Apply Custom Shader Glitch Effects in OBS Studio

This guide explains how to apply a custom shader file to any video source in OBS Studio using a specialized plugin to create a real-time glitch effect. You will learn which plugin to install, where to find shader files, and the exact steps required to load and configure the shader to achieve a stylized, distorted aesthetic for your live streams or recordings.

Step 1: Install the OBS Shader Filter Plugin

OBS Studio does not support custom HLSL shaders by default. To enable this functionality, you must install a community plugin.

  1. Download the obs-shaderfilter plugin from the official OBS Resources forum or its GitHub repository.
  2. Close OBS Studio if it is currently running.
  3. Extract the downloaded zip file and copy the contents into your OBS Studio installation directory (typically C:\Program Files\obs-studio). This will merge the data and obs-plugins folders.
  4. Relaunch OBS Studio.

Step 2: Obtain a Glitch Shader File

Shaders in OBS use the HLSL (.effect or .shader) format.

  1. The obs-shaderfilter plugin comes pre-packaged with several example shaders, which often include a basic “glitch” or “analog distortion” shader.
  2. If you want a custom effect, you can find community-made shaders on the OBS forums, or write your own and save it as a text file with a .shader or .effect extension.

Step 3: Apply the Shader to your Source

Once the plugin is installed and your shader file is ready, you can apply it to any capture card, camera, media source, or window capture.

  1. In the Sources dock of OBS, right-click the source you want to apply the glitch effect to and select Filters.
  2. Click the + (plus) icon in the bottom-left corner of the Filters window under “Effect Filters.”
  3. Select User Effect (or Shader Filter, depending on the plugin version) from the list. Name the filter (e.g., “Glitch Effect”) and click OK.
  4. In the filter settings panel, check the box labeled Load shader from file.
  5. Click Browse next to the Shader file path field.
  6. Navigate to your shader file (if using the default plugin shaders, they are typically located in C:\Program Files\obs-studio\data\obs-plugins\obs-shaderfilter\examples). Select your chosen glitch shader file and click Open.

Step 4: Configure the Glitch Parameters

After loading the file, the shader will render on your source in the preview window. Most shaders expose custom parameters directly in the OBS interface.

  1. Adjust Variables: Look below the file path to find sliders for variables like distortion frequency, glitch intensity, scanline visibility, or speed.
  2. Fine-tune the Timing: If the glitch is too distracting, lower the frequency or speed settings to make the distortion occur less often.
  3. Toggle Visibility: You can quickly turn the glitch effect on or off during a stream by clicking the eye icon next to the filter name in the Filters list.
