|
|
|
Volume *Step* size is the distance between volume shader samples.
|
|
Cycles automatically estimates this distance based on voxel size in
|
|
volume objects and smoke simulations.
|
|
|
|
Render time can be reduced by increasing the step size, at the cost of
|
|
potentially losing some volume detail. For procedural volume shaders
|
|
that add detail, step size can be increased per object, material or world.

.. _bpy.types.CyclesRenderSettings.volume_step_rate:
|
|
|
|
Step Rate Render
|
|
Global multiplier on the step size for all volumes in renders.
|
|
Increase to reduce render time, at the cost of losing detail.
|
|
|
|
.. _bpy.types.CyclesRenderSettings.volume_preview_step_rate:
|
|
|
|
Viewport
|
|
Global multiplier on the step size for all volumes in the viewport.
|
|
Increase for more responsive viewport rendering.
|
|
|
|
.. _bpy.types.CyclesRenderSettings.volume_max_steps:
|
|
|
|
Max Steps
|
|
Maximum number of steps through the volume before giving up,
|
|
to protect from extremely long render times with big objects or small step sizes.
