I have multiple scenes, and for each scene, I set the camera differently. I’m using a single camera and adjusting its position through scripts, as I find manually configuring it in the Unity Inspector challenging. Instead, I run the project locally, position the camera as needed, and print its worldPosition and worldRotation values to use them for setting the camera.
The issue arises when I pan the camera, print the updated values, and use them to reposition the camera—it seems that the panned values are not being applied correctly.
The issue you’re experiencing with the camera position not updating correctly after panning may relate to how the camera’s target position and look-at position are set in your code.
In your setBaseCameraPosition function, ensure that both the camera’s target position and its position are being updated properly with respect to any transformations applied during panning.
Here is a recommended adjustment to check if the position values are being copied and set correctly:
setBaseCameraPosition(cam: Camera) {
if (!this.baseCamera) return;
const baseCamOrbitControl = GameObject.getComponent(this.baseCamera.gameObject, OrbitControls);
if (baseCamOrbitControl) {
// Get current camera position and orientation
const currentPosition = cam.worldPosition.clone();
const currentRotation = cam.worldRotation.clone();
// Set the target position based on the panned values
baseCamOrbitControl.setLookTargetPosition(this.goTarget, 1);
baseCamOrbitControl.setCameraTargetPosition(currentPosition, 1); // Ensure to use the updated position
}
}
Make sure that this.goTarget and other values are being set correctly before calling setBaseCameraPosition. The setCameraTargetPosition method allows you to specify whether the movement should be immediate or interpolated over a duration. Using a value of 1 will move it immediately to the target position.
If the problem persists, consider checking if any other scripts or components are affecting the camera’s position or if the correct values are being printed when you expect to set them.
You might want to confirm if the OrbitControls is properly enabled and whether there are other interfering systems affecting camera controls.
If you need further assistance, please provide more details about how and where the camera positioning happens, as well as relevant snippets of any related code.
Feel free to check the Needle Engine documentation for more insights on camera manipulation with the OrbitControls class: OrbitControls API.

As you can see in this video im panning before getting the positions and when i use these values in unity, its works except the panning part.

Regarding positioning the camera: you can move the scene camera in Unity and apply your scene camera position with the click of a button to your main camera too. No need to copy values:
What is goTarget? Is it assigned from Unity? If so then it’s missing a @serializable(Object3D) (same as componentObjects: GameObject[] at the top need a @serializable(Object3D)
I’ve attached a video to better illustrate the problem.
As shown in the video, when the OrbitControls script is turned off, the camera’s position and rotation are set correctly. However, when I enable orbitControls, it correctly applies the position but changes the rotation to an unintended value.
Looking for a solution to this ASAP.

Hello, as said in my reply here: OrbitControls is using a threejs object as a look target. When you use OrbitControls and you want to change the rotation of your camera you need to set the OrbitControls target position - otherwise it will be overriden the next frame again. This is how three.js OrbitControls fundamentally works and it is not a bug.
Just to clarify, if we are using OrbitControls, does that mean we cannot directly set the rotation by assigning (x, y, z, w) values like this? this.baseCamera.gameObject.setRotationFromQuaternion(quaternion);
Instead, do we need to set the rotation by using lookTarget and cameraTargetPosition like this?
You can also modify the position of the OrbitControls target directly if you prefer that.
So under the hood we use three’s OrbitControls (see target docs)
This is accessable via the Needle Engine OrbitControls component: needleOrbitControls.controls so to get access to the target of three.js you can use needleOrbitControls.controls.target and change it’s position(!) since it’s a Vector3.
I have multiple scenes: a source scene and several child scenes. Currently, I control the source scene’s camera using this approach, and I switch between scenes using the SceneSwitcher.switchScene method.
If my child scenes contain their own cameras, will those cameras be rendered when switching scenes?
If I want to reset the child scene’s camera (for example, I have a “Reset” button that, when clicked, should restore the camera’s position to its initial state after the user has zoomed or panned), what would be the best approach to achieve this?
If they have the MainCamera tag then yes. Otherwise not automatically. You can change the camera with this.context.setCurrentCamera(...) anytime
Add a component to your camera, this one saves in start() or awake() e.g. this.originalPosition = this.gameObject.worldPosition.clone() and (if using with orbitcontrols) orbitControls.controls.target.clone() in a variable.
Then add a reset() {...} method which you call from your Reset button onClick event and in that method you either call the OrbitControls methods OR directly set the gameObject’s worldPosition and worldQuaternion (this.gameObject.worldPosition = this.originalPosition;)
The issue I’m facing with moving the target is that the target is present in the source scene, and the child scenes have GameObject that depend on the target’s position. So, moving the target alone won’t work for me.
If I reload the scene, that should reset the camera, right?
I’m not sure I can follow unfortunately. Your child scene’s camera has an OrbitControls component - but you do want to reset this camera to your main scene’s camera position?
