From 42e1a127140965cac1be6e51e48192e341c2a29e Mon Sep 17 00:00:00 2001 From: Paramat Date: Wed, 27 Mar 2019 00:18:43 +0000 Subject: [PATCH] Require 'waving = 3' in a nodedef to apply the liquid waving shader (#8418) Makes the liquid waving shader per-nodedef like waving leaves/plants, instead of being applied to all liquids. Like the waving leaves/plants shaders, the liquid waving shader can also be applied to meshes and nodeboxes.
