Is this compatible with upgrade mods like https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=820407959?

It seems that particular mod does work. I would venture to say that modules designed to work on vanilla refineries should work with these. It gets a bit trickier when it comes to small grid or modules that try and do something special.

The small grid ones will be tricky because I did not shrink the refineries down for small grid. They are the same size, components, and same effectiveness. I feel that shrinking, even if it is nerfed, creates an incentive to making the small grid ones over large grid ones instead of just allowing people who like to build with small grid ships to place this block on their grid. I only say that cause that's probably what I would do in my games. I'm open to suggestions on how to balance a shrunk version though.

And if they do anything with scripting, then who knows if they'll work.

Cool thanks for checking.

Interesting mod but, I would suggest removing platinum from the recipe or have an alternate recipe for planetside use. Platinum doesn't spawn on planets which is insanely silly.
