Overview

This block does the same thing as double. It blends the motion supplied through other with the one from filtered, according to the parameters set in the properties.

The animation that is used in filtered only affects the bones specified in the properties.

Inputs

in

The finished blend goes here.


Outputs

otherSource of animations that will be processed first.
filteredThe source of animations to be added to other. This only affects the bones specified in the properties.


Properties

Blender
Synch Type

Motion Sync Type:

  • Keep phase – synchronizes motion lengths.
  • Keep speed – synchronizes motion speeds, irrespective of other parameters.
  • Match events – synchronizes using Blender/Events events, i.e. the corresponding events occur at the same frame in both motions but the time between the events is stretched as necessary.
  • Proportional_inv – blends motions inversely proportionally, that is, the first motion starts from the beginning while the second one starts from the end: new_time = target_total_time * (1.f - cur_progress).
EventsEvents for match events.
Add modeIf enabled, ADD MODE works according to the scheme. The delta multiplied by w1 is added to the data supplied via main. This works for cases where both main and add contain deltas.
Weight Mode

constant – w1 = 1.

param – w1 value is based on a corresponding parameter (additional fields appear in the properties, key0 = 0, key1 = 1).

replace – the weight returned by the blocks connected via add.

gesture – is calculated using the following formula.

if (looped)
	weight			= 1.f;
else if (progress <= 0.25f)
	weight			= (4.f * progress);
else if (0.25f < progress && progress <= 0.75f)
	weight			= 1.f;
else
	weight			= (-4.f * progress + 4.f);

Both looped and progress are extracted from add. Then the weight is interpolated with the previous value.

Filter
Filtered MattersUse filtered for request (normal and detached).
Locators Add ModeUse both filtered and other for locators.
Retarget for Parent SkeletonUse the full list of bones when calculating the parent skeleton's motions. Without this flag, re-target will use bind poses, likely resulting in lower quality.
BonesThe list of bones affected by the animation from filtered.
