# Adding WorldLabs Environment to Unity Scene **Date**: 2025-12-02 **Status**: Assets imported ✅ | Need to add to scene ⏳ ## Quick Steps ### Step 1: Add Collider GLB (Required for Navigation) 1. **In Unity Project Window**: - Navigate to `Assets/WorldLabs/` - Find `Modern Tropical Luxury Residence_collider.glb` (or similar name) - **Drag it** from Project window to **Scene Hierarchy** (left panel) 2. **Position the Collider**: - Select the GameObject in Hierarchy - In Inspector, set Transform: - **Position**: `(0, 0, 0)` - **Rotation**: `(0, 0, 0)` - **Scale**: `(1, 1, 1)` 3. **Verify it's in Scene**: - You should see the living room geometry in Scene view - If not visible, check: - Camera position (might be looking at wrong angle) - Scale (might be too small/large) - Mesh Renderer component is enabled ### Step 2: Add PLY Splats (Optional, for Visuals) **Note**: PLY splats require Gaussian Splatting plugin (already installed). 1. **In Unity Project Window**: - Navigate to `Assets/WorldLabs/` - Find the PLY files (e.g., `cafcb2c0-c073-435e-adc5-406e6588e0db_ceramic_500k.ply`) - **Drag them** to Scene Hierarchy 2. **Position Splats**: - Set Transform Position to `(0, 0, 0)` (same as collider) - They should align with the collider geometry 3. **If Splats Don't Render**: - Check if Gaussian Splatting plugin is installed (Window > Package Manager) - PLY files may need specific material/shader - Check Unity Console for import errors ### Step 3: Verify in Scene View 1. **Open Scene View**: - Click on "Scene" tab (next to "Game" tab at top) - Or: Window > General > Scene 2. **Frame the View**: - Select the collider GameObject in Hierarchy - Press `F` key (frames selected object) - Or: Right-click in Scene view > Frame Selected 3. **Check Camera**: - Select Main Camera in Hierarchy - In Scene view, you should see the camera preview - Adjust camera position if needed: - Position: `(0, 5, -10)` (looking at origin) - Rotation: `(15, 0, 0)` (slight downward angle) ### Step 4: Add Lighting (If Needed) 1. **Check for Lights**: - Look in Hierarchy for "Directional Light" - If missing: GameObject > Light > Directional Light 2. **Adjust Light**: - Position: `(0, 10, 0)` - Rotation: `(50, -30, 0)` (angled down toward scene) - Intensity: `1.0` (adjust as needed) ## Troubleshooting ### Nothing Visible in Scene - **Check Scale**: Collider might be tiny or huge - Try setting Scale to `(10, 10, 10)` or `(0.1, 0.1, 0.1)` - **Check Position**: Object might be far from camera - Reset Position to `(0, 0, 0)` - **Check Mesh Renderer**: Ensure component is enabled - Select GameObject > Inspector > Mesh Renderer > Checkbox enabled - **Check Camera**: Camera might be looking wrong direction - Select Main Camera > Inspector > Transform - Set Position: `(0, 5, -10)`, Rotation: `(0, 0, 0)` ### Collider Not Showing - **Check Import Settings**: - Select GLB file in Project window - Inspector > Model tab > Scale Factor: `1` - Inspector > Materials tab > Material Creation Mode: Standard - **Check Mesh**: - Select GameObject in Hierarchy - Inspector > Mesh Filter > Mesh should be assigned - Inspector > Mesh Renderer > Material should be assigned ### PLY Splats Not Rendering - **Check Plugin**: - Window > Package Manager - Look for "Gaussian Splatting" package - Should show as installed - **Check Import**: - PLY files may still be importing (check progress bar) - Check Unity Console for errors - **Check Material**: - PLY splats may need specific shader - Check GameObject > Inspector > Material settings ### Scene View is Empty - **Check Scene Tab**: Make sure you're in Scene view, not Game view - **Frame All**: Right-click in Scene view > Frame All - **Reset View**: Scene view toolbar > Click "2D" to toggle, then back to 3D - **Check Layers**: Scene view toolbar > Layers dropdown > Ensure "Default" is checked ## Quick Reference **Unity Project**: `C:\Users\sandr\My project` **Assets Location**: `Assets/WorldLabs/` **Collider GLB**: `Modern Tropical Luxury Residence_collider.glb` **PLY Splats**: Files with `.ply` extension in `Assets/WorldLabs/` **Transform Settings**: - Position: `(0, 0, 0)` - Rotation: `(0, 0, 0)` - Scale: `(1, 1, 1)` (adjust if needed) **Camera Settings** (if needed): - Position: `(0, 5, -10)` - Rotation: `(15, 0, 0)` --- **Austrian Precision**: Drag from Project to Hierarchy, set Transform, frame view with F key! 🇦🇹🏠
