By default, every wall in the game throws sparks when a character takes hits against it, no matter what it’s made of: stone, marble, glass or wood. This mod removes those generic wall sparks, so sparks only appear where they "make sense": on metal surfaces.
Installation: Copy the three files (.pak, .ucas, .utoc) into TEKKEN 8/Polaris/Content/Paks/mods. Create the mods folder if it doesn’t exist.
