Generates an additive output pose by calculating the difference between the two input poses(additive pose - base pose). These input poses do not need to be additives themselves.

By default, the output pose is local space additive, but the node is able to generate a mesh space additive instead if specified in the details.

The output pose can then be applied as an additive down the line, for example using the Apply Additive or Apply MeshSpace Additive nodes.

Applying the Output to the “Base” input pose will yield the input of the “Additive” input.

Note about a warning Pre-UE5.3

Before Unreal 5.3 there was a bug that would expect the “Additive” input to already be an additive animation to begin with and would throw a warning if it was not.

This warning was just a bug though and, as far as I can tell, did not have any impact on the functionality of the node.
