Batch export of tiff files from a folder of Dorico files - LUA?

Hello there,
I need to batch export 300 dpi tiffs from a folder of Dorico 3 files. I recognise the LUA plug in and scripting is still short on documentation or full implementation but I wondered if anyone had had any experience of doing this either with LUA or can recommend a quality Windows 10 macro recorder that might be able to accomplish the same result.

Many thanks

I’m afraid I’m not sure there’s a good way for you to automate this yourself, but it might be possible for us to do it if you wanted to package up all your Dorico projects and send them to me via WeTransfer or a similar service. We have a command line tool that might be able to do this reasonably automatically.
