Welcome to Anterio. This is a hybrid of a professional CAD editor and an atmospheric sandbox. Here, you don't just place blocks — you work with geometry, vectors, and light physics. The program requires some getting used to, but it gives you complete control over space.
The entire world in Anterio obeys a mathematical grid. This guarantees that your walls will always join perfectly, without gaps or seams.
- Decimeter Grid (0.1 m) — [Standard]:
- Default mode.
- Cursor and objects "snap" to invisible nodes every 10 cm.
- Ideal for: Building walls, creating rooms, rough layout.
- Centimeter Grid (0.01 m) — [Hold Ctrl]:
- Press and hold Ctrl during any action (building, moving, resizing).
- Snap step decreases to 1 cm.
- Ideal for: Creating thin partitions, decor, eliminating micro-gaps, working with furniture.
The world is generated in chunks (sectors) as you move.
- The Global Grid on the ground is drawn only around you (for optimization), but you can build anywhere — coordinates are infinite.
Instant switching via the [TAB] key.
- You are the Architect. The camera flies freely through walls (noclip).
- Interface: HUD is enabled with tooltips, coordinates, and object dimensions.
- Visualization: Bright daylight. Linear fog (helps feel depth but doesn't obstruct view).
- Interaction: Doors open via Alt + RMB.
- You are the Explorer. Body physics is enabled. You cannot pass through walls; gravity pulls you down.
- Lighting:
- Lamp: A soft glow (light aura) is created around the player, illuminating the path.
- Light radius adjustment: Mouse Wheel.
- Interaction: Doors open with a normal LMB click.
Special mode for adjusting time of day and lighting.
- Enter/Exit: Press [Ctrl + E].
- Up/Down Arrows: Change time of day (sun movement across the sky).
- Left/Right Arrows: Rotate sun orbit (change cardinal directions).
- Ctrl + Arrows: Change Time Speed.
- W / A / S / D — Move (Fly / Walk).
- Space — Fly Up (Creative) / Jump (Adventure).
- Shift — Fly Down (Creative) / Crouch (Adventure). In Adventure mode, makes steps silent and lowers the camera.
- Ctrl — Sprint / Fast Fly.
- Mouse Wheel — In Creative mode smoothly changes base camera flight speed; in Adventure mode adjusts flashlight brightness.
- C — Switch to Cine-Cam mode (see section 9).
- F11 — Fullscreen mode.
How to select: Press numbers [1]...[6] and [7]. How to exit: Press [Esc] to drop the tool and return to Select mode.
💡 Key Mechanic [Q]: When using tools, a "ghost" object is built. Press [Q] to change the construction plane or constraint axis (e.g., to draw vertically instead of on the floor).
Simple tool for erecting partitions.
- Click 1: Start of wall.
- Click 2: End of wall.
- Result: Wall is created with thickness specified in settings (Menu -> New Wall Thickness).
Create monolithic blocks (foundations, stands, solid buildings). Has two modes:
- "Base + Height" Method:
- Draw a rectangle on the floor (Click 1 → Drag → Click 2).
- Release mouse and pull cursor up.
- Click 3rd time to fix height.
- "3D Diagonal" Method:
- Click point A in space (e.g., floor corner).
- Click point B (e.g., opposite corner under the ceiling).
- Block is created instantly between these points.
Works exactly like the Box tool (same two methods) but creates hollow objects:
- Generates: Floor, Ceiling, and 4 Walls.
- Wall thickness is taken from settings.
Drawing walls by points (polyline mode).
- Click LMB to place nodes. "Smart corner" logic is active.
- RMB — Remove last placed point (Undo).
- Closing the loop: Click exactly on the very first point. The contour closes, corners automatically "weld" without gaps.
- Finish: Double click (or press Enter) to finish drawing an open wall and extrude it upwards.
- Smart Angle: If you approach the start point at an angle (not straight) when closing the loop, and aren't holding Ctrl, the tool automatically creates a diagonal corner piece so the wall doesn't look "squashed" in the corner.
Tool for quick voxel modeling and volume subtraction.
- RMB (Right Button): Add cube. Snaps to surface of other objects.
- LMB (Left Button): Cut cube (Boolean Cut). Creates a recess in the object.
- Brush Sizes:
- Standard: 1 dm (10 cm).
- Shift: 0.5 m (Large block).
- Ctrl: 1 cm (Detailing).
Powerful boolean operation tool (subtraction).
- Windows and Doors: Hover over a wall. Click two points diagonally — an opening is created.
- Basements and Pits: Click two points on the ground (not on an object). A hole is cut in the terrain through which you can fall.
- Through Cut ([Alt]):
- Hold [Alt] while creating a cut.
- The hole cuts not only into the block you are looking at but also through all blocks behind it (or touching it). Ideal for punching passages through thick walls or groups of objects.
Laser knife for cutting objects into parts.
- Hover over an object. A cut plane appears.
- Auto-orientation: The knife understands if you are cutting a floor or wall and aligns perpendicularly.
- [Q]: Switches cut direction (longitudinal/transverse) if auto-selection isn't right.
- Click LMB — Slice object. Now it is two independent halves.
- [Alt] + Click — Slice the entire group of objects or all objects on the cut line.
There is no ready-made "door" object in Anterio. You can turn any block (or group of blocks) into a door.
- Select tool [T].
- Hover over a block (or grouped object).
- Select Axis: Move cursor near the edge where hinges should be. The edge highlights purple.
- Note: You can choose vertical edges (door) and horizontal edges (hatch).
- Fix: Press LMB. The axis becomes red (locked). Now you can rotate the camera and check if the axis is chosen correctly.
- Mistake? Press Esc to reset axis selection (returns to purple highlight).
- Create: Press Enter. The object becomes an interactive door.
- Group Doors: First select multiple blocks (handle, panel, glass) and group them [G]. Then apply tool [T] to this group. The whole structure will rotate as one.
- Remove Properties: Select tool [T] and click on a finished door. It becomes a normal static wall again.
- Fix (Ctrl + T): If the door opens the wrong way or is out of sync: exit to selection mode (Esc), select the door, and press Ctrl + T. This inverts its state.
- Alt+RMB in Creative Mode - to open/close.
- LMB in Adventure Mode - to open/close.
Press [X] to open the materials panel on the right. In this mode, the camera unlocks for UI interaction.
- HSV (Hue, Sat, Val): Color adjustment.
- A (Alpha): Transparency (0 = invisible, 1 = solid). Use for glass.
- E (Emit): Glow strength. In Adventure mode, such blocks emit light.
- G (Gloss): Gloss/Shine. Determines reflections from sun and lamps.
- D (Dens): Density and Physics.
- 1.0: Solid block.
- 0.25 ... 0.99: Liquid (Water). Player swims in this block, movement slows, gravity weakens.
- <0.25: Ghost/Gas. You can pass freely through the block.
- M (Mirr): Mirror. Turns surface into a mirror (affects performance!).
- "Full" Checkbox (Paint Entire):
- On: Paints the entire cube.
- Off: Paints only one face. (To select a face, in Select mode use Ctrl + Click on the face).
- "Tile" Checkbox: Enables texture repetition (tiling) instead of stretching it over the whole face.
- "Load Texture" Button: Load image (.png, .jpg, .gif) from disk. Supports animated GIFs!
- Ctrl + X (Eyedropper): Hover over a block in the world and press to copy all its properties (color, texture, physics) to the palette.
- Double Tap [X]: Instantly apply current palette settings to the selected object without opening the menu.
While materials window [X] is open and a textured object is selected, you can move the image on the surface:
- W / A / S / D: Shift texture vertically and horizontally.
- Arrows: Stretch and compress texture (tiling).
- Shift + Keys: Fast change.
- Ctrl + Keys: Precise adjustment (slow).
- [R] / [F]: Rotate and flip texture (works same as objects).
At the bottom of the materials panel are colored rectangles ("chips"). This is the history of your last used settings. Click any of them to instantly restore that color and properties.
This is the main working mode (like in CAD systems). Press [Esc] to switch to it from any tool.
- Simple Click LMB: Selects one object.
- Ctrl + Click: Add object to selection or remove from it.
- Selection Frame (Hold RMB + Drag Mouse):
- 🟦 Blue Frame (drag left-to-right): Selects only objects that are completely inside the frame. (Logic "Inside").
- 🟩 Green Frame (drag right-to-left): Selects everything the frame even touches. (Logic "Touch").
- Move (Keyboard Arrows):
- Arrows move object along active axis.
- [Q] — Change active movement plane. Switches between axes X, Y (Vertical), and Z.
- Scale [E]:
- Press [E], then press arrows (works like Push/Pull).
- [Alt] + Arrows: Uniform scaling of object in all directions (from center).
- Delete: Delete key.
- Ctrl + Z: Undo last action.
- Ctrl + Y: Redo cancelled action.
In Anterio, rotation happens strictly along axes.
- First select transformation axis by pressing Ctrl + Q (or just Q). At the bottom of screen, you will see tooltip: Axis X / Axis Y / Axis Z.
- [R]: Rotate selected 90° around selected axis.
- [F]: Flip mirror-wise along selected axis.
- [G]: Group selected. Objects will be selected with a single click.
- [G] (again): Ungroup (if an existing group is selected).
- [C] (Combine): Attempt to physically combine (weld) two selected cubes into one.
- Ctrl + C: Copy selected to clipboard.
- Ctrl + V: Paste. Object "hangs" on cursor. It smartly snaps to surfaces.
Anterio automatically shows dimensions (X/Y/Z) of selected object. However, you can use selection tools as a tape measure to measure distance between objects.
How to measure distance between two walls:
- Go to Select [Esc] mode.
- Hover cursor over first face, click LMB (face highlights with blue grid).
- Holding Ctrl, click on second face on another object.
- When exactly two faces are selected, a colored line stretches between their centers showing exact distance and axis offset.
Press [Esc] (if nothing is selected) to open Pause/Menu.
- New Wall Thickness: Slider sets wall thickness for new objects.
- Fog Distance: Draw distance and fog.
- FPS Limit: Frame limiter (On/Off).
- Save / Load: File manager. Supports project formats
.ant,.zip,.json. - Export 3D: Export your scene to popular 3D formats (.obj, .glb, .stl) for use in Blender, Unity, or 3D printing.
- Ctrl + Alt + S: Quick save directly in game.
- Language: Interface language switch button (English / Russian).
