- Install NodeJS, Recommended version is 14.16.0
- Generator comes with already created layers, you will need your own layers if you want to create different images
$ npm install
If you plan to use different layers than the one already provided, you'll need to update the layers folder with your custom layers.
Inside of the settings folder, you will see a config.json file. You'll want to open it and edit the following values to your liking:
- layers (This will be a list of all your layers, order is important!)
- image_description (A description of your collection)
- image_location (IPFS link, don't worry about this until after you've uploaded the images to IPFS)
- image_count (How many images you want to generate)
- image_details (Adjust the width & height of the generated images)
$ node scripts/generateRarityConfig.js.
This will generate a rarity.json file inside of settings, you can then edit the weight of specific attributes. By default all layers have a equal weight of 10. By lowering this number you'll get increase the rarity.
In more detail, if you have 5 attributes each with a weight of 10, the total weight is 50. A random number is generated from 0 to the total weight, in this case 50. Let's say the random number is 28, it will cycle through each attribute subtracting the weight by the random number until the random number reaches less than or equal to 0. Once that happens, that attribute is selected.
$ node scripts/create.js
After generating the images, a build folder will appear with all your images. You'll want to take the image folder and upload to IPFS.
After uploading to IPFS, you'll want to update the IPFS link inside of config.json with a similar format to: ipfs://QmThdTBCR8DsnXMViDGC13EH9NughYzJrk7VjaAsRBmhX8
$ node scripts/regenerateMetadata.js
