I'm also having problems with BDcraft and TekkitLite. Some mods textures is default Minecraft and fire/water/lava is also default. And as far as i know I'm doing the right thing since most of the textures is working. I tried to add Steve's Cart textures that i found on BDcraft forum but it didn't work, the rails worked but it also worked before i patched but the carts, GUI and blocks don't. =/
Does anyone have a Pack that everything works and can upload it somewhere?
