Format notes

Scene

forger Package Scene (*.fpk)

This is the default forger format, it supports saving all scenes contents and states, including selections and tool preferences.

It is recommended that you remain in this format for as long as you can and use the more general export/import formats to interact with other mobile or desktop apps.

Geometry

Sculpting limitations

forger only supports two manifold meshes for sculpting, and it will show errors if any non-manifold mesh is attempted to load.

Non-Manifold meshes:

  • Can't be subdivided (with catmull clark).
  • Can't have their subdivision levels rebuilt

forger does not support importing of "invalid meshes" for sculpting, the following would be considered invalid meshes by forger:

  • Meshes with floating vertices (not in use by faces).
  • Meshes with "faces" that have less than 3 vertices.

OBJ (.obj)

forger only allows single object OBJ importing, multi-object importing will be added in future versions of the app. In order to import multiple objects from a single file whilst keeping them as independent geometry nodes in the scene once imported, the Alembic format must be used.

  • Import:
    • UVs (if found)
    • Geometry
  • Export:
    • UVs (if any)
    • Geometry

Alembic (*.abc)

forger has "basic" support of Alembic files, allowing the import of single frame meshes.

Only Ogawa Alembic files are supported

  • Import:
    • Sculpting: forger will import any sub-meshes as individual MultiresMesh nodes.
    • Painting: forger will merge all sub-meshes into one for painting purposes.

Sculpting

Shortcut Action
Ctrl Run alternate tool function (often negative)
Shift While pressed, the active tool is changed temporarily to the Smooth Brush

B While pressed, you can adjust the brush size by moving the cursor
M While pressed, you can adjust the brush strength by moving the cursor
W Changes the active tool to the Transform (Translation mode)
E Changes the active tool to the Transform (Rotation mode)
R Changes the active tool to the Transform (Scaling mode)
X Toggles symmetry for the currently selected Mesh (if any)
Cmd+D Duplicates the currently selected Mesh (if any)
Cmd+R Remeshes the currently selected Mesh (if any)
Shift+D Subdivides the currently selected Mesh (if any)
Cmd+Up Arrow Makes the currently selected mesh go one sublevel up
Cmd+Down Arrow Makes the currently selected mesh go one sublevel down

Painting

Shortcut Action
Ctrl While pressed, the active tool is changed temporarily to the Eye Dropper Tool
B While pressed, you can adjust the brush size by moving the cursor
M While pressed, you can adjust the brush strength by moving the cursor
J While pressed, a floating color picker will appear at the last known cursor coordinates, use this for quicker color picking
E (only available for the projection brush) press while moving the cursor to move the projection image
R (only available for the projection brush) press while moving the cursor to rotate the projection image
S (only available for the projection brush) press while moving the cursor to scale the projection image
D (only available for the projection brush) press while moving the cursor to squish the projection image
