@Stuart_McKay Hello! I know it's been a while, but there is a new Raycast Test behavior you can try out to detect objects at a specific angle. Hope this helps if you see this.
@Aidan_Fire thank you. I thought this may be the case. I think I can get away with adjusting the sprite before bringing it in.
This would have been a neat little thing to use to give the impression of depth if you could dynamically change the values depending on screen position. Maybe one for the future.
