what caused it but after playing with some setting and changing kernals a few times the window became unresponsive and I got a gpu 'failed' message where the memory use is shown below the 3d view.
Never had that before. When I looked at the memory use graphic in the preferences it was completely full.
I was amazed to see the octane process was taking maybe 600mb.
Actually all the memory used by each attribute might have about in the right proportion but was many times what should be. Serious memory leak or something?
