ArcCamera setting upVector crash

[DenysAshikhin]

Hi all,

I am trying to change the orientation of the arc camera rotation, which I know works on babylonJS sandbox, but when trying to implement it in react-babylonjs I get the following stack:

 math.vector.ts:2102 Uncaught TypeError: Cannot read properties of undefined (reading 'm')
    at Vector3.TransformCoordinatesFromFloatsToRef (math.vector.ts:2102:1)
    at Vector3.TransformCoordinatesToRef (math.vector.ts:2088:1)

Sample arcCamera:

 <arcRotateCamera
                  name="camera1"
                  target={
                    factoryDimensions.x !== 0
                      ? new Vector3(
                          factoryDimensions.width / 2,
                          -factoryDimensions.depth / 2,
                          factoryDimensions.height / 2  
                        )
                      : Vector3.Zero()
                  }
                  position={new Vector3(0, 0, 10)}
                  alpha={(6 * Math.PI) / 4}
                   beta={(7 * Math.PI) / 4}
                  upVector={new Vector3(0, 0, 1)} //ISSUE HERE
                  radius={
                    factoryDimensions.x !== 0 ? factoryDimensions.xMax : 75
                  }
                  upperRadiusLimit={
                    factoryDimensions.x !== 0 ? factoryDimensions.xMax * 2 : 75
                  }
                  lowerRadiusLimit={
                    factoryDimensions.x !== 0 ? factoryDimensions.xMax / 15 : 10
                  }
                  wheelDeltaPercentage={0.01}
                  wheelPrecision={2}

                  collisionRadius={new Vector3(0.1, 0.1, 0.1)}
                  upperAlphaLimit={3600 * Math.PI}
                  lowerAlphaLimit={-3600 * Math.PI}
                  upperBetaLimit={3600 * Math.PI}
                  lowerBetaLimit={-3600 * Math.PI}
        />

hi @DenysAshikhin I will deploy a fix for this once I get a chance to test. I think it's already on main branch for a month actually as it was an issue brought up in babylon.js forum...

[brianzinn]

@DenysAshikhin can you confirm it's fixed in 3.1.13?

[DenysAshikhin]

Yup it's fixed in 3.1.13
