本视频教程是由Gnomon机构出品的MAYA与Mental ray制作照片级植物教程第一季，时长：9小时25分，教程使用软件：MAYA，Mental ray，大小：5.11 GB，格式：MP4视频，附工程源文件，作者：Alex Alvarez ，语言：英语。人人素材整理发布。
在本教学中,Alex将为大家讲解如何使用MAYA，Paint Effects还有mental ray来创建真实的植物。我们将先来学习基本的paint effect库，然后学习使用mia材质将笔触转换为可渲染的几何体。使用物理的太阳与天空，我们能够创建更多照片级真实的渲染结果。教学中详细讲解了如何详细的创建一个带有真实的有光泽的反射与透明效果的双面的shader。我们将通过diffuse,bump,reflection,还有translucency来为更多令人信服的shader映射参数。包括了如何组织UV进行拼贴得到各种不同的叶片纹理。我们将深入学习如何使用PAINT EFFECTS还有Ivy Generator tool工具来创建常青藤，还有如何将常青藤与植物分布到悬崖上的技术。所有相关的Paint Effects的设置都会被讲解到，这样我们就能创建自定义的植物库，最终我们就得到了一个照片级的森林小路。我们从零开始制作了各种蕨类植物，地面植被，吊兰等等，讲解了如何将它们继承到一个复杂的环境中。
The Gnomon Workshop Creating Plants in Maya and Mental Ray
Forest Techniques, part One with Alex Alvarez
In this DVD, Alex thoroughly covers how to create realistic plants using Maya, Paint Effects and Mental Ray. We begin by evaluating the default paint effects library and how to convert the strokes into renderable geometry with mia Materials. Using Physical Sun/Sky, we create more photorealistic renders through the creation of our own materials in a tonemapped workflow circumventing the default shaders created by Paint Effects. Everything necessary to create double sided shaders with realistic glossy reflections and translucency is demonstrated in detail. We look at mapping all relevant paramaters for more believable shaders via diffuse, bump, reflection and translucency, including how to organize UVs into tiles for variety in our leaf textures. We take an in-depth look at creating ivy with Paint Effects and the Ivy Generator tool and incorporate the renrensucai.com discussed techniques for plants and ivy into a cliff scene. All relevant Paint Effects settings are then discussed so that we can create our own custom plant library, all of which culminates in a photorealistic forest trail. We create a variety of plants from scratch including ferns, ground cover clover, spider plants and more, demonstrating how to incorporate them into a complex environment.
