A deterministic setup standard for Unity 6 2.5D isometric tilemap projects. It locks down the diamond 2:1 grid projection, Pixels Per Unit (PPU) standard, orthographic Pixel Perfect Camera, and sorting-layer hierarchy so the classic isometric failures: jittery sprites, wrong z-order, blurry pixel art, misaligned tiles, never appear in the first place.

Change PPU after Sprint 1 and you buy a 10 to 30 minute full reimport. That is why this project seed locks every isometric invariant behind constants and editor validators:
- Creates the GameConstants.cs single source of truth before anything else: PPU (64 mobile-friendly or 128 high-res, locked after Sprint 1 because changing it forces a 10 to 30 minute full reimport), grid cell size (1, 0.5, 1), tile anchor (0.5, 0.25, 0), sprite pivot (0.5, 0) and the reference resolution 480x270. Literal values anywhere else in the codebase are banned and grep-checked.
- Configures the Grid for the 2:1 diamond projection: Cell Layout Isometric, Cell Swizzle XYZ, Cell Size (1, 0.5, 1). A GridInvariantValidator hooks into scene saving and hard-blocks the save if any Grid or Tilemap in the scene violates these values.
- Sets up the camera as orthographic plus Pixel Perfect Camera: orthographic size computed from reference resolution and PPU, upscale render texture on, pixel snapping on. Without this, sub-pixel jitter makes characters shimmer and players quit within seconds.
- Locks the sorting layer hierarchy to exactly Default, Ground, GroundDecal, Entities, AirOverlay, FX, UI in that order. A SortingLayerValidator runs at editor load and logs errors on any count or order mismatch; per-scene layer creation is forbidden.
- Installs the SpritePPUEnforcer AssetPostprocessor: every texture under Assets/Sprites gets PPU from GameConstants, Point filtering, bottom-center pivot and mipmaps off at import time. A post-process check deletes any asset whose pivot drifted, fail-secure.
- Separates bounded contexts: isometric code lives in its own namespace and UI may only talk to it through an IsometricToUIAdapter, never by referencing a SpriteRenderer directly, so the Screen Space UI never leaks into Y-sort logic.

-
Can I apply this to an existing project that wasn't started as isometric?
Yes, refactoring an existing project onto the iso diamond grid is a covered use case. The GameConstants single-source file and editor validators let you migrate scene by scene and catch grid or sorting violations on save instead of discovering them at runtime.
-
I can set PPU and camera settings myself, so what does this actually prevent?
Setting them once isn't the problem, drift is. The AssetPostprocessor enforces PPU, Point filter, and pivot on every import, and fail-secure validators check sorting layers and grid invariants on save. That's what stops jitter and blur from creeping back per scene.
-
Does this cover character animation or tile artwork too?
No. This is strictly the grid, PPU, camera, and sorting-layer foundation for 2.5D isometric projects. Animation pipelines and tile authoring are separate concerns, and it doesn't generate any sprite art for you.
