Principles of Visual Effects

Visual effects (VFX) are used to create the illusion of reality in games. They can be used to create realistic environments, characters, and objects. They can also be used to create fantasy worlds and objects that would be impossible to create in real life.

In this article, we will be looking at the 5 principles of visual effects in games. These are the things that all game developers need to keep in mind when creating visual effects for their games.

Gameplay

This principle is key to VFX, so you need to grasp its implications. It concerns how well your VFX aids the gameplay. Even if a visual effect is awesome, it’ll amount to nothing if it pulls the player away from their goal or makes them lose.

Before you commence designing, evaluate what is essential to players and what they concentrate on while playing. Your VFX should supplement the gameplay instead of diverting attention from it. It should also provide information to the player without needing them to invest time in it.

A player’s actions should have a visual effect on the game world. This principle is often violated in poorly designed games, where the player’s actions have no effect on the game world whatsoever. This can lead to a feeling of disconnection and frustration on the part of the player.

A well-designed game will make sure that the player’s actions have a visual effect on the game world. This can be done through a variety of means, such as particle effects, lighting changes, or even simple changes in the color of the game world. By making the player’s actions have a visual effect on the game world, the player will feel more connected to the game and will be more likely to enjoy the experience.

Shape

There are many different types of visual effects that are used to create a unique and immersive experience for the player. One of the most important elements of these visual effects is the use of shape.

The VFX style can be easily determined by examining the shapes. They contribute to making the image more pleasing to the eye and reduce visual noise. A few tricks can be employed to style the shapes, like adding a blur to an effect, which creates an illusion of movement. 

You could try improving your painting skills while working on the shapes and texture. This usually helps create the most realistic and detailed effects.

 Different shapes can be used to create different visual effects in games. For example, round shapes are often used to create a sense of speed, while angular shapes are often used to create a sense of tension. By carefully choosing the right shapes for the right purposes, game developers can create a gaming experience that is truly one of a kind.

Value

It is essential to concentrate on adding contrast and light to your FX to generate a high-value series of effects. This will grab more attention to the focal point of your effect and form a distinct zone of concentration.

With a precisely defined focal point, the player will be fully aware of what they are looking at.The value principle is based on guidelines that determine the intensity of an effect. If a spell is more powerful, it has a wider value range and greater opacity than weaker spells. 

All energy values remain within limits so that effects blend into the environment and are visible. This keeps all spells evenly balanced and prevents any one spell from being more powerful than another.

Color

The use of color is one of the most important aspects of creating visual effects in video games. When used properly, color can create a wide range of effects, from setting the mood of a scene to conveying information about the game world.

There are a few basic principles that all game developers should keep in mind when using color in their games. First, colors should be used to create contrast and visual interest. Second, colors should be used to convey information about the game world. And finally, colors should be used to create a desired mood or atmosphere. When used correctly, color can be a powerful tool for creating visually interesting and immersive Effects.

The use of color in-game can be very helpful in terms of defining characters and their abilities. It can also be very intuitive and make the gaming experience easier. Red signifies an enemy and blue denotes an ally. Red is fire and blue is ice. It’s that simple. Colour can also intensify the effect or highlight the area of focus. This is one of the reasons it is deemed a pivotal Component of VFX.

Timing

The timing principle is one of the most important aspects of creating compelling visual effects in video games. This principle dictates that the effects must be in sync with the game’s audio and visual elements in order to create a cohesive and immersive experience for the player.

For example, when you are working on an explosion, you can start with a fast turn from a small ball of fire to the main explosion (anticipation) followed by a cloud of smoke that fades off with time (dissipation).

You can express it by lowering the value, saturation, and opacity. By altering color, value, opacity, and hue, you can create a realistic and well-timed visual effect.

Without proper timing, the video game effects can appear out of place and break the immersion of the game. This can be jarring for the player and take them out of the experience. 

Therefore, it is crucial that game developers and visual effects artists take the time to ensure that the timing of their effects is just right.By following the timing principle, Visual Effects artists can create stunning visual effects that will enhance the player’s experience and make the game more enjoyable.

Immersion

The easily forgotten principle of VFX is immersion. It defines how well an effect will stay consistent with the world and environment. In many cases, the sign that your VFX is well done is when a player isn't fully aware of its existence. When it blends so well with the environment and rules of the world it just feels natural. It's extremely important, as the moment a player realizes that something is off, they start looking for mistakes that will make their experience worse. To achieve a believable look of your effect you have to remember about couple of rules:

• Story: Make sure you can describe what your effect means in the game world. Is it a type of magic that evolved over the years? Does it have any connections to certain people/factions?
• Emotions: VFX can emphasize how the player feels in the world. Should they feel scared while entering a cave? Should they feel intimidated by the power of a certain spell? Or maybe they should feel safe when they are getting healed.
• Physics: Even if the world in the game isn't realistic, it should define some kind of physics, to make sure things are believable. What forces would work if a certain effect was taking place? How environment would react to that action?
• Transition: Our world is built in a way that everything has its transition. Smoke disappears slowly as it expands and blends with the air. Rain falls into the ground exploding into smaller droplets and soaking into the ground. Do you fade in/out all your elements accordingly? Do you make sure they blend well with all other elements and the environment (using depth/soft particles etc.)? If your effect would be a source of light, does your scene react to it?

Mastering immersion can take some time, especially while working on non-realistic games, but it's one of the most important principles to use if you want your effects to look flawless.
