KSampler Overview

Image
Here we are going to have a brief overview in non techincal terms of the KSampler and what each option does.  This is what the KSampler looks like: The KSampler is what condenses the maths behind the scenes into a readable format for the VAE decode (or whatever the next step is). There are quite a few options here, and no real explanations, so here goes. Seed:                                         This is the random number the generator uses to create the images. Control_after_generate:      You can fix the seed so it doesnt move, increment or decrease the number by 1 after every generation, or randomize so it will be completly different every time.  I usually lock the seed if I am testing a model, or after I may have found a particular look that I like and dont want the seed changing and losing the image style. The changes are subtle, but th...

Basic Nodes and using Comfy UI

 What you see when you start Comfy UI are the basic building blocks of the interface. There are more complicated, more diverse, more niche case options, but we will come to those later. Lets take a look at what we have now. This is the basic screen that you will see when you click the load default button.     What does all this mean? Lets start from the left hand side:   Load Checkpoint:   This is the node that loads the Checkpoint, or model, that the ComfyUI engine will use to genereate images.  The three coloured dots on the left hand side are the outputs that this node uses. Model goes to KSampler, Clip goes in to the conditioning prompts, and the VAE is used to decode things. The colours will all match the corresponding inputs. Click the right arrow will pull up a menu with all the Checkpoints that you have installed. Clip Text Encode (Prompt): These nodes are the basic building blocks of ComfyUI. You tell the engine here what you want, in the top box...
