How Disable Player Shadows & Post-Processing Effects works in ClientAppSettings.json
Turns off dynamic character shadows and bloom/depth-of-field blur to boost visibility and 1% low frame times.
When you adjust **Engine Settings & FastFlag Editor** inside Bloxstrap, the bootstrapper writes `FIntRenderShadowIntensity / FFlagDisablePostFx` into `ClientSettings\ClientAppSettings.json` before `RobloxPlayerBeta.exe` initializes its renderer.
Recommended values and stability tips
- **Accepted values:** `ShadowIntensity = 0, DisablePostFx = True`. Stick to the built-in GUI preset under Engine Settings unless you are testing a specific JSON override.
- **Resetting:** If a custom value causes visual artifacts or a startup crash, use Reset FastFlags to default.
- **Installer:** Download the latest Windows build of Bloxstrap from /download.
