Shifter

Shifter slides a single property up or down across a whole multi-selection at once, with a slider. It's the fastest way to nudge one value (brightness, a size, a speed) consistently across many effects.

Using it

1. Select the transformed effects you want to change (emitters, trails, and/or beams).
2. Open Tools → Shifter.
3. Pick the property and drag the slider. Every selected effect shifts together, live.

Because Shifter keys each object by kind, a mixed selection is handled correctly, each shifted through its own settings. It covers plain effects, 3D particles (including Lightning and Raycast Distance), transformed trails and beams, Screen Effects (shake, FOV, blur, ColorGrade, Bloom, impact frames, Distance) and Decals.

When to use it

• Making a group of effects a bit brighter or dimmer.
• Bumping a shared size or speed across a scene of effects.
• Any time you'd otherwise edit the same property on many objects one by one.
