Getting Started with Captic

Captic lets you create interactive 3D spaces that run directly in the browser — no downloads required.
This guide walks you through creating your first space and adding a 3D model.

What you’ll need​

Before you begin, make sure you have the following:

  • A modern desktop browser (Chrome or Edge recommended)
  • A 3D model exported as .glb
  • Basic familiarity with 3D tools like Blender, Unity, or Unreal

No local installation is required.

1. Prepare your 3D model​

For best results and performance, prepare your model using these guidelines.

Supported format​

  • .glb (binary glTF)

Materials​

  • Use PBR / Principled BSDF materials
  • Supported maps:
    • Base Color
    • Normal Map
    • Optional Roughness / Metallic

Performance Recommendations​

  • Texture Resolution: 1024×1024 (recommended), 4K (maximum)
  • Max Textures per Model: 8
  • Total Triangles per Space: ≤ 200k
  • Lighting: Bake lighting and shadows into textures when possible.
tip

Optimizing assets is critical for mobile and VR performance.

2. Create a new space​

  1. Go to https://vrland.io
  2. Click Create your space.
  3. Choose Blank Space (or a template)
  4. Your space loads instantly in the browser

3. Open the editor​

Once inside your space:

  1. Click the Pen icon in the toolbar.
  2. The editor panel will appear.

4. Upload your 3D model​

  1. Click Upload
  2. Select your .glb file
  3. Spawn the model using Medium Quality
  4. Select the model in the scene

You can now move, rotate, and scale the model.

5. Physics and interaction​

With the model selected, you can enable:

  • Physics – enables collision
  • Initial physics – applies physics on load
  • Teleport – allows users to teleport onto the object
warning

If you enable physics and then scale the object, you must reload the space for the collision updates to take effect.

6. Debug and performance testing​

You can append debug parameters directly to your space URL.

Show FPS and draw calls:
?debugFps=true

Show physics debug information: ?debugPhysics=true

Force high material quality: ?materialQuality=H

Force medium material quality: ?materialQuality=M

Use these parameters during testing before sharing your space publicly.

7. Space capacity​

  • Default capacity: 30 users
  • Maximum supported capacity: 70 users
caution

Capacity should be adjusted before an event starts. Higher capacity increases performance and bandwidth requirements for all users.

Best practices​

  • Test your space on multiple devices
  • Keep geometry and textures lightweight
  • Avoid real-time lighting when possible
  • Reload after major changes (especially physics)

Next steps​

  • Add additional models and props
  • Optimize assets for events or large audiences
  • Share your space link with collaborators or visitors
