Merge all of an object’s cache clips

You can merge all your object’s cache clips at the same time by selecting the object, rather than its nCache clips, for the merge operation. On merge, all your object’s enabled cache clips are then baked to a single cache clip.

However, if any of your cache clips overlap, or if there are gaps between any of your clips, see Merge multiple non-overlapping nCache clips and Merge multiple overlapping nCache clips.

To merge all of an object’s cache clips

1. In the scene view, select the object whose cache clips you want to merge.
2. In the Trax Editor, select List > Load Selected Characters.

   All the current object’s caches appear as clips in the track view.

3. Make sure that all your object’s cache clips are enabled.
4. Depending on the object type, do one of the following:
   • For Nucleus objects, in the nDynamics menu set, select nCache > Merge Caches.
   • For fluid objects, in the Dynamics menu set, select Fluids nCache > Merge Caches.

   

   All your object’s enabled caches merge according to the current settings in the Merge nCache Options or Merge Fluid Cache Options window, creating a new nCache clip, cache file, and description file.

   The nCache clips you merged are disabled and their corresponding cache files on disk are not overridden or deleted.

To merge a single nCache clip

1. In the scene view, select the object whose cache clips you want to merge.

   You can merge individual scaled, cycled, or held nCache clips.

2. In the Trax Editor, select List > Load Selected Characters.

   All the current objects’s caches appear as clips in the track view.

3. Enable the nCache clip you want to merge and disable all other cache clips.
4. Depending on the object type, do one of the following:
   • For Nucleus objects, in the nDynamics menu set, select nCache > Merge Caches.
   • For fluid objects, in the Dynamics menu set, select Fluids nCache > Merge Caches.

   

   The single cache clip you selected merges according to the settings in the Merge nCaches Options or Merge Fluid Cache Options window, creating a new ncache clip, cache file, and description file.

   The nCache clip you merged is disabled and its associated cache file on disk is not overridden or deleted.

Merge multiple non-overlapping nCache clips

You can merge non-overlapping nCache clips.

However, if there are gaps between the non-overlapping nCache clips you want to merge, then the gaps are linearly interpolated and no cache data for those gaps is saved to the merged cache clip.

For example, you have three cache clips that you want to merge: cache clip 1 (frames 1-50), cache clip 2 (frames 50-100), and cache clip 3 (frames 150-200). When you merge these cache clips, the length of the resulting merged cache clip will be frames 1-200, but frames 101-149 will contain no cache data.

To merge multiple non-overlapping nCache clips

1. In the scene view, select the object whose cache clips you want to merge.
2. In the Trax Editor, select List > Load Selected Characters.

   All the current object’s caches appear as clips in the track view.

3. Enable the non-overlapping nCache clips you want to merge and disable all other cache clips.
4. Select the non-overlapping cache clips you want to merge.
5. In the Trax menu bar, select Edit > Merge Cache Clips.

   All selected non-overlapping nCaches merge according to the settings in the Merge Cache Clip Options window, creating a new nCache clip, cache file, and description file. See Merge Cache Clips.

   The nCache clips you merged are disabled and their associated cache files on disk are not overridden or deleted.

Merge multiple overlapping nCache clips

You can merge multiple overlapping nCache clips. The regions of the cache clips that overlap are blended according to their current Input Weight settings and any of their weight maps.

See Blend and set the weighting of nCaches from the Attribute Editor and Input Weights.

To merge multiple overlapping nCache clips

1. In the scene view, select the object whose cache clips you want to merge.
2. In the Trax Editor, select List > Load Selected Characters.

   All the current object’s caches appear as clips in the track view.

3. Enable the overlapping nCache clips you want to merge and disable all other cache clips.
4. Select the overlapping cache clips you want to merge.
5. In the Trax menu bar, select Edit > Merge Cache Clips.

   

   All the selected overlapping cache clips merge according to the settings in the Merge Cache Clip Options window, creating a new nCache clip, cache file, and description file. See Merge Cache Clips.

   The nCaches you merged are disabled and their associated cache files on disk are not overridden or deleted.
