Q: How does voxel size work?

The voxel size value refers to the number of horizontal pixels between voxels, so it is resolution dependent and low values mean higher detail.
The default is 5, which works reasonably well for most systems since resolution and GPU capability are often related. If you have a high resolution monitor on a low end GPU you may need to raise this value.
If you have a higher end GPU such any RTX or AMD >= RX 590 it should be possible to lower the voxel size value to, perhaps to 4 or 3.
At 4k resolution on Nvidia with voxel size at 3, I've noticed issues with high draw count, so to compensate, I'd recommend increasing the voxel patch size to 30 or 40(the default is 20).

Building forms is a core aspect of the game. You can build many different shapes, each with adjustable properties.

Shapes

There are hundreds of customizable shapes you can build, some procedural, some fractal, and some from baked distance fields

Mods

Mods allow you to further adjust shapes, some work on the space the shape exist within, some manipulate the shapes displacement

Ops

Ops control how the shape blends when applied to another shape

There are 15 ops to select from-with adjustable parameters

Spawn

To spawn a shape you will need the amount of material as determined by volume, you can always devour material from the environment if you are low

Optional Multiplayer

The game is playable singleplayer, but you may find it more enjoyable with friends.

Player Hosted Servers

Players may host servers, doing so gives them control over the specifics of the world they are hosting. Use the in-game editor to create custom rules for generating your world, and set the rules that goven your world

Coop or Competitive

You can choice to play cooperatively, building together, and exploring

There are no weapons, but it is possible to fight in an indirect way, throwing heavy objects at each other, or devouring one another

Persistant

The world is persistant; all shapes created, and all damage done is permanent.

If you create a rockslide that wipes out the forest below, it cannot be undone

If you devour all lifeforms capable of creating new materials, you may find your world rather inhospitable

Explore

Travel to different regions of the world; forests, snowy mountains, and deserts are available in the default world rules(Or use the in-game tools to make new rules and new biomes)

Learn

If you find an interesting formation, try devouring it, you may learn a new shape, mod or op depending on the formations composition

Devouring other players artwork may not be the best idea..

Clone

You can clone any shape or combination of shapes if you have required material and energy

Build Worlds

The same tools used by the devoloper are available to players. Use in-game editor to build custom rules describing shape clusters and distribution

Voxels

Everything in the game uses Voxels(as signed distance fields), all geometry is generated at runtime, allowing the game to scale to wide range of hardware

Voxel detail is fully adjustable, it has no effect on gameplay

Windows PC

The game will be available for Windows, and will run on any dx11 capable GPU

It uses a custom engine that is capable of scaling to all cores

Makes heavy use of wide SIMD with AVX2

There is a fallback for those with older CPUs(SSE2)

No Loading

There are no load times, the game boots and is playable nearly instantly.

Regular Updates

The devoloper will continue to update the game, and is interested in player feedback
