So you put the correct path and a shadow, no a cube, is there? Then the skin probably is messed up, or the model is. Otherwise, if you're usig the WE preview, then it's probably still skins
shadows in the game and a cube (after eropenning of WE) is the 1 thing of skin path corruption.
try to reload you *.blp again(before delet it from imported files) i saw that sometimes importer at WE import files with 0 bytes... it also may be a problem...
Sometimes it does that, and then all my precious importing of 500 of KILLST4R's models' skins is wasted. It sometimes leaves them intact, or utterly corrupts them too.
