Thanks for the info, Albert.

I've dabbled with Lua as it was once the scripting language of choice in Foundry's visual compositor Nuke. These days the Python API is far better than Lua as the Lua API is no longer maintained, so I don't come into contact with it so often.

A lot of content creation packages have moved away from Lua, which is a pity because Lua is nice and fast, which is super important when you've got 30,000 frames to render in a very short timeframe!
