Firstly, water seems to render opaque in the 3D skybox. how do I fix this?
Secondly, how do I modify how the player sees? like, add a black bar at the top of the screen etc.? I ask as I want to have an icon appear in the top-right of the screen when there's a puzzle nearby, and I need to render that over the user's view.
Thirdly, I am having an issue with func_doors. for some reason, when opening them, they open in both directions. how do I stop this?
I probably have more, but I can't think of them right now! thanks in advance for answers!
