Changelog

Improvements

• added missing Object Frequency Constraints: These constraints allow you to specify, for a building block, how often a particular (other) building block may appear in the immediate vicinity, along the axes, or in a defined direction.
• added direction freqency constraints: These constraints specify how often the same or any other building block may appear in a defined direction.
• improved noise constraints: All noise functions are now available, along with their customisable parameters.
• added some new parameters to the geometry nodes for the feature that displays directions in the 3D Viewport
• improved frequency constraints performance
• improved the WFC 3D Constraints Editor:
  • added a "Reset to default" button for numerical values
  • added the "Generate WFC 3D Model" button to the WFC 3D Constraints Editor
• improved example blend files: The target has now been set to an object rather than a collection.

Bug fixes

• fixed axis frequency bug: now only neighbors are counted
• fixed geometry nodes bug related to "show directions in the 3D Viewport" feature and 5.x API changes
• fixed example files related to the axis frequency bug fix

Changelog

• improved geometry constraints dialog
• add missing relationship line toggle to WFC Generator panel

Changelog

• fixed some minor bugs and tooltips

Changelog

• added target object feature:
  • Instead of a target collection, a target object (Empty) is created.
  • This makes it easier to transform the generated object (move, scale, rotate).
  • In addition, when placing the target object using the cursor, not only the position but also the rotation of the cursor is now taken into account.
• The target object or target collection is now created in the active collection instead of in the root collection.

Changelog

• improved UI:
  • added missing placeholders, tooltips, and search functions
  • fixed list filter bug
• improved WFC 3D Generator:
  • added missing rendering statistics
• fixed minor import/export bugs

Changelog

• improved region probability constraints: constraints order matters and allows overlapping regions
• improved WFC 3D Generator UI
  • changed UI layout for grid size, odd offset, location input fields to save space
  • added cursor location feature: You can use the 3D cursor for the render location.
  • added Outliner action buttons to source and target collections
  • added some practical numbering operators to target collection name input
  • added a button to set a random random seed
• improved WFC 3D Constraints Editor:
  • added copy constraints feature: This allows you to copy constraints from an object to all selected objects.
  • The constraints editor layout has now been harmonized.
• improved WFC 3D Rotation Tool: added missing empty neighbor constraints rotation and dimensions constraints rotation
• improved WFC 3D Random Seeds UI: entries are now collapsed by default
• added WFC 3D Random Seed Search: This allows you to search for suitable seeds using advanced criteria.
• fixed some typos and bugs

Changelog

• improved cherry picking feature: added random seed bookmark feature: Seeds can be saved as bookmarks.
• improved WFC 3D Rotation Tool: added missing connector exclusion constraints rotation and multiple connector constraints rotation
• improved WFC 3D Generator:
  • It is possible to specify the entropy calculation method.
  • Performance data (number of cells, empty cells, generation time, rendering time, and total time) is now displayed.
  • In addition, statistics on the building blocks used are displayed.
  • Now the location can also be specified.
• improved probability constraints: Multiple connector constraints and connector exclusion influence the weight during automatic weight determination.
• fixed probabilty constraints bug: automatic weight determination works again
• fixed WFC 3D Validator: (multiple) connector constraints verification now also works with “any...” directions
• fixed some minor bugs related to noise constraints

Changelog

• added multiple connector constraints: define a list of allowed connector names for a specific direction
• added connector exclusion constraints: define a list of connector names that are not allowed for a specific direction
• improved fixed position constraints: allow percentage-based relative positions
• improved distance from position constraints: allow percentage-based relative positions
• improved seed search: allow to stop the search
• improved WFC 3D Constraints Editor UI: added a new list function: invert selection
• added background process feature for large models (>3000 cells)
• fixed frequency constraints bugs

Changelog

• added empty neighbor constraints: These constraints prohibit empty neighbors.
• improved region constraints: added level (floor) constraints
• improved geometry constraints: allows threshold value change
• improved position and region vector handling: allows relative positions to grid size
• improved delayed rendering performance: empty cells are now skipped
• improved WFC 3D Generator: auto-detect grid spacing
• improved WFC 3D Constraint Editor UI: added select all/none buttons to all lists
• improved WFC 3D Generator UI: added a progress indicator
• allowed grid size values largen than 100
• added online help to the WFC 3D Editor
• added constraints reset to the WFC 3D Constraint Editor + WFC 3D Backup
• fixed bug: dimensions constraints combined with symmetry constraints work again
• added a new example to GitHub: Towers (Preview)

Changelog

• added distance constraints: Rules that restrict the placement of building blocks based on their distance from a specific point or another building block.
• improved (region) frequency constraints: added percentage value
• improved noise constraints: randomized starting position
• improved backup tool: added replace constraints feature
• fixed backup tool: strings are now exported correctly

Changelog

• added geometry constraints: Edges or faces are used to determine whether two objects can be placed next to each other.
• added region probability constraints: These constraints increase or decrease the probability of an object being selected at random in a specific region.
• added a constraint backup tool: Import/Export all WFC 3D Generator constraints to/from a JSON file.
• added a rotation tool: Copies and rotates an object along with its adjacency constraints.
• improved neighbor/connector constraints: added any faces, any edges, and any corners constraints
• improved validator: added a "clear log" button

Changelog

• added region frequency constraints: Define any regions with permitted frequencies for a building block.
• added noise constraints: Noise constraints either influence the probability of an object occurring or replace random values in transformations with noise values.
• added random seed search feature: Search for a random seed with maximum grid occupancy.
• improved fixed position constraints: Now, any number of fixed positions can be defined for a building block.
• fixed delayed rendering: works again.

Changelog
