I have a custom skeleton 3d Model I got from Unity, converted to dae, and imported to XCode.

In Unity, transform that lookAt, performs as expected. But in XCode, it is looking at reversed direction. It seems, that orientation and/or rotation of the SCNNode got reversed.

For example, in Swift

Test 1

1. Skeleton is at (0,0,0)
2. call lookAt (3, 0 , 0)

Result for Test 1 Skeleton is facing negative x direction. And back is facing positive direction (3).

Test 2

1. Skeleton is at (0,0,0)
2. call lookAt (3, 10, 0)

Result for Test 2 Skeleton is facing negative x direction Skeleton is facing negative y direction

Back is facing positive x direction (3). Back is facing positive y direction (10).

I dont know a lot about SceneKit and Unity. I used https://anyconv.com/fbx-to-dae-converter/ to convert my Unity FBX Asset to dae

Thanks in advance
