本视频教程是由Gnomon机构出品的森林制作技术3-Maya与PAINT EFFECTS中树木制作教程,时长:7小时14分,大小:3.76 GB,格式:MOV视频,教程使用软件:Maya AE,作者:Alex Alvarez,语言:英语。。

在本教学中,Alex为我们讲解了如何在使用Paint Effects引擎来创建真实的树木。我们首先会查看默认的PFX library,它已经为了mental ray的工作流程被转换为了POLYGON。接着ALEX我们讲解了如何自定一个树木,使用一个预置作为起点。所有相关的paint effects属性都被讲解到了,这样我们就明白了如何得到所希望的枝干,叶子,运动效果的树木。接着我们在PHOTOSHOP中创建贴图,并且设置MIA材质,接下来探索了如何使用物理真实的sun/sky,还有摄影曝光度的知识。还准备了在风力影响下的树木运动,包括使用用户自定义的预设置来创建一个随机的资源库,将它们用于一个高POLY数的公园场景。其中讲解了在公园中布满树木,植物,草,落叶的技术,使用的方法包括了表面发射,实例化,粒子表达式等。Alex渲染出了这个动态的场景。包括了ZDEPTH流程呢个,在AE中使用Lenscare, Magic Bullet,还有Sapphire插件合成最终结果。他还为大家分享了使用体元来创建体积雾效,渲染为一个单独的层,生成最终的4K大小公园合成效果的技术。最后还介绍了很多创建自定义植物的技巧,从而让你的默认资源库更加的有用,可用于专业的项目中,例如大叶植物,棕榈树,松鼠,柳树,竹子。

Maya 是目前世界上最为优秀的三维动画的制作软件之一,主要是为了影视应用而研发的,所以在出世后不久就在《精灵鼠小弟》、《恐龙》等这些大片中一展身手。除了影视方面的应用外Maya在三维动画制作,影视广告设计,多媒体制作甚至游戏制作领域都有很出色的表现。初识Maya 是目前世界上最为优秀的三维动画的制作软件之一,它是Alias|Wavefront公司在论坛1998年才推出的三维制作软件。虽然相对于其他老牌三维制作软件来说Maya还是一个新生儿,但Maya凭借其强大的功能,友好的用户界面和丰富的视觉效果,一经推出就引起了动画和影视界的广泛关注,成为顶级的三维动画制作软件。

The Gnomon Workshop Creating Trees in Maya Paint Effects Forest Techniques, Part Three

Forest Techniques, part Three with Alex Alvarez

In this DVD, Alex demonstrates how to use the Paint Effects engine in Maya to create realistic trees. We begin by looking at the default PFX library, which has been converted to polygons for a Mental Ray workflow in an interactive instancer driven scene. Alex then thoroughly demonstrates how to customize a tree, using a library preset as a start point. All relevant paint effects attributes as discussed so that it becomes clear how to create trees that match the desired look for branching, leaves and behavior. Creating custom textures in Photoshop and setting up miaMaterials is then explored using Physical Sun/Sky and photographic camera exposure. Tree animation with wind turbulence, including how to create a randomized library from a user-defined preset, is generated in preparation for incorporating trees into a high-poly park scene. Techniques for populating the park with trees, as well as plants, grass and ground leaves, are discussed in a dynamic and flexible workflow via surface emission, instancing and particle expressions. Alex renders the animated scene, including his ZDepth bbs.renrencg.cn workflow, compositing the final result in After Effects using the Lenscare, Magic Bullet and Sapphire plug-ins. He also shares his techniques for using volume primitives to create volumetric fog effects, rendered as a separate pass, creating a final 4k comp of the park scene. In conclusion, a variety of tips for creating custom trees are shared in order to make the default library a more useful start point for professional projects including broadleaf, palm, pine, willow and bamboo.
