Are there any tutorials on this anywhere? sounds pretty smartRender a turn table so I can see the materials. Its the best way to check if they are too shiney or weird in some way. Then render a grey sphere and a chrome sphere. To check your environment and lighting. looks pretty cloudy which means there isnt much key lighting. might look better on a sunny evening.
To make it better I'd work on the materials and lighting. Try grading what you have but the shoulders stand out to me right now.
if its a MEL script you just go into your script editor and open it from thereI have a question, does anyone know how to open the plug-in's that are downloaded off of here in MAYA? I downloaded some and I can't find it to open.
