+
+## OBS XBRz-like shader fIlter
+
+1. get a copy of [obs-shaderfilter](https://github.com/exeldro/obs-shaderfilter/releases) plugin and install it
+2. place [files from this repo](./shaders) anywhere on your device
+3. add a userdefined shader to your source's filter list
+4. select the \*.effect file in the "load from file"
+5. toy with the settings!
+
