Ive been trying to find out alot of info on HDRI's as ive got a plane that ive modeled and what to have a realistic render of it. ive tried a HDRI a few times and it works great apart from the rather dodgy shadows it produces. Am i doing this wrong, or is it better to create a directional light aswell just for the shadows? as ive seen a couple of people doing it this way. im using maya 7 if that helps.
