Extra code control

Disable mouse scroll zoom

javascript code after camera creation

camera.lowerRadiusLimit = camera.upperRadiusLimit = camera.radius = 4.0;

Limite mouse scroll zoom

javascript

camera.lowerRadiusLimit = 1;
camera.upperRadiusLimit = 50;

Disable right mouse button drag pan

you can set a camera target
```
camera.setTarget(box, true, true);
```
you can also use make pan not working
```
camera.panningSensibility = 0;
```

invert camera drag rotation direction

javascript
```
camera.angularSensibility = -5000;
```

Force all material backface culling off

add that function for import mesh process

BABYLON.SceneLoader.ImportMesh("", "https://example.com/video/3d/", "my3d.babylon", scene, function (newMeshes) { for(let i = 0; i < newMeshes.length; i++){ newMeshes[i].material.backFaceCulling = false;} });

Problem: Blender Babylon export error after import FBX into blender:
- Solution:
  - go shading view, select each geometry to check its material network, delete those empty normal map node

Problem: my model in babylon view looks like backface culling, not display some face
- Solution:
  - go 3d software, check if all the face normal facing outside. check normal direction of those poly face. with face display and show normal to check.

Problem: chrome, safari shows focus indicator (aka a border line) when mouse select it

Solution: css

canvas {
  outline: none;
  -webkit-tap-highlight-color: rgba(255, 255, 255, 0); /* mobile webkit */
}
