环境光照，太阳，天气及其它室外环境

本篇给出了制作室外场景的链接（若需要在总体制图方面获取帮助，详见 Category:Level Design:zh-cn。）

文章

• 天空盒（2D） — 基础的天空
• 3D天空盒 — 在天空和中加入背景物体（例如建筑）
• 位移 — 地形（例如小山，悬崖，山洞或者不平坦的草地）
• 降水问题 — 确保你的雨/雪正常工作

实体

• light_environment:zh-cn - Both Direct and Diffuse light coming from the skybox:zh-cn ("toolsskybox" texture).
• env_sun:zh-cn - places a glow sprite in the skybox to represent the sun itself.
• shadow_control:zh-cn - necessary to control the dynamic shadows cast by light_environment.

 Note: light_environment:zh-cn, env_sun:zh-cn and shadow_control:zh-cn should be used together. Each entity represents only a one aspect of a naturally unified phenomenon; Sunlight. light_environment:zh-cn defines the direct sunlight settings and creates (buggy, unconfigurable) dynamic shadows which can only be overridden/controlled by shadow_control:zh-cn. env_sun:zh-cn places a glow sprite in the skybox where the sunlight comes from. To make sense of it all, just make sure that the <angles> (Pitch/Yaw/Roll) are set the same for all three entities. Unfortunately shadow_control:zh-cn does not have the Pitch override parameter, so its Pitch will be determined by the first of its <angles>. Even more unfortunately, the Pitch override rotation cannot be switched off and is measured counter-clockwise from the horizontal (so straight down is -90 degrees) whereas the <angles> Pitch is rotation is clockwise (so straight down is +90 degrees).

• func_precipitation:zh-cn - brush-based entity for rain or snow.
• func_viscluster:zh-cn - for merging visleaf:zh-cns in large, open areas.
• For nature props check the props_foliage folder in Hammer Model Browser.

材质

• Search for nature in the Hammer:zh-cn Material Browser.
• For smooth transitions between two types of material, such as grass to sand, use alpha blending with blend materials.
