− | ==Inside Points==
| + | |
− | An inside point allows the mapper to make a mesh solid. This means that regardless of what the player tries to do, they will not be able to go through the object, or end up spawning inside a mesh unintentionally. When you drive through a box, especially with the Oscillation Overthruster flag, you will be inside of a building and sealed to it. Without inside points, especially to larger meshes, you will just end up on the inside of it and be able to shoot and drive normally. This is sometimes intentional, but usually not wanted. Inside points remedy this.
| + | |
− | | + | |
− | In order to have successful inside point coverage, you need to make sure all faces of your mesh are in "line of sight" to the point you specify. This means that all faces have direct vision to that point, just as if that point was a point of light and all the faces were eyes. Only what can be seen through a straight line will be considered the inside for that face.
