This is a NFT generator which takes a set of layers and combines in a single NFT image with metadata files that follows opensea specifications.
Inside images folder, you will find some images as demonstration. You can remove these images and add yours. Please notice the images has _r and _sr, these abbreviations are used to specify the rarity level of the image.
Just run node generator and you will find your generated images inside collection/images and the metadata files inside collection/metadata. Don't worry about the {{IPFS_URL}} which you will find in your JSON files. You can replace then by running our utility script.
Please do not run node generator before replacing the IPFS metadata urls. You need to update first your images to ipfs or any other ipfs gatway in order to get your ipfs hash. An easy gateway to quick upload your images is Pinata
Notice the JSON files will have {{IPFS_URL}}. Please go to config/base.js and paste your ipfs hash on the YOUR_IPFS_HASH value.
You can just replace them by running node ./utils/index url-updater.
After that you are done! Congratulations, you have your NFTs with metadata that follows opensea specifications
