Instantiate an object inside the sphere

I am making a find hidden object game using a 360 photo and the camera is inside the sphere. It’s a VR 360 photo game, and I can point around using a laser pointer. I want to instantiate an object when the user press the trigger button and the laser is pointing to the correct answer. I manage to get object instantiate on the position by using Instantiate function, however the rotation of the object is just simply the rotation of the model I created. I want to make it looks like attach to the sphere, which mean the rotation of the object has to be changed. However I don’t know the math calculation to do it. Any advice or example will be highly appreciated. Thank you.

 

I would think LookAt would be easy enough. Make the target your camera.

if your object is still off say by 10 then rotate the prefab by 10 and that will line it up in game.

 

Hi Kobaltic1, thank you for your reply. I will try to use LookAt function!
