CoreCG has unveiled MentalCore, its production-level rendering plugin for Maya. It is a plugin that provides an alternative to the standard rendering workflow for Maya and Mental Ray. MentalCore allows you to focus on creating great renders in less time, and the shader library provides a wide range of material, texture and utility shaders to help you achieve the look you need. Features include a completely new node-based render pass system, including a viewport preview option or exposure of a number of hidden mental ray features via Render Globals. This release contains a complete colour-management system and shader library and also a number of built-in camera features.
MentalCore is available from 189$ for node locked license, if you used introductory offer. For this you have to sign up by 15 January 2012 and purchase by 30 June 2012.
