Hi, first- absolutely love the software. Puzzles are a total joy to work with!

I’m switching between cameras with a window.parent resize event listener that checks if the innerWidth is less than 768, which is working great. The problem comes when I try to do the same thing with this statement for initial load:
```
if (window.parent.innerWidth < 768) {
    app.camera = cameraMobile;
}
```
This does change the camera, but it is stretched vertically. Resizing the window at all fixes it- fitting the scene back into place how it should be, so I think it has something to do with how the scene size is recalculated when the v3d-container resizes. Any idea how I can fix this?

Both cameras are orthographic (blender); the initial camera is at 76.9 orthographic scale and the mobile camera is at 58 scale.

Hi,

you can try the following:

v3d.apps[0].onResize()

EDIT:

actually you should do it this way:
```
if (window.parent.innerWidth < 768) {
    app.setCamera(cameraMobile);
}
```
it does resizing automatically.

Hi Yuri. In which .js file should I add this code?

if (window.parent.innerWidth < 768) {
app.setCamera(cameraMobile);
}

Not exactly what you asked for but I find it works well to set the rendersize to something square in your 3D program, that way is your on a landscape screen it will extend the viewing area sideways, and if your in a portrait screen it will extend the field of view vertically.
