Isocraft 0.1.1 — The Playability Update

This is the major stability and playability pass since 0.1.0, focused on making normal survival, building, interiors, and caves dependable in isometric view.

Room and cave reveal

• Reworked room detection for open-front builds, partial walls, skylights, cave mouths, and irregular spaces.
• Doors, fence gates, and trapdoors now separate room transitions instead of letting scans spill through a structure.
• Large caves stay local to the player instead of exposing an entire connected cave network or letting distant daylight open everything.
• Improved cave boundaries, sightlines, and edge coverage to reduce black wedges, giant missing terrain regions, foreground walls, and accidental x-ray-like openings.
• Preserved nearby steps, walkable terrain, and the next downhill landing so the cutaway does not hide the wall or ledge being navigated.
• Fixed many cases where the player, mobs, beds, chests, crops, or foliage disappeared with the terrain cutaway.
• Large rooms now use the full configured scan budget, and reveal state resets cleanly after world or dimension changes.
• Reduced unnecessary chunk rebuilds during fast travel, rotation, zooming, and settled play.

Camera and controls

• Camera rotation is now continuous: hold , or . to rotate smoothly and release to stop at any angle.
• Rotation hitches are capped instead of replaying seconds of delayed input later; zoom input is also much more responsive.
• Removed automatic terrain collision zoom. Caves, buildings, ravines, falls, and landings keep the zoom distance selected by the player.
• Added an optional Movement Facing mode: face movement while travelling, then return to cursor aim while attacking or using.
• The isometric toggle now defaults to F8 to avoid Iris' O/K shortcuts. Exact old defaults migrate once; custom binds are preserved.
• Hold Left Alt to target above the player, or Left Alt + Shift to target below, without moving the camera.

Cursor and combat

• Added a small depth-aware cursor aperture, making block and mob edges easier to select without turning the cursor into a large aim-assist halo.
• Interaction rays now ignore unreachable camera-side foreground geometry, so blocks beside the character are no longer masked by blocks near the detached camera.
• Mining crops, bamboo, and other partial blocks stays latched to the intended block and no longer rolls onto the support block beneath it.
• Invisible and marker armour stands no longer steal the cursor on servers.
• Charged and charging crossbows now use the same lock and aim trace as bows.

Interface

• Walking away from an open container now closes it safely on the next tick, preventing crashes and stale close packets with UI mods.
• Container windows can be scaled independently from the rest of the GUI, from 35% to 200%.
• Compact settings layouts keep every option, preset, and the Done button reachable.
• Added a bindable 10-second clean Diorama GIF capture, bound to F7 by default.

Renderer compatibility

• Added renderer-specific vanilla, Sodium, and Iris reveal paths with safer rebuild, visibility, reset, and fail-open handling.
• Improved player, entity, and block-entity visibility and protected Iris shadow passes from the normal player-centred cutaway.
• Added shader safeguards for the transparency issue reported with Mellow and stopped crop and bamboo geometry from being treated like canopy foliage.

Known rough edges

• Vanilla rendering is the recommended experience for this release. Sodium and Iris compatibility is included, but those paths are still noticeably rougher and are actively being improved.
• Floor Aware is an unfinished experimental preview. In many layouts it currently falls back to ordinary Rooms behaviour and may appear to make no difference. Rooms remains the default and recommended reveal mode.

Versions

• This release artifact targets Fabric on Minecraft 1.21.11.
