Could you compatibility LibBlockAttributes?

I am aware of LBA, ive not looked too deeply at it, if I can add support in a way that is optinol then it might be a possiblity.

For TR->LBA, you could do something like what LBA does for Silk support:
https://github.com/AlexIIL/LibBlockAttributes/blob/0.5.x-1.14.x/src/main/java/alexiil/mc/lib/attributes/fluid/compat/silk/SilkFluidCompat.java

It doesn't have an official release, but I've heard of people mixing into LBA to fix it.

Another thing about fluid compat is that TR seems to use mB, while LBA uses droplets (1620).

Ah, I didnt know that was a thing. That seems easy enough. Does LBA have a 1.15 version?

LBA for 1.15.1 includes RC support.
