the optical realism &amp; physics node does not show up as an 'in this workflow' node inside comfyui manager, for some reason, so comfyui manager won't bring it up as a missing node to install. but you can search for 'optical realism' in the full list of nodes and install it that way.if you are getting an error (red outline) with the 'universal settings' subgraph and the 'ak base settings' node inside it, check to make sure that the sampler is one you have installed, i think i left the dpmpp_2_sde_heun sampler there and that's not one of the default ones, i don't think. switching to a different one on the list might fix this error.update! version 2.1 "willow"this small update adds comparison images to the steps tester and a selector for the number of test panels to run in the lora tester. it also updates the detailer tester to use sam3, which requires triton to be installed from the command line. if you need assistance please let me know!welcome to my test kitchen!this workflow will help you test loras, samplers, schedulers and steps on newly generated images, as well as luts, detailing and optical effects on a loaded image. i hope it's easy enough to use. the area to the right of the instructions node is the universal settings section. put in your models, prompts, seed randomization preference and image size preference. you will also want to put in a default sampler, scheduler and steps. note that the randomizer puts the same seed into every panel, to limit unwanted variation in the test. you can re-run your tests with a new universal seed or the same one, depending on how you set the randomizer node.the lora tester will use the sampler, schedule and steps that you've put here (as well as the base loras - the ones that you're not testing, the ones maybe you're testing against).the sampler tester will use the scheduler and steps you have in this universal setup, the scheduler tester will use the sampler and steps, and the steps tester will use the sampler and scheduler. this way you don't have to fiddle with any more settings than absolutely necessary.below this note is the activator panel. turn on the testing area you want to work with and then tweak the settings in that area.the lora tester lets you pick a lora (green panel) for the test. remember that any base lora in the universal settings will always be on. the starting strength is the minimum lora strength you want to test, and the strength step is how much you want to increase that strength across each preview.the remaining three image gen testers let you pick one of the three main attributes of sampling to vary for your test: sampler, scheduler or number of steps. whichever variables aren't being tested will be taken from the universal settings. for the variable you are testing, go to the top of each panel in the testing area and set it how you want. (the steps tester is the simplest: five panels, stepping from 2 to 10 along even numbers. you can change these, of course, but for most purposes they're the best range for z-image turbo anyway.)the lut, detailer and optical effect testers require a loaded image in the universal settings area. the detailer and optical effect testers have a lot of variables you can tweak, so make sure to isolate them one at a time.as always, if you have any questions, please ask, i will help if i can!--sft
