I've tried some tileset and tree swaps in cata just like I did in 3.3.5 and got this.
I mean blizzlike zones, not the noggit custom staff.
Tilesets work fine but trees are invisible now. But have their shadows.
Looks like I missed some blp for them or they can't be read by client.
Also client can't load the whole zone from account menu, it stops in infinite loading. Teleport from another map works fine.
I know that cata client files are read in other way than wotlk, but I don't fully understand how to work with them.
So if anyone helps me to fix this, I'll be grateful.
