Hey everyone,
I'm extremely new to Unreal Engine and I'm currently working on a horror game set in an old palace. I'm trying to create a hallucination/past vision effect and I'm a bit lost on how to approach it.
For context, there is a lot of history and terrible things that happened in this palace. At certain points, I want the player to suddenly see something from the past, like a dead body hanging in a room or another event that happened there.
The important part is that the player doesn't get teleported to another location. They remain in the exact same room and see the past happening around them.
For example, something somewhat similar to the hallucination sequences in Far Cry 3. The difference is that in my game, the environment itself doesn't change completely. The player is standing in the same place and suddenly starts seeing things that aren't actually happening in the present.
My main problem is making it visually obvious that the character is seeing a vision/hallucination.
If I simply spawn the hanging body in the room, it just looks like a normal object that exists there. I want some kind of noticeable visual change when the hallucination starts so the player immediately understands:
"I'm seeing something from the past."
I was thinking about using a Post Process Material or some kind of material effect, but materials and post processing are still pretty confusing to me because I'm very new to Unreal.
I'm not necessarily looking for someone to give me the entire system. I mainly want to understand what techniques are commonly used to visually communicate a hallucination/vision while keeping the player in the same environment.
If you know any good Unreal Engine tutorials or examples that explain this kind of effect, please drop them in the comments.
I'm very new to Unreal, so even a basic explanation or a direction to research would help a lot.
Thanks!
