Editing

Use the Edit page to select, delete, clone, separate, recolor or crop data. Select the intended LiSplatActor before choosing a tool. Selected content is highlighted. Keep source files for important datasets.

Selection Tools

Rectangle and Polygon

Tool	Usage
Rectangle	Click two opposite corners to select the region. Backspace removes the last construction point
Polygon	Click to draw straight edges, or hold the left button and drag for a continuous outline. Double-click to finish; right-click to undo the last segment

Selection Management

Use Select All, Invert Selection and Clear Selection to manage the current selection. Inspect it from multiple directions before editing to avoid selecting unintended data behind the target.

Delete and Restore

Select content and use Delete. Use Undo to reverse an operation, or Redo to restore an undone operation. Check the active dataset and target before undoing.

Clone

1. Select the portion to copy.
2. Click Clone to create a copy while keeping the original content.
3. Select the generated object and move, rotate or scale it to fit the scene.
4. Check that the copy is complete, then save the edit and level.

Separate

1. Select the portion to handle independently and click Separate.
2. The selected content becomes a separate object and is removed from the original object.
3. Select the original and the separated object in the Outliner to inspect their boundaries, then adjust them independently.

Clone duplicates existing content. Separate splits part of a scene for independent handling. Check the selection first, especially around doors, windows and thin features.

Color Adjustment

Select the content, open Color Adjustment and observe changes as you edit. Start with small changes for large selections.

Parameter	Initial value	Usage
Brightness	0	Adjusts brightness of the selected data
Contrast	0	Adjusts light–dark differences; excessive contrast can lose shadow or highlight detail
Saturation	0	Adjusts color intensity
Opacity	1	Controls transparency of the selection
Temperature	0	Adjusts cool and warm color balance
Tint	0	Further adjusts color bias

These initial values preserve the original appearance. Confirm the selection before applying a local adjustment. Undo and retry if necessary.

Clipping

Crop Box

The crop box crops using an adjustable bounding box. Open the crop tool on the Edit page, translate, rotate and scale the box, then choose the retained side and boundary rule.

Figure: Crop box and cropping settings

Parameters

Parameter	Options and meaning
Crop Position	Razor gives a stricter boundary; Center suits general cropping; Edge retains more boundary detail
Keep Range	Inside keeps content inside the box; Outside keeps content outside
Transform	Adjusts box position, rotation and size
Execute Crop	Applies the current box and options

Steps

1. Select the LiSplatActor to crop and open the crop box tool.
2. Position and resize the box. Inspect upper, lower, front and rear boundaries from different angles.
3. Select Inside or Outside to specify which side to keep.
4. Start with Center for ordinary cropping. Compare Razor and Edge when a stricter or more inclusive boundary is needed.
5. Click Execute Crop. Undo, adjust and retry if the result is unsuitable.

Clipping Volumes

Clipping volumes control the displayed region using a box or sphere. Their position and size can be changed at any time.

Add and Assign

1. Select the LiSplatActor to clip. On the Edit page, click Add Clipping Volume.
2. The new LiSplatClippingVolume is assigned to the current LiSplatActor automatically, and the clipping effect appears.
3. Use the move, rotate and scale tools to position and size the clipping volume.

Clipping Volume Parameters

Parameter	Usage
Enabled	Applies clipping when selected; clear to disable it temporarily
Mode	Inside hides content inside the volume; Outside hides content outside it
Volume Type	Select Box or Sphere

To unlink a volume, remove it from the LiSplatActor's Clipping Volumes array. Delete unused volumes from the Outliner.

Section Planes

1. Select the LiSplatActor to section. On the Edit page, click Add Section Plane.
2. The new LiSplatSectionPlane is assigned to the current LiSplatActor automatically, and the section effect appears.
3. Move and rotate the plane through the target location.
4. In the plane's Details, select Enabled and switch Mode between Upside and Downside to choose the required section direction.

Clear Enabled to disable the effect temporarily. Remove the entry from the LiSplatActor's Section Planes array to unlink the plane.

Save and Save As

Save and Save As are both on the Edit page.

Action	Result
Save	Persists soft-deletion and color-adjustment edits in the current Gaussian asset
Save As	Exports the selected LiSplatActor as Gaussian PLY data, including crop, deletion, color-adjustment, clipping-volume and section-plane edits

Soft deletion hides the selected content without physically removing the original points. Use Save As to create a separate file containing the edited result.
