Version 6 "Rock and Stone" - Detailed Release Notes
2 November 2025
You can also consult a shorter summary.
Generated structures: houses and towers
- Added generation of structures, such as desert houses and towers of the Air.
- Upon generation, structures can remove naturally placed blocks and entities and add their own blocks and entities.
- Three new block materials: whitestone, blackstone, and wood.
- Loot entities are generated inside the structures according to predefined probability distributions.
- Houses have supporting columns and the entrance staircase that adapt to the exact landscape shape below and in front of the house. The staircase can be in one of the two directions.
- Books and scrolls now only generate within structures.
- Their content is random, but follows predefined probability distributions. For example, books generated in towers are of a higher level than those generated in houses.
Improved terrain generation
- Switched to a new biome: "Canyons". Instead of gray rock and green grass, it features two new terrain materials: packed red sand and desert stone.
- Full rework of the terrain generation.
- Added support for landmarks: extra-large scale objects such as mountains or canyons.
- Added support for very steep slopes.
- Dual-matter terrain generation. The stone is generated 2 blocks under the sand, following the same surface shape.
- The basic terrain is now less smooth and also has more fine-scale variations (at a scale of dozens of blocks instead of hundreds).
- Added terraces, creating an interesting mix of cliffs, flat valleys, and plateaus.
- Added long canyons that can stretch across several hundreds of blocks.
- Improved blocks.
- Support for dual-matter blocks (e.g., rock and sand).
- Support for complementary blocks (i.e., partial block forms that fill the remaining block volume with respect to the previously existing partial block forms).
- Increased the number of the block forms from 46 to 106. They now represent all possible rotations and mirror reflections of various combinations of single and double slopes.
- New entity: stone. Stones have 16 random variations, differing in shape and size, but using the same texture. Stones are generated randomly across the terrain.
- New chunk generation algorithm that guarantees the same result regardless of the direction the players come from to a given chunk.
- Improved vertical positioning of entities at generation. There are less overhangs and entities are buried less deeply into the ground on steep slopes.
Magic
- 3 new scrolls: "air pull", "stone bridge", and "draw from gems".
- The "air pull" spell allows you to throw yourself into the air, as the Air wizards. Beware, though: landing may be a bigger problem than flying.
- The "draw from gems" spell allows you to use energy stored in gems for your spells, if you carry one of them with you.
- The "stone bridge" spell fills a small area in front of you with desert stone.
- The cost of most spells has been reduced by a factor of 5.
- The "extract" fragment cost is now minimal.
- The "extract" and "store" fragments now only work on nearby gems.
- 2 new spell fragments: "select position around" and "is selected".
Gameplay
- Improved jumping. Now, rotation near an obstacle will not push you away.
- When hitting an obstacle, entities now rebound a little bit.
- It is now possible to break dual-matter blocks in two steps, removing first one matter, and then another one.
- It is now possible to complete dual-matter blocks (partial implementation).
Graphics and UI
- Increased the vertical render distance to match the horizontal one. This was necessary to properly draw the terrain with a lot of vertical features like peaks and cliffs.
- Improved drag-and-drop [feedback based].
- The dragged item is now being shown. When applicable, the dragged item includes the icon and the text. For spell fragments, it also includes their parameters.
- The original item position is grayed out.
- The compatible drop locations, including containers, in-hand slots, hotbar slots, and so on, are highlighted.
- Improved UI: the chosen item, such as a spell in the list of spells, or a magic discipline, is now highlighted. It makes it clearer what item is described in the opposite interface pane. For a spell fragment, both the fragment and its parameters are highlighted.
- Added support for mouse wheel in hotbar [feedback based].
- Mouse sensitivity option (from 1% to 1600%).
- Field of view option (the vertical FOV range is from 15 to 150 degrees). The horizontal FOV value is also shown.
- Expanded the tutorial message. It now mentions the keys for run lock and for lying down.
- The main menu now has links to Discord and Reddit.
Optimizations
- Required chunks are now prefetched ahead of time in a worker thread. This reduces staggering when some chunk boundaries are crossed.
- Fully reworked the shadow save mechanisms to account for the newly added prefetch mechanism.
Bugfixes
