Unity Development — Post Processing Effects
Once you have Post Processing set up for your scene in your Unity project, it is time to start playing around. There are a lot of effects to choose from and it can be overwhelming. Why don’t we shed some light on a few of these.
The first simple effect we can look at is Bloom. Bloom basically takes all the whites and lighter part of your seen and adds a semi glow to them. You can change the intensity of that glow and even its color and threshhold.
Next we can look at a very strong effect called Color Grading. Just like it sounds, this allows you to change some of the colors of your scene. There are some helpful sliding bars that come with this effect. For instance, the Temperature attribute helps change the colors for your scene to either seem warmer or colder. Others include typical camera Hue, Saturation, Contrast.
Last, we’ll look at Grain. This one is fairly simple. Like old television static, the grain adds a grittiness to the visuals. This could be helpful for making a specific style in your game.
You can see the power of these post processing effects. These were just a sample of what you could use to make your scene look perfect. Don’t be afraid to play with the effects we covered and all the others. That is the best way to learn and get comfortable with them.
