AR Foundation in Unity: Getting Started

Improving Visuals With Post Processing

Although the AR doodling is ready, the visuals aren’t super appealing. To improve this, you’ll apply some post-processing effects:

• Vignette: This effect makes the edges on the screen darkened.
• Bloom: This effect makes doodle lines glow.

To set these up, do the following:

• Right-click an empty area in the Hierarchy and select Volume ▸ Global Volume, which handles the global post-processing effects.
• Select Global Volume and click New at Profile in the Inspector.
• Click Add Override in the Volume component and select Post Processing ▸ Bloom. Set the Boom’s Threshold value to 0.4, the Intensity to 2.5, and the Scatter to 0.7.
• Click Add Override again in the Volume component and select Post Processing ▸ Vignette this time. Set the Intensity value to 0.5, the Smoothness to 0.5, and other values as the default.
• Select AR Camera in AR Session Origin, and check Rendering ▸ Post Processing to enable in the Inspector.

Build and run.
