Volumes¶
Reference
- Panel:
EEVEE simulates volumetric scattering by evaluating all volume objects inside the view frustum.
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.
- Resolution
Controls the quality of the volumetric effects. Lower resolution increases video memory usage and quality.
- Steps
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).
- Distribution
Blend between linear and exponential sample distribution. Higher values put more samples near the camera.
- Max Depth
Maximum surface intersection count used by accurate volume intersection method. Will create artifacts if it is exceeded.
Custom Range¶
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.
- Start
Start distance of the volumetric effect.
- End
End distance of the volumetric effect.
