本资料是关于参数化天空盒材质和行星着色器Unreal Engine游戏素材资源StarSphere，大小：90 MB，使用软件：Unreal Engine 4.12 – 4.27,语言：英语。
StarSphere 是一组资产，用于在 UE4 中创建美丽的太空天空盒背景。参数化材质让您可以控制构成星球的许多层，并让您的空间环境具有无限的变化。还提供了针对移动应用程序优化的材质和纹理以及三个额外的奖励功能：行星着色器、基于物理的 6 DoF 相机演员和太空尘埃效果蓝图。
特点：
静态 StarSphere 使用 8 个可调整层和 6 个贴花位置。您可以将球体平移锁定到角色并将球体旋转与定向光源对齐。
动态 StarSphere 在开始游戏时添加随机化。
行星着色器使用 2 个网格和材质实例来定义行星表面和大气。行星表面对表面、云层和夜光使用 3 个纹理级别。大气层伪造瑞利散射效应并提供日食效应。
6 DoF 相机actor 基于物理，提供最大线性/角速度和线性/角加速度的参数控制。
太空尘埃效果蓝图在玩家 pawn 的路径中重新定位发射器球体并生成太空尘埃粒子。可以控制更新速率、最小actor 速度和发射器位置偏移。
StarSphere is a collection of assets for creating beautiful space skybox backdrops within UE4. Parameterized materials let you control many layers that build up the star sphere and allow your space environment to have unlimited variations. Also provided are materials and textures optimized for mobile applications as well as three additional bonus features: planet shader, physics based 6 DoF camera actor and space dust effect blueprint.
Features:
Static StarSphere uses 8 adjustable layers with 6 decal positions. You can lock sphere translation to actor and align sphere rotation to directional light source.
Dynamic StarSphere adds randomize on begin play.
Planet shader uses 2 meshes and material instances to define planet surface and atmosphere. Planet surface uses 3 texture levels for surface, clouds and night lights. Atmosphere level fakes Rayleigh scattering effect and also provides eclipse effect.
6 DoF camera actor is physics based and provides parameter controls for maximum linear/angular velocity and linear/angular acceleration.
Space dust effect Blueprint repositions emitter sphere in the path of player pawn and spawns space dust particles. Update rate, minimum actor velocity and emitter position offset can be controlled.
