The 'water surface shader' was duplicated shader code in preparation for intended new water surface shaders. For development purposes the MTGame node 'default:water_source' had it's top tile assigned to 'water surface shader'. Due to shader duplication this commit does not cause any change to shader behaviour. --- .../water_surface_shader/opengl_vertex.glsl | 137 --------------------- 1 file changed, 137 deletions(-) delete mode 100644 client/shaders/water_surface_shader/opengl_vertex.glsl (limited to 'client/shaders/water_surface_shader/opengl_vertex.glsl') diff --git a/client/shaders/water_surface_shader/opengl_vertex.glsl b/client/shaders/water_surface_shader/opengl_vertex.glsl deleted file mode 100644 index 112db9bb5..000000000 --- a/client/shaders/water_surface_shader/opengl_vertex.glsl +++ /dev/null @@ -1,137 +0,0 @@ -uniform mat4 mWorldViewProj;
