What you can build
Guide objects through transparent passages built from glass tube pieces or configurable procedural tubes.
The options below are grouped by the way you use them. Available controls depend on the selected object, editor mode and enabled features.
Creator guide
Options and behavior
Find the control you need, then follow the setup steps to test it in a level.
Glass tube pieces
| Option | What it does |
|---|---|
| Straight / Straight Big | Use a straight channel for short or long passages. |
| Quarter Circle / Half / Third | Use curved channel pieces. The curved pieces follow their visible wall shapes; the passage between the walls is a sensor rather than a solid block. |
| Wall collision | The inner and outer walls are solid. Match adjacent tube ends and keep the passage wide enough for the moving object. |
| Damage Skin | Supported glass tubes draw crack artwork over the glass when damage is enabled. |
Custom tube controls
| Option | What it does |
|---|---|
| Tube Radius X / Tube Radius Y | Set the horizontal and vertical radii of a curved custom tube. |
| Tube Angle / Tube Precision | Choose the curve extent and its geometric precision. |
| Tube Width / Tube Height | Set the dimensions of a supported custom tube shape. |
| Tube Thickness / Tube Wall Thickness | Tune the tube band and wall thickness. Check the resulting passage size in play mode. |
| Tube Alpha | Set tube transparency so objects inside remain visible. |
| Enable Tube Wall Texture / Wall Texture Type | Enable and choose a material for the walls. |
| Use Wall Bevel Texture / Wall Texture Compression / Wall Texture Scale | Tune the wall texture treatment and repeat scale. |
| Enable Tube Texture Fill / Tube Texture Type / Tube Texture Fill Scale | Enable and configure the fill treatment of the tube. |
Creator guide
Try it in a level
Start with a small scene so each setting has a visible result.
- Build a short channel from compatible pieces before making a full route.
- Align the open ends and test a ball that fits the passage.
- For a custom tube, tune dimensions, wall thickness and precision before decorating it.
- Test entrances, exits and joins at the expected speed, using Debug Draw to inspect collision if needed.

If the result looks wrong
Use the symptom to find the next setting to check.
The whole passage blocks motion
Confirm you used a tube object and that its wall settings leave enough room for the moving object.
