Overview
[b]Sand & Snow Coverage[/b] adds immersive snow and sand buildup on [b]walls[/b], [b]natural rock[/b], and a range of [b]patched mod objects[/b] (see Compatibility). It works much like RimWorld’s [i]vanilla snow-on-trees[/i] effect: nearby ground coverage is sampled so light dustings grow into thicker caps/edges, then recede with the weather.
This mod started as a side project for my other mod [url=https://steamcommunity.com/sharedfiles/filedetails/?id=3590124341] Advanced Bridges & Floors [/url] and works very well together with that.
Key Features
[b]- Natural buildup:[/b] Appears only where nearby ground actually has snow/sand for believable results indoors, outdoors, and courtyards.
[b]- Vanilla-like behavior:[/b] Mirrors the feel of the tree snow system (thresholds and gradual growth/melt).
[b]- Roof-aware visuals:[/b] [i]No[/i] buildup under roofs. If you build a roof later, any existing snow/sand overlay on that structure is cleared automatically.
[b]- Smart linking on walls:[/b] Seamless corners and fillers so long wall runs look continuous.
[b]- Gentle tint layer:[/b] Optional soft color wash to blend overlays with your textures.
[b]- Sand overlay (Odyssey required):[/b] Sand visuals only activate when Odyssey’s sand systems are present; otherwise sand is cleanly disabled (no errors).
Compatibility
Works out-of-the-box for many structures. Includes patches for:
• Advanced Bridges & Floors (platforms)
• Medieval Walls
• ReBuild: Doors and Corners
• Vanilla Furniture Expanded – Architect
• Hull Style: NANAME Walls
Load after those mods. Should be safe to add to existing saves.
Performance
Lightweight: cached lookups and safe refreshes that only redraw nearby cells when snow/sand depth changes. Sand hooks are gated when Odyssey is absent.
Compatibility
[b]Texture replacers:[/b] Mods that add or replace textures on objects can make snow/sand overlays fail to appear or look misaligned. For [b]walls[/b] and [b]natural rocks[/b], simple texture swaps usually work fine as long as the mod doesn’t change how the thing is defined (no custom shaders/graphics behavior).
[b]Adding support to new things:[/b] Create three small textures — [i]snow overlay[/i], [i]sand overlay[/i], and [i]tint[/i] — following the examples in this mod’s [i]Textures[/i] folder. Then add a tiny XML patch to the target [i]ThingDef[/i] to enable them. (Note: the sand overlay only activates if [i]Odyssey[/i] is installed.)
Updates
[b]27-01-2026[/b] – Did some code optimization to address performance slowdowns in some cases.
[b]21-01-2026[/b] – Update to make it compatible with [url=https://steamcommunity.com/sharedfiles/filedetails/?id=3543791340] Hull Style: NANAME Walls. [/url] Making diagonal sand and snow overlays.
[b]15-11-2025[/b] – Fixed a bug where snow/sand overlay did not always show right on multiplelayers of walls.
Added a mod option page, added in a default ON option that allow snow/sand overlay to spawn under 1 tile of roof.
The 1 tile under roof was done to make it show better on player build houes and more consistent spawn on rocks.
[b]04-11-2025[/b] – Did some optimazation so it even more light on performance.
[b]19-10-2025[/b] – First release.
