"description":"Experimental sampler node. Sampling alternates between A and B inputs until only one remains, starting with A. B steps run over a 2x2 grid, where 3/4's of the grid are copies of the original input latent. When the optional mask is used, the region outside the defined roi is copied from the original latent at the end of every step."
"description":"Given a set of lists, the node adjusts them so that when used as input to another node all the possible argument permutations are computed."
