Thanks all.
I had no idea you could create a flat image from an HDRI so went googling for that and came across the HDRI dome method Dwayne has just mentioned. There’s an amazing tutorial below. This comes at the problem slightly differently but essentially solves the problem and then some. In my use case the HDRI dome method is massive overkill but I’m curious and for me at the moment all this is completely new and a learning opportunity so I will go for it.

Given the way Blender 5 is going with presents for compositing etc. are things like this something that could be set-up and shared in future so you’d not have to create it and could simply update the HDRIs?
