Hello , im currently trying to develop an arcvhiz real time walkthrough project for people to navigate through. What i found was that people that do not play games have a very hard time to move in the environment using the wasd or arrow keys. For this reason i try to make the movement controls more user friendly by simpling clicking and moving to the desired location. The problem now is that my player actor can pass through certain narrow passages using conventional controls, but when i use the simple move to location command found in blueprints those passages are considered too narrow for the player to pass through. I will provide you with pictures to further understand the problem i encounter even better.
You may have more luck asking this in the blueprint scripting forum. I think you can tweak the nav mesh to have less of a gap to the side. You can also make you player character “thinner”. The default is pretty large.
