Convert FLI_ to FLT

Understanding FLI and FLT file formats

FLI files are animation files created by Autodesk Animator, a popular animation software from the early 1990s. The FLI format stores frame-by-frame animations using a palette-based color system, making it efficient for simple animations and sprite work.

FLT files, on the other hand, are most commonly associated with OpenFlight, a 3D scene description format developed by Presagis (formerly MultiGen-Paradigm). FLT files are widely used in simulation, visualization, and modeling applications, especially in the defense and aviation industries. They store 3D geometry, textures, and scene hierarchy information.

Can you convert FLI to FLT?

Direct conversion from FLI (2D animation) to FLT (3D scene) is not straightforward, as these formats serve fundamentally different purposes. FLI is for 2D animations, while FLT is for 3D models and scenes. However, if your goal is to use FLI animation frames as textures or image sequences in a 3D FLT scene, you can extract the frames from the FLI file and then apply them as textures in a 3D modeling tool that supports FLT export.

How to convert FLI to FLT

1. Extract frames from FLI: Use a tool like FFmpeg or IrfanView to convert the FLI animation into a sequence of image files (e.g., PNG or BMP).
2. Import images into a 3D modeling tool: Use a 3D modeling application such as Presagis Creator or Blender (with FLT export plugin) to create a 3D scene. You can map the extracted images as textures onto 3D planes or objects.
3. Export to FLT: In your 3D modeling tool, use the export function to save your scene as an FLT file. For example, in Presagis Creator, use File → Export → OpenFlight (.flt).

Recommended software for FLI to FLT conversion

• FFmpeg – For extracting frames from FLI animations.
• IrfanView – For batch converting FLI frames to image files.
• Presagis Creator – Industry-standard tool for creating and exporting FLT files.
• Blender (with OpenFlight export plugin) – Free and open-source 3D modeling tool that can export to FLT with the right add-ons.

Summary

While there is no direct one-step converter from FLI to FLT, you can extract FLI animation frames and use them as textures in a 3D scene, then export the scene as an FLT file using specialized 3D modeling software.
