I'm running into problems with one new model. Mostly the fact that the foot is moving parts of a thigh (Grouping and joints appear correct) and only on the Y and Z bends/rotations, not the X. Looking through to OBJ I found this entry: vn -1.#IND0000 -1.#IND0000 -1.#IND0000 vn -1.#IND0000 -1.#IND0000 -1.#IND0000 What do these lines do?
