Vanilla Spice Visuals

Changes from v1:

• fences have the same base model with three rungs instead of two, for consistency and versatility in builds
• fence gates now also share a base model with new textures for gate doors, though they all still swing open at one hinge; a few also have transparency now!
• iron bars are now a simple fence design rather than grates like the copper bars; can be used as both prison bars and fences
• item frames use a darker wood texture and a lighter background (compost bin for frame, sand for background, snow for glow background)
• retextured granite again, more redish like vanilla
• two new short grass variants, small flower patches
• tweaked iron blocks and items shading
• retextured leaf litter to be richer fall colors (previously unchanged)
• gave smoke particles an underside highlight
• tweaked chiseled resin brick from v1
• more bookshelf variants
• more mushroom variants and added shelf mushrooms to the model for the largest mushroom variant
• evened out density of color pigment for each stained glass color
• made clear, white, and grey stained glass a single pane with a dark leaded border (v1 had white borders and inner panes for white and clear)
