SDXLMixSampler 1.1

The node updated to accept loop:number rather total_steps:number

The total_steps would be calculated as mix_steps*loop

add final_only input to determine output multiple images or only the final loop image

If fina_only set to no, it would produce each loop image in output

SDXLMixSampler

The concept is to make one node to use both base+refiner like simple sampler.

Let me explains some parameter.

total_steps: total steps would run with this sampler. default is 20.

mixing_steps: total steps of one loop, loop = total_steps / mixing steps

base_steps_percentage: the percentage of base model's steps in each loop, the refiner would take the leftover

The whole pocess would only add_noise at the first base model sampling, other would disable_noise. The return_with_leftover_noise would be false at the last refiner node.

Why would I create this node? I was testing around generating text and I found it helps to generating text in multiple loop of the base+refiner process and I think it could done by 1 node.

All my custom_nodes would goto the flowing git page:
