L1: Using ComfyUI, EASY basics - Comfy Academy

[Music] hello my friends how are you doing today I want to take you on a journey that is probably going to change your life we're going to have a lot of fun with comu ey and I'm going to show you why it is so capable and such an amazing tool I want you to imagine comfu ey as a canvas on which you doodle imagine yourself as a kid and you just draw out anything that is in your mind in your fantasy because comu ey is absolutely adaptable and open so in this video in this lesson we're going to talk about the basic functionality and how to understand it and create in an easy and fun way here we have a very simple workflow that is just creating this very nice image here you can see here there's different elements in here and we have here these lines that are connecting everything together so we're going to build that together but before we do that I'm going to show you how the interface itself works so let's start fresh here with this element you can move that around any way you want it on the screen here you have several controls in there and there might be something you don't have this is the manager and that is very important because here you can install all of the custom noes which are these little boxes we have just seen now this is very very easy to install you need to go to the GitHub page of the comi manager and then you want to scroll down a little bit and here you see this text line get clone and then the web address of the comi manager you want to select all of that and copy that then you're going to go into your comu ey Windows portable folder in there in the comu ey folder in there into the custom notes folder and when you're here you want to click up here in the address bar and type c DMD and hit enter this is going to open up your command window and here you'll simply paste what you copied before now that the text is in here you simply hit enter and wait for it to finish downloading should only take a couple of seconds after you've done that you can close the command window and you're going to click here in the comi windows portable folder again on run Nvidia Chu bat this is going to start comu ey for you and it's finishing the installation of the manager once you have that and you see this button here click on that and you will see this there's a lot of different buttons in here but they are all easy to understand there are three buttons that are very important for you one is the update all button and over here you might get a message that your comu eyes is outdated so you can click on that and wait for it to finish this will update comi and all of the custom nodes that you have installed the second one that is is very important for you is the install custom notes button here you can click on that and this is going to open up a list for you you can see on the right side when you already have installed noes you can either disable them or uninstall them disabling might be useful when they are conflicting with other custom nodes and of course you also have an install button so you can go and install it from here you don't even have to go to the GitHub page anymore now here are some of the note packs that I want to suggest to you one is called the comi impact pack the other one comi Inspire pack the efficiency notes for comi the ultimate SD upscale and then also the comi comy roll custom noes because these have some of the most used custom notes in them another thing you might want to do in here is to install models when you click on that you will have here a list of models now you will realize I that these are often not models that you are using for image generation itself for example up here this one for example is very good the 4X full hearty remak re the 4X Ultra sharp is also very good the 8X n mkd super scale 150,000g also very good and you can actually see on the left side by the type what it is you see here we have appscale inside face face rest or we have checkpoints we have embeddings and so on don't be too much concerned about that right now we don't need all of that at this moment before we get started you might want to do one more thing you will find the file extra model paths yamama example now you want to delete the dot example part at the end so it's becoming a yaml file and then you can open this up personally I'm using for that the notepad++ software but you can use any kind of text editor if you want to now if you already have for example automatic 1111 installed what you want to do is to set the base path to your automatic 1111 and in there to the web UI folder and then this will automatically link to these other folders here with the same structure so that means it loads all of the models that you have from automatic 1111 without having them as a duplicate on your hard drive you want to save that that and you can close all of that and then you can click in the menu here on refresh so it's loading all of the models or alternatively you can simply restart comi if you want to make sure that everything is loading correctly now where do we find the notes and where do we create that here is one advice I want to give you you can zoom in and out with your mouse wheel and when you do so you will realize there's a Very Thin Blue Line around here here now this is the starting area of your canvas so when you start to build make sure that everything is inside of that blue line you can go over the blue line but the core of your workflow should be inside of that blue rectangle here because next time you load your workflow it's loading that area of the workflow next of course we want to add some nodes in here the easiest way to do this is to double click on the canvas this is going to give you this search window here you can see you can scroll through all of the notes but even better you can type up here what you want to have for example K sampler this is for creating the images now we want to click on that and you can see this is adding the note for us so this is super simple and of course you need to know the name of the note but over time because you in most cases use the same notes you will remember the names over time or you can look them up in other workflows or ask in the Discord community ities for comi so in here you see we have some inputs here for the model positive prompt negative prompt the latent image which is the latent noise or anything you want to input as a latent image and then we have some settings here like the seat number you want to have here maybe randomizing the seat but you can also choose here from these pop- down menus for example have a fixed seat for every generation the same seat or increment or decrement increment means it goes up one number decrement means it goes down one number so you can see in these choices here we have different kind of data inputs here we have a pop down menu while here we have a number these are full numbers with no decimal point and down here for the CFG for example we do have numbers where you can have a decimal point in there so these are called floats and these are called integer numbers then you have a sampler in here you see it's a long list there's also a filter here where you can search for what you want to use and then below that you have a scheduler now this is something you don't have an automatic 1111 and this here actually gives you more freedom first of all you can see there's more schedulers in here but then also you can combine them any way you want so for example when you go in here and you have for example DPM Plus+ sde there is no caras version because you select this and then separately you select caras in here so this gives you more combination more abilities for experimentation below that we have the D noise that is similar to imageo image rendering so basically in any step in comu ey you can do image to image because you want to be more flexible you have a lot more ability inside of comu ey now how about these connection points here on the left side you will always have the inputs on the right side you will always have the outputs when you click and drag this is turning into one of these noodles or cables and you can let go of them and this will suggest to you something that might be useful to connect you can also click here on search to have the search window again if you want to search for something else another functionality that you have in here that is often very important is called the reroute now this gives you this little element here now the interesting thing let's move this over here is I can for example let's create a little bit more routes here and pretend that these are other notes that we are using for other things now let's say I have another case sampler down here let's simply copy that down here and I want to reconnect all of these to the second case sampler instead of the first one instead of going through all of them I can simply go now like this and I've switched everything so that is very useful but there's also a second important purpose for these reroute notes this can give you a lot more clarity in your workflow so let's say for example the cable runs like this and I have a note sitting here like that so this is going behind the note and it might get very confusing of what's actually happening so instead you can use these reroute noes to have this go around that and by that creating more clarity now there's also another reason for using these reroute nodes and that is to make your workflow cleaner and easier to understand so for example here you can see we have a lot of cables that go all over the place this can become very visually cluttered so instead we can use this reroute nowe to put it simply closer to it and by that we have only one cable going over here while the others simply go to the other nodes in a shorter path and this makes it much easier to understand now let's have another look at our starting note here because there's a lot more you can do with that you can see here on the left side we only have four different inputs and then all of these choices but what if you want to have for example the seat being controlled from the outside an example for that could be that you're using multiple case Samplers but you want to use the same seat in each of these case Samplers so for that what you could do here is rightclick and then down here you have a selection of convert seed to input so all of these controls can be converted to input so when I click on that you can see that now the seat is gone and I have an input for that so I can now create a seat note and connect that and as I said before here we have now two Cas Samplers that are fed by the same seed so when this is randomized it is creating one randomized number that then is going out to both of these case ampers so both of them always use the same seat number and that can be very helpful if you no longer need that input you can always rightclick again and then set this back so down here you see convert seat to videt so when you click on that this is removing the input and now you have here the setting again inside of the case sampler there's also more things you can do to customize your note for example you can change the title up here here for that right click go to title and then in here you can add something now I would suggest to you to keep the original name and then add something behind that for example let's say anime so this is for example the case sampler for the anime style that we want to create so that you know what kind of node it is and also what it is for this is important so you have Clarity over what is happening why you're using it especially when you come back to your workflow days or weeks later later another thing you can do to create more visual Clarity is to change the color of your notes so you right click again you can see here we have color and with that for example I can change this to green and you could for example switch all of your K Samplers over to Green so when you look at your workflow you know exactly where all of the K sampler nodes are another thing you can do to stay better organized is to create groups of noes for that you want to rightclick on the canvas and then select add group this will give you a colored box I often put this above my notes and then you can drag this out over all of the notes if you want you can make it a little bit shorter and then move the notes inside now this gives you an area that now combines all of them together so you can move them around together you can also bypass all of them together so you can right click here and then select bypass group notes everything is going to turn Violet this means means it's bypass it's not being used at the moment and you can undo that by again right clicking and then select set group notes to always like this now here's a fair warning this is a sticky area so that means if you move this area over any other note even if you only touch it a little bit it will become part of the note so you have to be a little bit careful where you're putting your groups and if something sticks to it you can simply move it out of the way and then it's outside of the group again also for any individual note you can also bypass them you do that by right clicking on the individual note and then select bypass and if you want to reactivate them again right click on the note and in this case also select bypass and this will activate them again this also works for notes inside of groups so you can turn off individual notes inside of a group thanks for watching and check out my next lesson oh you're still here so uh This is the End screen there's other stuff you can watch like this or that really cool and yeah I hope I see you soon uh leave a like if you haven't yet and well um yeah
