MatID_Swap

This modifier let you change the current Material with a new MaterialID.
You can swap upto 10 sets of IDs at once.
the following image shows that the MaterialID on the teapot has been changed from..
1 -> 2
2 -> 3
3 -> 4
4 -> 1
If you set From to 0, the ID set would not be used.

MatIDSwap
This modifier also support the cache of updated MaterialID assignment.
If you turn on cache, this modifier will cache calculated MaterialID assignment once and reuse it until you force to update the cache.
Therefore, when you change the value, DO NOT turn on this option.
To refresh the cache, turn off cache and turn ON and OFF forceCacheUpdate.

 

MatID_Offset

This modifier let you offset MaterialID numbers.
If you had MaterialID 1, 2, 3, 7 and set Offset amount as 4, you will have 5, 6, 7, 11.

If you want to start MaterialID at a specific number, you can turn on Use Absolute StartID checkbox and set the Start ID spinner.

Download MCG: ExtractDeltas

This is a MCG modifier which extract the difference(deltas) between two meshes and let you apply the deltas to a different mesh.
You can use this modifier to make a corrective morph target. Check out this video for how to utilize this modifier.

This  modifier need two meshes to calculate deltas, “Original geometry” and “Corrective shape”.
This modifier will go through each vertex of two meshes and extract the difference(Corrective Shape- Original Geometry).
Then, the modifier will offset the vertex position with the calculated deltas.
Therefore, all three meshes must have the same number of vertex and topology.

You can also adjust the amount of deltas using Weigh value.
This modifier also has an option to cache the calculated deltas for better performance.

If you turn on cacheDelta, this modifier will cache calculated deltas once and reuse it until you force toupdate cache.
If your Original Geometry and Corrective Share is animated, DO NOT turn on this option.
To refresh the cache, turn off cacheDelta and turn ON and OFF forceCacheUpdate.
