imported OBJ´s shader turns black
I imported a OBJ file done done in 3dsMAX into maya. everything is fine. arranged it and performed freeze transform - suddenly the shader turns black.
assigned a new shader - nothing. another geometry in this scene is shaded correctly in the viewport. the imported one has no odd connections in the hypergraph. looks just any "normal" object. no matter what I do, viewport doesn´t shade the object correctly anymore..
what has happened?
everything starts and ends in the right place at the right time.
