Blur and Sharpen Filter - Shader Graph Basics

Uploaded June 2022 | Updated September 2026, 2 weeks ago

In this post-processing shader video for Unreal and Unity, I show how to create a filter that blurs the image by taking 7 samples and blending them together. Then I show how to use that same filter to apply sharpening to the final image. Next week, we'll use everything we've learned so far to create an underwater appearance.

Here's last week's video on creating fullscreen masks:
