-state - 0 does 5 fades  
-state - 1 does 6 fades  
-native is missing third argument, also boolean, setting to 1 made vehicle fade in slower, probably "slow" as per NETWORK_FADE_OUT_ENTITY

+Fade the given entity back in, usually used after the entity has been faded out with [NETWORK_FADE_OUT_ENTITY](#_0xDE564951F95E09ED)
+
+When used on a entity which isn't invisible or faded out then the native will still work, it will just instanly make the ped invisible before fading in.
+
+Note that there is another boolean parameter which is missing, when set to true the fade in will be a little bit slower.
