Screens & Surfaces
Experience Designer supports a wide range of projection surfaces — from simple flat screens to complex 3D geometry.
Built-in surface types
| Type | Description |
|---|---|
| Flat Screen | Standard rectangular projection surface |
| Cube | Box-shaped projection object |
| Room | Four walls and a floor with individually controlled surfaces |
| Cylinder | Full or partial curved screen; its properties can create one-shot top or bottom Circle screens |
| Circle | Circular or sector screen with direct domemaster UVs |
| Panadome Screen | Spherical section with separate left, right, top, and bottom angles |
| Dome Screen | Dome segment with adjustable radius and cap angle |
Adding a built-in surface
- Choose Add → Add Screen / Object.
- Choose a surface type.
- Set dimensions and parameters in the dialog.
- Position and rotate the surface using the 3D handles or properties panel.
Importing custom geometry
For unusual surfaces — curved façades, irregular shapes, or architect-supplied geometry:
- Choose Add → Add Screen / Object → Custom 3D Model.
- Select an FBX, OBJ, Collada / DAE, GLTF, or GLB file.
- The model is imported as a projection surface.
Imported models can be scaled, repositioned, and rotated like other objects. Use the 3D Model Helper in its properties to correct scale and alignment, work with individual mesh parts, or optimize the imported model. Maximum upload size depends on your account configuration.
Surface properties
| Property | Description |
|---|---|
| Width / Height | Dimensions in metres |
| Position (X, Y, Z) | World-space coordinates |
| Rotation (Pitch, Yaw, Roll) | Orientation in degrees |
| Gain | Screen gain value (reflectivity, where 1.0 = unity gain) |
| Receive Projection | Include or exclude the surface from projection and analysis |
| Projection Side | Receive projection from the front, back, or both sides |
| Base texture | Choose a material color, image/video, or Exaplay3 input for the surface |
Screen materials and media
In Screen Content → Base Texture, select the source you want to show on the surface:
- Material lets you choose a solid color with the color picker.
- Image / Video lets you upload or select an image or video.
- Exaplay3 uses a live Exaplay3 input when it is available for your plan.
This base texture helps the scene resemble the venue or planned content. Projected content and analysis are controlled separately.
3D Model Helper
Select an imported custom model, then choose Open 3D Model Helper in its properties. The helper opens a live preview with controls organized into four tabs:
- Align sets the model's source units, uniform scale, up axis, origin, and fine position offsets. Reference cubes and a human reference can help verify scale.
- Parts lists the model's mesh parts so you can show or hide individual parts. You can also trim the model: enable Trim model, then move or resize the red box in the preview. Use Reset crop to restore the full model.
- Texture checks UV coordinates and imported textures, provides test-pattern, checkerboard, and UV-grid previews, and can project UVs from the current view or restore the original UVs.
- Optimize reduces polygon detail to improve performance. Choose how much detail to retain, or restore the original detail.
Choose Apply to save the helper changes to the model. Reset restores the original imported model settings, while Cancel closes the helper without applying changes.
Working with multiple surfaces
Scenes can contain any number of surfaces. Analysis checks every visible screen that has Receive Projection enabled.
