Whether or not use Mipmapping?

Ok, no time right now to discuss this, its a long story and need to share my way to speed up rendering time (without sacrifice production quality). Shortly, Mipmaps are designed for real-time rendering and has many critical weaknesses that made them useless in production, even the good performance is not guaranteed. So, if you use Mental Ray renderer anyway, may try mipmappimg. I found a good tutorial by Adnan Hussain on how to setup your Mental Ray to work with Mipmaps, which include as well, how to convert your bitmaps to Mipmaps. You can find also additional reference links about on Hussain web site.
