Edit Splat UI
Open Gizmo 1
This button opens the transformation gizmo, providing controls to move, rotate, and scale the selected 3D model. Detailed description can be found in section Gizmo.
Upload/ Replace 2Selecting this allows you to upload a new 3D Object file, which will overwrite the currently loaded model.
Delete 3Use this button to completely remove the selected 3D model from your current space.
Advanced Splat Editing Options
Rotation Speed
Rotates the asset around the Y axis. A positive value will rotate your asset clockwise. A negative value will rotate your asset counterclockwise.
Splat Brightness
Adjust the brightness of a splat. Use the input fields or drag the slider to the left or right to increase or decrease the value.
Splat Contrast
Adjust the contrast of your splat. Use the input fields or drag the slider to the left or right to increase or decrease the value.
Edit Splat (SuperSplat)
We offer our enhanced version of SuperSplat within Arrival.Spaces. This integration allows you to utilize all familiar SuperSplat operations. Furthermore, you can directly manipulate .spz files and save all changes by simply closing the SuperSplat window.
The following table provides an overview of the most commonly used operations in SuperSplat, their purpose, and typical use cases.
| Operation | Purpose | Typical Use Case |
|---|---|---|
| Crop / Trim | Removes unnecessary areas of a splat | Shorten loading times, focus on main object, remove empty or irrelevant regions |
| Merge / Combine | Combines multiple splats into one | Simplify render pipeline, boost performance with many small splats, scene optimization |
| Floater Cleaning | Removes floating/unconnected splats (noise, scan artifacts) | After importing scans, to reduce visual noise and optimize file size |
| Versions | Creates and manages different asset versions/checkpoints | Before major edits, to compare variations, or for collaborative workflows |
| Rearranging | Reorganizes splats or groups within a scene | Building structured scenes, correcting object placement, improving editing workflow |
| Insert Volume | Defines or places a volume (bounding box/shape) to isolate or constrain | Editing only part of a splat |
This option is only applicable to splat files (.SPZ, .PLY, .SPLAT, .SOG).
Collision
A collision is your way to make splats walkable. You can upload your own collision file or use our automatic generation tool.
Generate CollisionClick this button to automatically generate a collision mesh for your uploaded splat. After generating this icon will change to the icon.
Show Collision 4If a collision has been uploaded or generated, clicking this button will display the collision mesh as a purple overlay. In addition to that a gizmo menu opens, which is used to change the position of your collision.
Hide Collision 4If the collision is perfectly placed, you can deactivate the gizmo by using this icon.
Download Collision Pro5Clicking this button will download the current collision mesh. This allows you to refine the collision boundaries in an external program before re-uploading the modified file.
Delete Collision 6This will delete your collision.
After generating or uploading a collision, you can use this toggle to activate or deactivate your collision.
We have created a dedicated Space with video tutorials explaining how to upload splats, manipulate them using the Gizmo, and merge multiple splats while transferring them back to Arrival.Space.
