 ## Shaders
 
-- [ksPerPixelMultiMap_emissive](https://gitlab.com/ac-custom-shaders-patch/public/acc-shaders/blob/master/docs/ksPerPixelMultiMap_emissive.md): alternative to “ksPerPixelMultiMap” with extra txEmissive map working as colored mask for emissiveness; 
-- [ksPerPixelMultiMap_NMDetail_emissive](https://gitlab.com/ac-custom-shaders-patch/public/acc-shaders/blob/master/docs/ksPerPixelMultiMap_NMDetail_emissive.md): alternative to “ksPerPixelMultiMap_NMDetail” with extra txEmissive map working as colored mask for emissiveness;
-- [ksMultilayer_fresnel_nm4](https://gitlab.com/ac-custom-shaders-patch/public/acc-shaders/blob/master/docs/ksMultilayer_fresnel_nm4.md)¹: alternative to “ksMultilayer_fresnel” with four normal maps aligned with detail maps instead of one texture mapped to main UV. Has four separate options for fixed tiling, instead of ksEmissive trick.
+- [ksPerPixelMultiMap_emissive](https://gitlab.com/ac-custom-shaders-patch/public/acc-shaders/blob/master/docs/ksPerPixelMultiMap_emissive.md): alternative to “ksPerPixelMultiMap” with extra txEmissive map working as colored mask for emissiveness.
+- [ksPerPixelMultiMap_NMDetail_emissive](https://gitlab.com/ac-custom-shaders-patch/public/acc-shaders/blob/master/docs/ksPerPixelMultiMap_NMDetail_emissive.md): alternative to “ksPerPixelMultiMap_NMDetail” with extra txEmissive map working as colored mask for emissiveness.
+- [ksMultilayer_fresnel_nm4](https://gitlab.com/ac-custom-shaders-patch/public/acc-shaders/blob/master/docs/ksMultilayer_fresnel_nm4.md): alternative to “ksMultilayer_fresnel” with four normal maps aligned with detail maps instead of one texture mapped to main UV. Has four separate options for fixed tiling, instead of ksEmissive trick.
+- stPerPixelMultiMap_specular: more advanced version of “ksPerPixelMultiMap” made by Stereo, with separate txSpecular texture for the color of specular, specular ambient, optionally colored reflections and better behaving txMaps allowing for wider variery of effects. Also, you can keep ambient occlusion in txMaps’ alpha channel instead.
+- stPerPixelMultiMap_specular_damage_dirt: same as previous shader, but with damages, for car paint.
