体积

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.
