Field Cache
Updated: 5 Sep 2025
Caches a Field system to disk for consistent results.
Field Cache
Method #
The Field cache node allows you to store the animation of a field to disk. This allows the animation to be scrubbed in time, and for simulations to run deterministically without the need to use effectors.
Cached fields may perform significantly better than running simulations live, as they are no longer being simulated and essentially just playback the sequence.
Field Baking Panel
The file extension for field caches is *.field.
After the baking is finished, any emitter and affector nodes may be disabled.
Field caching can generate very large files. The frame rate and field resolution will influence the size of the cached file.
Parameters
These properties control the core behaviours of the node.
Parameter Details Bake Now
Open baking window, with options for the file location and export range.
Field Cache
Cached File for playback. Once a file is selected, the rest of the field emission/motion will no longer function and this cached file will be played back instead.
Playback Rate
How quickly the cached field plays back.
Playback Time Offset
Offset the the start time for the cached field playback.
Looping
Allow the cached field to loop once the playback animation has ended.
Which channels to use in the field cache.
Parameter Details Temperature
Use temperature values in the cached field.
Fuel
Use fuel values in the cached field.
UV
Use UV values in the cached field.
Velocity
Use velocity values in the cached field.
These properties control the core behaviours of the node.
