“The Magnetic Field Update”
RCAPLUS V4 is now released.
This update adds the new
Magnetic Field feature.
It is designed to reduce the issue where controllers gradually drift away from their original positions due to random Force motion.
In previous versions, if random Force continued to be applied in certain directions, controllers could slowly move away from their initial positions over time.
V4 adds a soft return force that gently guides targets back around their captured
Home Position, while preserving the natural random motion that RCAPLUS is designed for.
New Features
1) Magnetic Field
A new
Magnetic Field feature has been added.
This feature records the current position of each selected target as its
Home Position, then gently pulls the target back when it moves too far away.
This is not a hard lock, and it does not directly correct the target’s position.
Targets still move freely with the existing random Force behavior, but when they drift beyond the configured range, an additional return Force is applied.
Main Controls
Use Magnetic Field
Turns the entire Magnetic Field feature ON / OFF.
When this is OFF, RCAPLUS uses only the existing Force / Torque / Morph behavior, and no Magnetic Field return force is applied.
Capture Home Position
Records the current target positions as their
Home Position.
Magnetic Field uses this position as the reference point, so press this button after placing the targets in the desired base position.
Affect Force Targets
Controls whether Magnetic Field affects normal Force targets.
When enabled, the normal controllers selected in RCA will receive return Force when they move too far away from their Home Position.
Affect Toe Targets
Controls whether Magnetic Field affects Toe targets.
When enabled, toe / small toe controllers can also receive return Force, making it easier to reduce drift around small foot controls.
Dead Radius
The free movement area around the Home Position.
Targets inside this radius will not receive return Force, allowing the random motion to remain natural and not feel overly constrained.
Field Radius
The outer range where Magnetic Field becomes fully effective.
After a target moves beyond the Dead Radius, the return force becomes stronger as it approaches the Field Radius, helping prevent continuous drifting.
Strength
Controls how strongly the target is pulled back toward the Home Position.
Higher values create a stronger return force, but if set too high, the motion may feel heavier or less natural.
Damping
Controls how much outward movement is reduced.
Instead of only pulling the target back, Damping also helps reduce the momentum of targets moving farther away from the Home Position, making overshooting and excessive oscillation easier to control.
Max Force
Limits the maximum return force applied by Magnetic Field.
Even if the target is far away or Strength is high, this value caps the force to help prevent unstable physics behavior.
The V4 Magnetic Field uses a
Home Position based system.
When you press
Capture Home Position, RCAPLUS records the current positions of the active Force / Toe targets.
After that, when a target moves away from its Home Position, an additional Force is applied to guide it back.
This helps reduce unwanted long-term drifting while preserving the random and organic motion.
Magnetic Visualization
A visualization feature has been added for Magnetic Field.
When
Show Magnetic Visualization is enabled, you can see the captured magnetic area directly in the scene.
The visualization includes:
- Home Position markers
- Dead Radius range
- Field Radius range
- Arrows showing the direction / strength of the magnetic return Force
This makes it easier to understand how Magnetic Field is affecting each target.
2) Toe Target Support
I added toe targets (left / right) to
Select Target.
These are special targets that normally do not function as standard Force Receivers, so they required a somewhat different implementation.
Because of this, their behavior is also slightly different from normal targets. Please keep the following points in mind:
- Do not set Torque values too high, especially on the X Axis
Toe targets can twist easily when Torque is applied. Much smaller values are recommended compared to other targets.
- It is recommended to set Foot control to OFF or Comply
Toe targets alone are mostly controlled by the Foot control, so they may barely move if the Foot control is too restrictive.
- For Magnet, enable “Affect Toe Targets”
Toe target support is implemented through a different route, so this option must be enabled for Magnetic Field to affect them.
🛠 Improvements
- Cleaned up unused functions and classes
Notes / Behavior
- Magnetic Field only works when Use Magnetic Field is ON
- Magnetic Field affects positional movement only; it does not add Magnetic Torque
- Magnetic Field is only an additional control layer for the existing cycle animation / Force animation. If you want to avoid overly large movement, it is recommended to first adjust the Force or Cycle values directly, then use Magnetic Field afterward
- If targets are changed, removed, or reloaded, it is recommended to capture the Home Position again
RCAPLUS V4 is designed to make long scenes easier to control, especially when using Force-based random motion on multiple controllers.
RCAPLUS will continue to improve.
