setAlpha and setVisible don't work (but setCollision yes) with filterTiles method

[captainHook]

Hi guys,

As mentionned on title, only setCollision work with the code beyond. Looking at the doc, I think el.setAlpha and setVisible() should work, am I missing something?

const erase =  MyStaticTilemapLayer.filterTiles(tile => tile.properties.erase)

erase.forEach(function(el) {

el.setVisible(false)

el.setAlpha(0.2)

el.setCollision(false)

})

}
