Update 01.125: This week brings a new and updated character model into the game featuring an animated visor and PBR textures. This also brings more modding possibilities for your custom characters, so check out the helmet animation modding guide below. Other small features include pulsing highlights and new ambient sounds which create a better atmosphere in the game. Also, we fixed the freezing/crashing caused by mining on dedicated servers. Multiplayer optimizations continue with more blocks being rewritten in the new multiplayer code.
