Sorry about the cloud -- I intended it to be only for the "Morph" and "Morph alternate" animations. I used some software that I've been working on to import it into the model, and apparently it got some display information out of order. The cloud didn't appear in game but did appear in viewers I tested, but either way it should be fixed in the new version.
Speaking of which, I also did add the "Morph" animations in which he raises his sword, has some spinny white glows that only appear in game, and the Gargoyle's stone form spell effect art to make it look splashy. I also put a stone form sound effect in the model file for the morph animation.
Edit: In case you didn't want even as little as the red player-color hero-glow during the Stone Form, I've attached a second version where the glow shuts off in his alternate animation. However, the glow shutting off is not visible in viewer programs I tested, only in the actual Warcraft game editor.
