## Cache

Using the parameters on this page you can calculate a cache for the movement of each point. On the one hand, this lets the animation play smoother, and on the other the cache is required when the scene is rendered with motion blur or via Team Render.

### Enable

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_ENABLE`

Use this option to define whether or not a calculated cache should be used.

### Compress

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_COMPRESSED`

Enable this option to compress the data saved in the cache (to save memory).

### Memory:

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_INFO2`

Displays the current memory usage of the cache.

### Calculate

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_CALCULATE`

Starts the cache calculation.

### Update

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_UPDATE`

Updates the calculation for the current frame.

### Empty Cache

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_DELETE`

Empties the cache.

### Load...

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_CACHE_LOAD`

A previously saved calculated cache can be loaded using this option.

### Save...

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_CACHE_SAVE`

A calculated cache can be saved for later use (compress the cache to minimize the saved cache file size).

### Auto Time

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_AUTOTIME`

If enabled, the entire Project length will be taken into consideration when calculating the cache.

### Start

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_START`

Enter the frame number at which the calculation of the cache should begin. This option will only be made available if **Automatic** has not been enabled.

### Stop

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_STOP`

Enter the frame number at which the calculation of the cache should end. This option will only be made available if **Automatic** has not been enabled.

### Offset

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_OFFSET`

This offset value will cause the points to be moved prior to or following a given cache calculation.

### Scale

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_TIMESCALE` · Range: [0..+∞%]

Use these values to scale the cache temporally to make the points move faster or slower than during recording.

### Cache

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_CACHE_LIMIT` · Range: [1..1000]

### Maximum Undo Limit (MB)

Parameter ID: `ID_CA_COLLISION_DEFORMER_OBJECT_CACHE_TEXT_LIMIT`

Use this setting to define the size of the cache made available for undos. If no limit is set, your computer's memory can be quickly brought to its knees.
