Hi there, I'm trying to create an erc1155 smart contract similar to the CloneX Vial contract.

> **[Mintvial | Address 0x348fc118bcc65a92dc033a951af153d14d945312 | Etherscan](https://etherscan.io/address/0x348fc118bcc65a92dc033a951af153d14d945312#code)**
>
> The Contract Address 0x348fc118bcc65a92dc033a951af153d14d945312 page allows users to view the source code, transactions, balances, and analytics for the contract address. Users can also interact and make transactions to the contract directly on...

There are two erc721 collections that are already launched that I would like to make the required tokens to mint an NFT of the new collection, using the erc1155.

What lines in the CloneX code should I change in order to achieve this? Thanks in advance!
