Sometimes you feel finding Pokemon(s) in heavily forested area is impossible to do. Actually, Pixelmon mod provides Pokemon Sprites to be used to display Pokemons on minimaps graphically. Here is how to enable it.
Press "J" or any other bound key to open Journeymap in fullscreen.
Go to Settings.
Expand Minimap Preset 1. (this is the one we usually call as "Minimap")
Change Mob Display to "Large Icons".
Following these steps will allow you to fully see Pokemons that are around you including whether they are shiny or not!
Have fun and Catch them all!
