How to Outline Any 3D Object in Unity 6

Описание: Make it clear which object your player is selecting! In this Unity 6.6 URP tutorial, we’ll create a selection outline using Shader Graph and a custom C# render pass.

You’ll learn how to render selected objects as a black-and-white mask, expand their silhouette by sampling neighboring pixels, and remove the original shape to leave an outline. We’ll also adjust its color and width and discuss the limitations of thicker outlines.

Project settings used: MSAA disabled and Render Scale set to 1.
