[Solved] Cliff Terrain Edition Problem

[Mechanic]

Hello. I am trying to edit the Outland cliff. After I edited some on Outland cliffs, and it's not showing the edited Outland cliffs in map after I edited them from GIMP. For grounds, they works fine in the map, but for cliffs, they are not showing. Was it the pathing texture name? Was it wrong type of cliff from choosing files? The way I edited the ground terrains, they works fine in the map, but for cliff terrains, it's not working. I am trying to edit the Outland 0-cliff terrain. Or, I have to use ReplaceableTextures\Cliff\Cliff0.blp? How do I convert DDS to BLP? Or, is there a cliff pathing for DDS? Like, "ReplaceableTextures\Cliff\Cliff0.dds"?

EDIT: Ah. I found it. It was replaceabletextures\cliff\cliff0_diffuse.dds
