adding and editing post effects

Post Effects can add some dramatic ambiance to an Amazon Sumerian. They add to scenes what common image filters add to a photograph. In this tutorial, we will look at each Post Effect, how they affect your scene, and how to use them.

You’ll learn about all post effects and their settings that are available in Amazon Sumerian.


Before you begin, you should have completed the following tasks and tutorials:

Step 1: Scene Setup

  1. From the Dashboard, create a new scene using the Default Lighting template.
  2. Title your scene “Post Effects”.
  3. Add some entities and objects to your scene. Note: The scene that appears in the screenshots throughout this tutorial is not available as a template. We used it to demonstrate how Post Effects affect a scene.
  4. Choose the top, or root-level entity in the Entities panel. For this exercise, we use the Post Effects scene entity.
  5. Navigate to the Inspector panel, and then open the Post Effects component.

    You can see that this scene already has two Post Effects: Bloom and Antialias.

Step 2: Testing Post Effects


The Bloom effect produces feathers of light that extend from the borders of bright areas within the scene. The effect is best described as a “glow”. Experiment with the Opacity, Size, Gain, and Intensity settings and values to best see how the Bloom affects your scene.


The Antialias helps to smooth out jagged artifacts on curved and diagonal edges of geometry. The visibility of this effect relies on the objects in your scene.

To add more effects to a scene, choose Add Effects at the bottom of the Post Effects component. We’ll work our way through the effects on the Add Post Effects menu, starting with Blur.

The best way to see the effects within the scene is to hide or delete all other Post Effects. Do this by clicking the visibility button (eye icon) or the close button (X).


The Blur effect adds a blurring filter to your camera. The Amount property controls how blurry the scene appears. The Size property controls the size of the individual blurred pixels. In most cases, a Size amount of 0.5-1.00 will produce the best results. To better understand the Blur effect, try experimenting with the property values. Be sure to hide or delete this effect before you continue.
