Unreal Engine – Sandbag Walls

所有网格都包括 LOD 和碰撞。对于大多数网格，LOD 0 介于 8k 和 13k 三角形之间。

纹理为 .tga 格式，分辨率为 4096×4096，附加细节纹理为 512×512 分辨率。环境光遮蔽和污垢蒙版放置在法线贴图蓝色和 Alpha 通道中，粗糙度纹理放置在反照率 Alpha 通道中，以减少着色器中的纹理提取。对于一些损坏的沙袋有一个额外的着色器和纹理，其中包含 alpha 以创建一些破坏轮廓的丢失线程。

由于着色器中使用的细节纹理，基础纹理可以轻松按比例缩小，而不会造成质量的重大损失，并且已经平衡以与 PBR 和逼真的光照配合良好

All meshes include LODs and collision. LOD 0 is between 8k and 13k triangles for most meshes.

The textures are in .tga format and 4096×4096 in resolution with additional detail textures of 512×512 resolution. Ambient occlusion and dirt masks are placed in the normal map blue and alpha channels and the roughness textures are placed in the albedo alpha channel to reduce texture fetches in the shader. There is an additional shader and texture for some of the damaged sandbags that has alpha in it to create some of the lose threads that break up the silhouette.

The base textures can be scaled down easily without major loss of quality due to the detail textures used in the shader and have been balanced to work well with PBR and realistic lightin
