I have big problem with MR. I'm using maya 8.5. I don't have some really big scene, but when I try to render after a few seconds it say Mental Ray:Fatal error... save.... sistem may be unstable. In rows before it says that it can't render subD objects with creases. I actyaly modeled some walls just half of them because I don't need back walls, I tought that is a problem, then I selected all edges in all objects and did uncrease, but still doesn't work. what is funny, when I render only one model it works but all of them together it doesnt. Can anyone help?
