ComfyUI How2 - Control Net

okay hello this is how to control net um where I teach how to control net without too much detail and messing around okay in order to do this you're going to need the default workflow you're going to need an load image node and an upscale node and the upscale is to set the source image to the same size as the empty latent image because it must be the same size and we are going to drag this out and we're going to add the node reprocesses Kenny is the default node that comes with comp UI and we're going to run a preview image and you can see what it does we run it really quickly you'll see it creates a bunch of lines for us to use and the reason we do that is when we load control net control add apply we need an image input and that image input has to be certain things based on what this control net model is so control net model loader and we can choose what it's once what it's looking for essentially to control with and so I'm going to be using the pre-trained Kenny model with this in order to make it apply to things it's simply using the the conditioning line so we plug the conditioning through it to a k sample this could be anywhere in your workflow and if we run it at one it should give us an approximation of the control knit lines as you can see they're pretty close now there's another option we have which is to run depth so if we run Midas depth approximation which is another preprocessor we can load this in it does require the model to work with it and then we plug the image in and then we make sure this model is set to a depth model and make sure your control net is uh the same kind of model as your main model or it is possibly not going to work sdxl it will throw errors you need sdxl control nets for that kind of thing okay and now if we apply this it should you has a similar image and it may be slightly lower quality actually it will take a while a bit longer to process with the depth image than with the line image with the candy one so as you can see it has approximated again generally speaking I find that the depth ones work in certain circumstances but in other circumstances like when there's fog and stuff like that you'll have trouble figuring out where things are in relation so this is how you set up control net hopefully it is of use to you thank you for watching
