the release notes for 1.03 read that now sloped ladders are supported, but I couldn't find any information on how to set it up. If I tilt the ladder in the demo scene the camera goes crazy and starts to rotate around the character.
For the camera make sure you have set Update Character Rotation to false. This will then allow the camera to correctly follow the character. You will need to also replace the ladder animations with ones that match the slope that you are climbing. I will add this to the docs.
