Convert FLT to FLI_

Understanding the flt and fli file formats

FLT files are typically associated with OpenFlight, a widely used 3D scene description format developed by Presagis. OpenFlight (.flt) is popular in simulation, visualization, and modeling industries for storing complex 3D models, including geometry, textures, and scene hierarchy.

FLI files, on the other hand, refer to Autodesk Animator FLI Animation files. The .fli format is an early animation file type that stores frame-by-frame bitmap animations, commonly used in the 1990s for simple animated graphics.

Why convert flt to fli?

Converting a FLT 3D model to a FLI animation file is an uncommon but sometimes necessary process, especially if you want to create a simple animation from a 3D scene for legacy software or retro game development. The conversion involves rendering the 3D model into a sequence of images and then compiling those images into a FLI animation.

How to convert flt to fli

There is no direct one-step converter from FLT to FLI due to the fundamental differences between 3D models and 2D animations. The process generally involves two main steps:

1. Render the FLT 3D model to image frames: Use a 3D modeling tool that supports OpenFlight, such as Presagis Creator or Blender (with plugins), to open the .flt file. Set up your camera and animation, then render the animation as a sequence of images (e.g., PNG or BMP).
2. Convert image sequence to FLI animation: Use a tool like FFmpeg or ImageMagick to convert the image sequence into a video or animation format. Then, use a specialized tool such as Animake or FliCreator to compile the image sequence into a .fli file.

Recommended software for flt to fli conversion

• Presagis Creator: For opening and rendering FLT files.
• Blender: With the appropriate plugin, Blender can import FLT files and render animations. Use File → Import → OpenFlight (.flt) and Render → Render Animation to export image sequences.
• Animake: A classic tool for compiling image sequences into FLI animations.
• FFmpeg: For converting image sequences to video formats if needed before FLI conversion.

Step-by-step conversion process

1. Open your .flt file in Blender or Presagis Creator.
2. Set up the desired animation or camera movement.
3. Render the animation as an image sequence (e.g., PNG files).
4. Use Animake to import the image sequence and export as a .fli file (File → Import Images, then File → Export → FLI).

Conclusion

While there is no direct converter from FLT to FLI, the process can be accomplished by rendering your 3D model to an image sequence and then compiling those images into a FLI animation using specialized tools. Blender and Animake are recommended for this workflow.
