Build 4011 'Mt Rainier' Release Candidate available

World Machine LTE

‘Mt Rainier’ Release Candidate

Build 4011

Welcome to the third development preview for the ‘LTE’ series of World Machine! This next-generation version modernizes World Machine and migrates from its original GUI platform. Build 4011 is likely to be the last release before the LTE branch becomes the standard Release version of World Machine.

The only anticipated remaining changes are bugfixes and content.

What’s New in LTE?

Here’s a high-level overview of what’s new:

  • Progressive, high-resolution background builds
  • Complete, granular edit history retained; jump into the past in your edit history to compare changes
  • Edit multiple non-modal parameter dialogs at once
  • Multiple, resizable viewpanes
  • Retain settings ‘snapshots’ of important builds
  • Devices and macros have greatly improved presentation of parameters (styling, grouping, etc)
  • Full-skin darkmode UI
  • Hit TAB to quick-add a device or macro from search
  • Greatly improved high-resolution terrain display
  • Maya-style ALT navigation in all viewports
  • Tiltable orthographic layout view

There are in addition many hundreds of smaller changes and improvements beyond the above.

Changes since Build 4008

These are the changes introduced since the last dev build 4008

New Features

  • Clicking on a port or wire now selects that output for viewing!
  • Parameter devices now accept distance and elevation parameters. This is very useful for macro creation
  • Open from Example Library now shows a 3D preview for the world being opened!
  • Added (optional) automatic snapshot creation on export / tiled build
  • Added tag support for devices, macros, blueprints. You can add tags to your macros and blueprints that they will match for. This will also allow for neat grouping/filtering in the future by tag.
  • Macros now save their presets to the Presets folder. Macros could also still save their presets into the macro itself, which is useful for distribution. There is currently no easy way to set this.
  • Added Device Version manager dialog that lets you update all devices in a world to the latest version (and see any issues involved in doing so)
  • Virtually all device versions now have update warnings as appropriate.
  • Explorer render extent management is much improved
  • Leftside-toolbar is now a dockwidget, and can be floated out of the main viewport
  • Autosave is now asynchronous, saving 15-100ms on UI thread every action
  • 2D view creates output asynchronous, saving massive lag on UI thread
  • Finally ironed out the correct building and viewing of devices inside a macroworld in essentially all scenarios (improved from build 3028, where sometimes devices inside a macro could not be reliably edited or viewed)
  • You can now set a default output for a world or macro. This lets you do things like, for example, have a Scene View inside a macro that will show the result of a terrain+texture combo even if the macro just exports a texture.
  • Filter by version now works in library dialog
  • Select Wetness, Flow Restructure, and Create Water all now report progress and are cancellable. This is particularly important in LTE as a non-cancellable device causes the background preview engine to be far less responsive when the world contains one of those devices.


  • Device tags added for finding “Splatmap” and “Layout Generator”
  • Texture Weightmap device: Added “Material ID” mode. This assigns each point in the world a single material instead of producing weightmaps.
  • Updated Create Water UI parameters to LTE
  • Several new macros added showing the expanded capabilities of the LTE macro system; For example, the ‘Ambient Overlay’ macro

Features From legacy World Machine Reimplemented

  • Added a * marker to the window title when project is modified :slight_smile:
  • Added tile build resolution/mem required readouts
  • Macro presets are now loaded properly.
  • Basic explorer view is re-implemented
  • Session support re-implemented. Currently, sessions are how you can retain all of your history state, in a seperate state file. You can turn it on and off in project settings->general


  • Asset Export dialog now enforces only a single instance at a time.
  • Autosave properly shows the restored file path when loading after a crash
  • River properties now has scrollbar
  • Zoomed pane gets a highlighted border
  • Toolbar pane toggle button now toggles mode instead of zooming pane
  • Added “browse” button to Library load dialog that lets you open a world/macro/blueprint from any location, not just your library folder
  • Minor improvements to preset ergonomics; the way that the "Preset* " modified naming system works on load/save/delete is improved
  • Added old version importer to Displacement, Curves, improved River
  • When changing device version, now always run the conversion code instead of only the first time
  • Asset Export, Device Upgrade are now nonmodal dialog views that persist through multiple projects
  • When you open a file using Recent or Open File, the next time you open a file you will start in that folder
  • Views now release scenes when they are not visible, reducing memory usage
  • Param dialogs only now doc to left/right side
  • System info dialog improved
  • Project Settings now has a scrollview to accommodate more settings
  • Checkpoint automatic naming is improved to work like the Library Output
  • Basic Perlin gradient parameter now displayed in degrees. This should not break existing worlds.
  • Parameter values on mouseover in workview and param designer are more specific (elevation, rgba value, etc)
  • Improved library dialog sorting
  • Added logging for failure to load macros/blueprints
  • Ctrl+click on a port lets you wire from it like before.
  • Ctrl+drag on a render extent in explorer lets you drag the extent. Dragging was disabled by default as it often was accidental.

  • Fixed parameter reordering bug, where you the reorder destination would be off-by-one
  • Create Water specified headwaters UI works again (oops)
  • Fixed bug where macro presets were corrupting device IDs
  • Fixed project browser view target

Known Issues / Remaining to Implement

  • Modernize Tiled File Input dialog
  • Layout shapes minor features (vertex welding, gridsnap)
  • Error feedback messageboxes still need a scrollbar when too many to fit on a screen

Just a minor update: As of right now, 7:12PST 11/16/2020, The installer has been updated to 4011.2. This is very small fix that solves three issues:

  1. Crash when startup.tmd is blank
  2. Advanced perlin device’s custom fractal profile wasn’t saving
  3. Version string not correct in Indie Edition

If you check Help->About, you can see if you are running the latest and update if necessary.
