Hi all,

I can not find the rule to convert the rotation from unity to unreal.

In unreal, I use GetActorQuat() to get the actor rotation.

I have uesd from Unity3D[x,y,z,w] to UE is [y,z,x,w].

But the rotation value in unreal is usually multiplied by a minus sign with unity.

And there are no rules in any rotation.

EX:

unity: Set Rotation Z->170

data.rotation.x: 0.000000

data.rotation.y: 0.000000

data.rotation.z: 0.996195

data.rotation.w: 0.087156

unreal: Set Rotation X->170

data.rotation.x: -0.000000

data.rotation.y: 0.000000

data.rotation.z: -0.996195

data.rotation.w: 0.087156

unity: Set Rotation Y->80

data.rotation.x: 0.000000

data.rotation.y: 0.642788

data.rotation.z: 0.000000

data.rotation.w: 0.766044

unreal: Set Rotation Z->80

data.rotation.x: -0.000000

data.rotation.y: 0.642788

data.rotation.z: 0.000000

data.rotation.w: 0.766044
