I am new to this game, and love it, im working on a map with rivers and lakes and stuff. but i diddnt know how to get my waterfall files on the game, so i youtubed it and followed directions. but it was a bad tutorial, and my files are ruined. i know how to make other objects, but the waterfall is vital. when i type in the files on the object maker, i get the waterfall mesh, but the material is just "BaseWhite" i tried tracing and undoing the steps i did on the tutorial, but its still not working. anyone know what to do?
