File I/O

forger allows full interoperability with other platforms and 3D packages by allowing you to import/export models from/to it at any given time.

In addition to working from the base meshes supplied with forger, you can export other meshes from any traditional desktop 3D package. Also, the app lets users import polygonal geometry files in the very common Wavefront OBJ format and the industry standard geometry format Alembic.

The "Home" menu allows you to open forger scenes, as well as importing geometry files.

If incremental versions of a scene have been saved, they will show up as photo stacks and will allow choosing which version to import.

Scenes prior to 2019 may not have an associated screenshot within them, they can still be opened though.

The contents listed in this menu correspond to the contents of the "Documents" folder of the app, these contents can also be browsed and edited via the Apple "Files" app.

Note

forger filters out any non-scene files from this list to avoid user confusion.

All file I/O in forger is done locally on the device and not to any cloud locations due to the large size of files it can manage.

forger scene files can store many multi-resolution meshes per file, along with materials and tool preferences. (they have the *.fpk extension)

Note

There is no hard limit set that defines the maximum amount of meshes that are allowed in a scene, the only restriction is that their combined memory usage fits within what iOS allows the app to use whilst running in the device.

Users can import as many meshes as needed into a scene, and change the current mesh selection from the "Objects" menu as usual.

Import

Opens the import dialog which allows you to choose among various types of data to import.

Save

Allows saving the current scene to open later as it is, with all its contents, including selection, masks and tool preferences.

  • Save: stores the current scene with the last scene name it was given or if there isn't a scene name with the current selections scene name.
  • Save Incremental: Increments the "name" a previously saved scene, e.g. for mySceneName.fpk it would save as mySceneName1.fpk, and so on.
  • Save As...: Gives you the ability to save the scene with an adequate name so it's easier to remember what the contents are. It is recommended using this first and then using the other two in successive saves to avoid you from typing a similar or identical scene name all the time. ;)

Export

Allows exporting the selected geometry to various file formats.

3D Model

Texture

Render

Turntable

forger allows you to make turntable videos of their creations.

You can choose the length (in frames) of the turntable videos.

Render

forger allows taking screenshots with alpha that you can later on use in other programs to do concept work on the go. This action is preferable to just using raw screenshots and keying out the background.

This function allows you to pick a resolution between: 720p, 1080p and 2160p.

Screenshot

This action will take a screenshot of the viewport.

Autosave

By default forger will automatically save scenes when the app is moved to the background (if you press the home button or some other app takes over, unless it detects that the scene is "too heavy" to autosave. If forger detects that this is the case, it will show an informative message. This is because there is a restriction in iOS that limits the amount of time that an app can spend having background activity after moving to the background, heavier scenes will take longer to save so forger may decide to disable autosave for them. (Note that users will always be notified of this option being disabled).

Note that all of this depends on the "Autosave Scene" setting, found in the Preferences menu that defines whether scenes are auto saved or not.
