Deletion Tool Explained
The Deletion Tool offers flexible options for safely removing actors, components, or instances within the editor. Use the modes below to tailor object removal to your workflow.
Component-Only Deletion
Purpose: Removes only the clicked component or instance instead of the entire actor.
Ideal For:
Deleting individual parts of multi-component actors
Fine-grained cleanup of instanced mesh elements
Key Settings:
Delete Only Target Component: Deletes the specific component or instance under the cursor.
Delete Actor if Last Component: When enabled, destroys the actor once its final static‑mesh component is removed.
Optional Settings:
Toggle the “Delete Actor if Last Component” option off if you prefer to manually remove empty actors.
Actor-Level Deletion
Purpose: Removes the entire actor with a single click.
Ideal For:
Quickly clearing out props, clutter, or temporary objects
Removing actors that don’t require partial component editing
Key Settings:
Disable Delete Only Target Component to delete the full actor.
Optional Settings:
You can keep Delete Only Target Component on temporarily and rerun the tool for individual parts if needed.
Decal Targeting
Purpose: Expands deletion to include decals and text components.
Ideal For:
Cleaning up surface markings like stains, stickers, or graffiti
Removing text render actors without affecting other components
Key Settings:
Target Decals: Allows decals to be detected and deleted.
Hover Decal Material: Custom highlight material used for decals prior to deletion (falls back to the default hover material if unset).
Optional Settings:
Modify the hover material to ensure decals stand out when previewing deletion targets.
Hover Highlight Preview
Purpose: Visually confirms which actor, component, or decal will be deleted.
Ideal For:
Preventing accidental deletions by showing a highlight before committing
Debugging selections when multiple objects overlap
Key Settings:
Hover Material: Material used to highlight hovered actors.
Hover Decal Material: Specialized highlight for decals; this needs to be a decal material.
Preview Scale: This is used on ISM/HISM instances to showcase which component is being targeted. Adjust this scale if the preview is not visible over the existing mesh.
Optional Settings:
Use distinct materials (e.g., bright colors) to differentiate between actor and decal targets.
Bounds Tuning
Purpose: Adjusts how the raycast selects decals and text components for more accurate targeting.
Ideal For:
Selecting thin or small decals that might be missed by default bounds
Ensuring consistent hit detection across varied component sizes
Key Settings:
Bounds Scale: Multiplier applied to decal and text bounds when ray testing.
Optional Settings:
Increase the value to make selection easier on small decals; decrease for higher precision in dense areas.
Each option is accessible in the tool’s settings panel, letting you adjust behavior, materials, and targeting preferences to fit different deletion scenarios.
