Okay, time to see these materials for myself.
Plastic: Same as old one, just a bit smoother. Surfaces are still supported and have not changed, that is a good thing for me.
Wood and wood planks: WoodReviewer says it has improved, and it looks good. Cool.
Slate: Oh god what did they do to this?
Concrete: Seems too smooth. eh.
Metal: Why is this so bright and reflective. Oh yeah, metals are lustrous. Still weird.
Corroded metal: The corrosion looks like a texture from an old game, but still good.
Diamond plate: What the hell is this? This is DIAMOND PLATE. NOT PLASTIC PLATE. THIS LOOKS NOTHING LIKE A METAL MATERIAL. PLEASE CHANGE THIS DISGRACE OF A MATERIAL.
Foil: Too smooth.
Grass: Holy moly this is a downgrade. All creative uses of grass materials are ugly now.
Ice: Ice? More like snow.
Brick: Meh. It’s fine.
Sand: I don’t like it.
Fabric: I don’t like this either.
Granite: OH LORD WHAT DID THEY DO TO THIS WHY IS IT SO LIGHT? Goodbye Granite lava I guess.
Marble: Meh.
Pebble: Why is the pebble outline so think?
Cobblestone: Ew
Smooth Plastic: Nothing changed so it’s very good.
Neon: Nothing changed so it’s very good.
Glass: It’s good.
Forcefield: Nothing changed so it’s very good.
In conclusion, this update is a downgrade in many aspects.
