MarchingBlocksFAQ and limits
Honest limits
- Windows only for now (Windows 10 or 11, 64-bit, a Vulkan graphics card). macOS and Linux may come after 1.0, if people ask for them.
- Early Access: the tool is complete in features, but young. It was built and tested by one developer, with thousands of automated checks, but few hands have used it on real projects yet. Expect rough edges, and tell us: reports are fixed first.
- An atlas carries no unique detail: a tile sculpted in one place comes back everywhere its shape comes back. That is the point of tiles — and variants are there to break the repetition.
- Do not send the witness to an automatic texturing tool that paints it as one object: it looks perfect in the block and breaks at every seam of the world.
- The plugins are young too: they pass their test cases, and what each one does is listed on the plugins page. Water is computed by the app, not in the engine.
- The installer is not code-signed yet: Windows SmartScreen may say "Windows protected your PC". Click "More info", then "Run anyway". The file you download from your downloads page is the one we built.
- A plant does not follow the ground if you dig under it later.
The software
Is there a free demo?
Yes, from launch day: the whole software — every workshop, the example world, the Play test — but it does not save your project, open your own files or export. Its data stays apart from the full version.
Do I need Blender?
No. The Geometry workspace is a modeller with Blender's gestures and shortcuts, and Texturing paints in 3D. Blender is there if you prefer it: export the witness as one .glb, sculpt it, bring it back.
Which engines?
Godot 4, Unity 6 and Unreal Engine 5, through the free MarchingBlocks Paint plugins. The open format can be read by any other engine or tool.
Can I sell games made with it?
Yes. The tiles, worlds and everything you make with MarchingBlocks are yours, commercial use included, with no royalty and no obligation to credit us. The example content may be used in your creations, but not resold on its own.
How do updates work?
The website version checks at launch whether a newer version exists (you can turn this off in Project). If one does, the title bar says so; nothing downloads by itself. Your downloads page has the new installer, which replaces the old version and keeps your projects and settings.
Does MarchingBlocks collect data?
No. No telemetry, no account. The update check only reads a public file on this website; like any connection, it shows your IP address to our host. See the privacy policy.
Is AI used?
MarchingBlocks itself generates no content with AI. The app's splash screen and icon were created with the help of an AI image and 3D tool (Tripo) and then edited, and two screenshots show AI-generated trees imported into the Foliage workshop. Everything else — the software, its interface, every world and screenshot — is made and captured in the real software.
How do I report a bug?
Write to contact@spannergames.com, with what you did and what happened. The developer reads every report.
