Field Cache Renderer
Updated: 3 Dec 2025
Playback a cached field simulation.
Field Cache Renderer
Method #
This node allows you to playback a cached field simulation. You can cache a field simulation by using a Field Cache node. This Field Cache node will output a ".field" file which can then be used as the "Field Cache" file in the Field Cache Renderer.
This node can still use field materials and has properties to tune the rendering and performance of the cached simulation.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X
The objects position along the local x-axis.
Position Y
The objects position along the local y-axis.
Position Z
The objects position along the local z-axis.
Rotation Heading
The objects rotation around the local y-axis.
Rotation Pitch
The objects rotation around the local x-axis.
Rotation Bank
The objects rotation around the local z-axis.
Scale X
The objects scale along the local x-axis.
Scale Y
The objects scale along the local y-axis.
Scale Z
The objects scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position
Toggle inheritance of the Position from the parent.
Rotation
Toggle inheritance of the Rotation from the parent.
Scale
Toggle inheritance of the Scale from the parent.
World Position Only
Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time
Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Field Cache
Field cache asset to use.
Visible
Control whether the node is visible or not to the scene.
Size
Set the size of the field cache playback.
Max Temperature (K)
The maximum temperature allowed in the field simulation
Ambient Temperature (K)
The base temperature of the field simulation.
Sharpen Amount
Set the amount of sharpening to perform on the cached field system.
Light Mode
Which mode of lighting to use.
Shadow Mode
Which method to use to calculate shadows.
Local Ambient Occlusion
Use local ambient occlusion.
AO Amount
Control the level of local ambient occlusion applied to the field system.
Filtering
Set the method of noise filtering.
- Full : Apply all noise filtering types.
- Temporal : Apply temporal noise filtering.
- Spatial : Apply spatial noise filtering.
- None : Don’t apply any noise filtering
These properties display live information about the fields system.
Parameter Details Cell Capacity Used
The percentage of voxel cells that are currently being actively calculated.
Memory Allocated For Simulation
The amount of memory allocated for the simulation.
Memory Required For Simulation
The amount of memory currently required for the simulation.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
