Shader compilation on first load

On first launch, UE will compile the plugin's custom shaders. This may take 30–60 seconds. The editor will appear to hang briefly — this is normal.

Verifying the installation​

Open Edit → Project Settings → Plugins → Custom Tone Mappers.

You should see the plugin settings section with the Enabled toggle and the Tone Mapper dropdown.

Project Settings showing the Custom Tone Mappers section

If the section is missing, check the Output Log for errors from LogPluginManager or LogShaderCompilers.
