I can't find a setting that lets be see a schematic underwater, the schematic is either a big blob of pink, or downright invisible. I've narrowed it down to 1 thing, the "EnableSchematicOverlay" option which turns it into the pink blob underwater when enabled and makes it invisible when disabled. Any ideas on how to fix this?

this no longer works, i tried to do those but it didn't work, the rebuild mode would work but there's no way I'm doing that

duplicate #21
also #5 is kinda related

Some things you can do currently: in Visuals turn off schematicOverlayTypeExtra, and turn on renderCollidingSchematicBlocks. You could also possibly use the Schematic Rebuild mode to fill all the empty areas in the schematic with water so that they would become the "correct block".

Other than that, there is a new option on my TODO list to ignore fluids as "extra blocks", allowing schematics to be placed submerged without the extra block overlay. And then a full block substitution system is also on my TODO list at some point. And then there is the overlayReducedInnerSides option in Visuals which is meant as a fix for #5, but it's currently still broken and doesn't work either at all or at least properly.

That seemed to work, and is usable now. Thanks for the help!
