Vanilla flowing water blocks are invisible with BC installed #4044
BuildCraft version: 7.99.15 (compat. 7.99.14)
It's like it says on the tin. I was as surprised to come to this result as anyone else.
I tried disabling every single one of my other mods. After a couple hours of enabling/disabling mods and testing, I've found only Buildcraft to be the mod I need to enable to cause the issue, and disable to fix the issue.
It's very odd.
Obviously, it could be conflicting with another mod somehow, but I disabled anything even possibly water-related (Smoothwater, OptiFine, FoamFix Anarchy, TexFix, Dynamic Surroundings, Fancy Block Particles, etc) and BC still caused the issue when enabled.
Here's my mod list if it helps. https://pastebin.com/raw/sRZStcKF
BC does not mess with water or rendering in any way so there must be another mod involved as well
try making an instance where you ONLY have BC installed and no other mods, it shoudn't heapen there. Then you can add/remove mods with a binary search (but leaving BC in all the time) to find the other mod that is involved
Unsurprisingly, it is a conflict with Optifine C9. Optifine does have this tendency to break things.
If either Buildcraft or Optifine is enabled, water is fine. But with them both enabled, the rendering for flowing water breaks.
I tried quite a few setting changes in OF, but none seemed to restore flowing water. At least, the ones I could test. A good half of them ended up crashing the game. Bleh.
EDIT: Anisotrophic filtering needs to be on.
So, for clarity:
Buildcraft alone: No issue
How does this even happen. Wat.
