Unreal Engine 4 – Materials & Effects
For my technical specialization course I wanted to do some materials and particle work in Unreal Engine 4. One of the level designer in my group was going to do a puzzle game in Unreal Engine 4, and I thought it was a good opportunity to contribute to his project. As we were brainstorming together with an artist we came to the conclusion that a sci-fi setting was the best choice and used ‘Alien: Isolation’ for inspiration.
- Level Designer – Hector Hernqvist
- 3D Artist – Oscar Johansson
- Sound Designer – Simon Lindskog
My first task was to create an old looking monitor to be used in the puzzles and also by the main monitor that displays the player’s progression.
The Monitor material is made with five components:
- Vertical distort for making the image sway
- Distorted UVs (clamped V between 0.1-0.9)
- Flicker for giving it not so crisp look
- Random distort like an old VHS cassette
- Pixalated look
The puzzles were setup to render to a separate render target which was then used by the Monitor material.
To give the game some life I added smoke particle when the door were opening. The smoke particle was made with one emitter that was attached to the door and timed when exactly to go off.
Glow & Outline
I added glow and outline materials to give the player feedback for what items he or she could interact with. When the player is far away from the object it glows to give him or her that there is some object in the distance. When the player approaches the object it outlines so that the player knows it something it can interact with.
