Hello. I have some problem with WMO liquid. According to wowdev.wiki liquid in wmo group can be presented as xtiles*ytiles rectangle of liquid tiles with (xtiles+1)*(ytiles+1) heightmap.
In ADT we have "exists" bit map that tells us which tiles are not visible and we dont need to store data for every x*y tile. But in WMO we have data for all tiles even if they are not visible and I have no idea how to determine what tile is hidden.
For now i have only one option. Height level in non used tiles are 0.0 and I can discard them if they have zero level, but i think its not correct way.
Here is example map.jpg. Its undead cave in ThunderBluff.
Please tell me where im wrong. Thank you.
P.S. Sorry for my english.
