EEVEE 通过评估视锥体内的所有体积对象来模拟体积散射。

To achieve this, EEVEE uses several 3D textures which have a high video memory usage. The texture dimensions can be tweaked using the Resolution and Steps parameters.

分辨率: Controls the quality of the volumetric effects. Lower resolution increases video memory usage and quality.
步数 (阶梯): Number of steps to compute volumetric effects. Higher count increases video memory usage and quality. These samples are distributed along the view depth (view Z axis).
分布: Blend between linear and exponential sample distribution. Higher values put more samples near the camera.
最大深度: Maximum surface intersection count used by accurate volume intersection method. Will create artifacts if it is exceeded.

自定义范围#

When working with volume objects, EEVEE automatically computes the best depth range where to compute the volume sampling and lighting. In certain situations, this isn't enough and produces sub-optimal sampling which increases noise. This is particularly the case when using a volume shader inside the World or when working with large number of volume objects. The custom depth range can be enabled to restrict the computation of volumes to a certain range along the camera depth and thus increase precision.
