Embedded Files
My original intention was to make two rooms, one with the ghost, and one without the ghost where the player walks around. I would capture the ghost from the first room and project it onto a mirror in the second room to give the illusion that the ghost can only be seen in the mirror.
Ways I attempted this and why they didn't work:
1. Scene capture actors rendered to 2d textures
-Looked weird because the image moved with the character
-no reflections
2. Scene capture reflect actors
-had reflections but no way of rendering a remote texture
3. Scene capture portal actors
-worked perfectly except they made udk crash everytime I tried to play.
4. Decal on top of mirror
-didn't have the right aesthetic
5. Making the ghost appear only when the player is turned away from it
-This may have worked, but I couldn't figure it out. I could set the players rotation but it wouldn't affect the ghost mesh.
- I did notice that you can make a player rotate against its will by using set player rotation, which could be interesting for something else
I ended up placing a trigger close to the mirror (Scene capture reflect actor) that when touched makes the ghost appear and when untouched makes it hidden again. You can still turn around and see it but if you try to go near it it disappears.
Another mechanic I implemented was a flickering flash light that has to be turned back on whenever it goes out. This was much simpler and turned out well.
The Flashlight
The flashlight is just a spotlight attached to the player that is turned on by a trigger set to the E key that is also attached to the player. It stays on for 3 seconds during which the brightness is animated with a matinee sequence to get the flickering effect.
The Ghost
This is a simplified version of what I really wanted to do. Basically the ghost appears when you are standing in front of the mirror (Scene capture reflect actor) and disappears when you move from it. I also added a trigger that causes damage when you step where the ghost appeared.
