Did you have a 3D pixel map installed?
No I was assuming that it would have a statement to render to 1D but I did not look at the code.
OK, in that case I think the error message is appropriate, it’s warning you the system doesn’t have a way to render properly.
Any chance the shuffle all mode could skip patterns which don’t have an appropriate render function?
Currently it freezes on the previous pattern for the timeslot.
