在此讲学，环境艺术家内特·斯蒂芬斯将展示如何建模和造型资产组装成的3D环境。参照摄影开始，内特锁定在对他的环境理念堵在他的Maya场景的布局和建设，将进一步完善和详细的ZBrush的参考对象之前。然后，他的各种资产导入到ZBrush的详细使用戈兹他Polygroups不同的部分，并限定了该模型的不同部分的折痕水平雕刻。
In this lecture, Environment Artist Nate Stephens will demonstrate how to model and sculpt assets to be assembled into a 3D environment. Starting with reference photography, Nate locks in on a concept for his environment before blocking in his scene layout in Maya and building reference objects that will be further refined and detailed in ZBrush. He then imports the various assets into ZBrush for detail sculpting using GoZ where he Polygroups the different pieces and defines the crease levels of the different parts of the model.

接下来，内特粗加工开始在ZBrush的使用Dynamesh他的造型。他开始在一些较大的功能细节雕刻加上更高频率的表面噪声网格之前。回到玛雅，他产生了一些细节片断为他的环境的低分辨率多边形模型以这些作品为ZBrush的产生在低分辨率的几何形状基础上增加一些高分辨率的细节之前。他补充更详细和完善，以使用多种工具，包括修剪动态笔刷的网格，由噪声掩蔽，然后，使用插入多网（IMM）的工具，他滴高分辨率网格到他的低分辨率工具，用简单的笔触，创造一个古老的石头砌块墙体的外观。
Next, Nate begins roughing in his sculpt using Dynamesh in ZBrush. He begins by sculpting in some of the larger feature details before adding the higher frequency surface noise to the meshes. Returning to Maya, he generates low-resolution polygonal models of some detail pieces for his environment before taking these pieces into ZBrush to generate some high resolution details on top of the low resolution geometry. He adds further detail and refinement to the meshes using a variety of tools including trim dynamic brushes, masking by noise and then, using the Insert Multi Mesh (IMM) tool, he drops high resolution meshes onto his low res tools with simple brush strokes, creating the look of an ancient stone block wall.

对于较小的，在他的一幕重复的特性，内特演示了如何在ZBrush的一个平铺的方式构建这些资产。最后，他移动到使用标准的造型和对称性工具复制这些特点在他的专栏，以测试规模，后来预习的功能进行进一步细化设计之前，在他的场景建筑特色的栏目。加入细的表面细节的特征和列作为一个整体之前，他然后添加更多的功能的列。一旦高分辨率刻画完成后，内特花时间做一些重新拓扑烘焙法线贴图，并使用x普通环境闭塞地图前。要完成的事情了，他用在狨Toolbag实时功能组装快速场景。这使他能够通过与狨猴的实时材料和基于图像的照明提取正常和环境光遮蔽贴图组装低分辨率资产全面可视化的资产。虽然本次讲座主要集中在雕刻环境细节的游戏艺术，它也是非常接近电影艺术家，观念艺术家，学生或任何人有兴趣学习如何生成可信的环境和建筑细节在3D环境中使用。
For smaller, repeating features in his scene, Nate demonstrates how to construct these assets in a tileable fashion in ZBrush. Finally, he moves onto designing architectural features to the columns in his scene using standard sculpt and symmetry tools before duplicating these features around his column to test for scale and prep the feature for further refinement later. He then adds more features to the columns before adding fine surface detail to the features and the columns as a whole. Once the hi-resolution sculpts are complete, Nate spends time doing some re-topology before baking normal maps and ambient occlusion maps using xNormal. To finish things off, he uses the real-time features in Marmoset Toolbag to assemble a quick scene. This enables him to fully visualize the assets by assembling the low resolution assets with the extracted normal and ambient occlusion maps with Marmoset’s real-time materials and image based lighting. Although this lecture is focused primarily on sculpting environment details for game art, it is also very accessible to film artists, concept artists, students or anyone interested in learning how to generate believable environment and architectural details for use in a 3D environment.
