}
```

Experimental method to allow future-proofing for the iNFT standard. Gets the render token URI for a given tokenId and owner, along with parameters.

function setTokenURI(uint fnftId, string memory _uri) external override {
    uri = _uri;
}
```

Sets the token URI for a given fnftId to the passed in \_uri.

### setRenderTokenURI

```
function setRenderTokenURI(
    uint tokenID,
    string memory baseRenderURI
