Вариантивные ноды от ComfyUI_essentials (comfyui)

've added 2 experimental nodes to the ComfyUI Essentials useful to make small variations over the same subject. They are nothing "new", they use old techniques but they are very convenient to use.

1. The "Stochastic" Ksampler switches to a stochastic sampler mid-generation. It generally needs a variation strength of at least 0.5 but depends on the prompt and the checkpoint. It works better with karras and exponential schedulers. If the image looks burned you can try to use the scale cfg option that lowers the CFG in the second sampler.

2. The "Noise Injection" Ksampler, generates 2 base noises. One for the main generation one for the variations. It generally requires a very low variation strength, 0.1 should be fine or even less. With both by changing the variation seed you get more results on the same subject. The preview images have a batch of 4 images just to show the result, you don't need of course to generate 4 images each time.
