Hey, I am using the Forge 1057 src for 1.7.2 (the latest version) to write my mod - I am quite new to modding, so it may be something simple I have missed - I have my fluids working fine in the world, but in BuildCraft tanks, they render as the missing texture, the purple and black squares - in the world, when they're placed in the world, they work fine. Also, when I apply things like luminosity, density etc. , they don't work at all. Here are the classes I have made, sorry if it is messy:

Any help would be appreciated - thanks in advance. Again, I may just be missing something stupid...

Also - these fluids render fine in the Tinkers Construct seared tanks and glass, just not BuildCraft tanks...

If this helps, I based my fluids code very much on Tinkers Construct's way of doing things - I found that, since that mod adds many liquids, that would be the best way to go.

Yeh, I second this OP - I'm having this weird problem too...
