Shape File Manager (SFM) v2.5 is a specialized utility for Microsoft Train Simulator (MSTS) and Open Rails users to perform direct, simple edits on 3D shape files (.s files) without needing full 3D modeling software. Core Capabilities

The primary function of SFM is to bridge the gap between complex 3D exports and final game implementation. Key features include:

Compression & Decompression: Compresses or uncompresses .s files to make them human-readable for manual editing or to save space for the game engine.

Scaling: Adjusts the size of an object along the X, Y, and Z axes independently. Transformation: Reverse: Rotates an object 180 degrees about its Y-axis.

Rotation: New in v2.5, it allows for 90-degree clockwise or counter-clockwise rotations.

Shifting: Moves the model's position relative to its origin/pivot point. Visual & Performance Tuning:

LOD Adjustment: Modifies distance levels to control when objects appear or disappear in-game.

Texture Modes: Changes lighting modes for matrices, including a "specular fix" for shiny locomotives.

MIP Maps: Configures MIP Map levels for better texture rendering at distances. Installation & Troubleshooting

Setup: It is typically distributed as a .zip file. The contents should be unzipped into a dedicated folder (e.g., C:\Shape File Mgr\). Execution: SFM runs as an HTA (HTML Application) file.

Note: If it fails to open, you may need to right-click sfm25.hta and ensure it is set to open with the Microsoft (R) HTML Application host rather than a standard web browser.

Dependencies: It requires ffeditc_unicode.exe (found in the MSTS UTILS folder) to handle the compression/decompression tasks. Usage Tips

Uncompress First: Most editing options (like scaling or shifting) only work after the file has been uncompressed.

Editing: The utility includes a configurable Unicode editor for manual changes to .s and .sd (shape definition) files. Elvas Tower: Shape File Manager 25

Mastering MSTS Shape File Manager v2.5: Your Essential Guide

If you’ve been deep in the world of Microsoft Train Simulator (MSTS) or Open Rails, you know that 3D modeling can sometimes be a hurdle. Whether you need to resize a locomotive or fix a texture, you don’t always want to fire up a full 3D modeling suite. That’s where Shape File Manager v2.5 (SFM25)

comes in—a lightweight, indispensable utility for making quick, powerful tweaks to

Revised by Huecuvoe from Paul Gausden's original version, SFM25 remains a staple for content creators and route builders. Here’s everything you need to know to get it working. Key Features of Version 2.5

Unlike basic compression tools, SFM25 allows for surgical edits to your shape files: Compress/Uncompress : Easily toggle files between binary and text formats using FFEDITC_UNICODE.EXE Scaling & Shifting

: Resize objects across X, Y, and Z axes or shift their origin points—perfect for fixing "floating" objects. Rotation & Reversal

: Flip objects 180 degrees or rotate them 90 degrees clockwise or counter-clockwise. Texture & LOD Tuning

: Adjust MIP map levels, distance levels, and texture lighting modes (including specular fixes for shiny locos). Integrated Editing

: Configure your own Unicode editor (like Wordpad or Notepad++) to edit shape definitions directly within the app. How to Install and Run

SFM25 is an HTA (HTML Application) file, which means it runs through the Windows scripting host. : You can find the latest version on community hubs like Elvas Tower Extraction

: Unzip the folder into any directory. Some users find success placing it in its own subfolder within their main MSTS directory. : Double-click

. If you receive a "not a valid Win32 application" error, ensure you are running it through the Microsoft HTML Application host, not just a standard web browser. Troubleshooting Common Issues

Despite its age, SFM25 is surprisingly resilient, though modern Windows versions can be picky: Windows 10/11 Compatibility : If the compress/decompress feature fails, ensure the FFEDITC_UNICODE.EXE

utility is present in your MSTS Utils folder and that SFM is correctly pointed to it. Internet Explorer Dependencies

: Because it’s an HTA file, it historically relied on IE components. If the interface looks broken, check your Windows "Turn Windows features on or off" settings to ensure legacy script support is active. "Compress Failed" Error

: If you get an "Object Error" when closing, try refreshing the file display within the manager before attempting the operation again.

For more advanced needs, many players now use SFM in tandem with Open Rails

, which features a more robust file parser that can often ignore minor errors SFM might flag.

Shape File Manager v2.5 (SFM25) is a essential utility for Microsoft Train Simulator (MSTS) and Open Rails users, designed to modify (shape) and

(shape definition) files without needing complex 3D modeling software. Elvas Tower Core Capabilities SFM25 acts as a graphical interface for the FFEDITC_UNICODE.EXE utility. Key features include: Claranet Soho Compression/Uncompression : Converts binary files into editable text format and back. Scaling and Shifting

: Rotates objects 90 or 180 degrees (reversing) about the Y-axis. Visual Adjustments

: Modifies distance levels (LOD), MIP Map levels, and texture lighting modes (e.g., specular fixes for shiny locomotives). Elvas Tower Installation Guide

For SFM25 to work correctly, follow these steps to ensure all dependencies are met:

: Unzip the SFM25 files into a dedicated folder. A common location is within your MSTS Utils\FFEDIT directory or a standalone folder. Dependency FFEDITC_UNICODE.EXE from your MSTS Utils\FFEDIT

folder directly into the SFM25 folder. The program must find this file in its own directory to function. : Double-click to start the program. : Some antivirus software may flag files. This is a common false positive for this tool. Windows 10/11 Fix

: If the program fails to open or opens as a text file, ensure it is associated with Microsoft HTML Application Host ), typically located in C:\Windows\System32\ Elvas Tower Basic Usage Steps Select File : Open SFM25 and browse to the file you wish to modify. Uncompress

: Click "Uncompress." You cannot edit binary shape files until they are in text format. : Choose an option like "Scale" or "Shift." : Enter values for X, Y, and Z directions.

: Useful for rotating rolling stock that faces the wrong way. Save & Compress

: Once edits are complete, use the "Compress" option to return the file to its optimized binary state for the simulator. Elvas Tower Troubleshooting Common Issues "Not a valid Win32 application" : This usually happens if you try to run the

file directly with an incompatible program like Internet Explorer instead of the Windows HTML Host. Error on Compress/Decompress FFEDITC_UNICODE.EXE and its supporting files (like newshape.bnf ) are in the same folder as SFM25. Animation Issues

: For shapes with complex animations, ensure you have the updated newshape.bnf file, or the compression might fail. Elvas Tower using the shifting features in SFM25? Elvas Tower: Shape File Manager v2.5

6. Workflow Integration with Other Tools

For a complete MSTS content creation pipeline:

| Step | Tool | SFM Role | |------|------|----------| | 3D Modeling | GMax / Blender (with MSTS exporter) | N/A | | Initial Export | .S file (compressed) | Open in SFM → Decompress | | Hierarchy & Animation Tuning | SFM 2.5 | Verify part names, fix rotation | | Texture Mapping | TGATool2 / AceIt | SFM can rename texture paths | | Physics & Sounds | Eng/Wag editor | SFM bounding box affects coupler behavior | | Final Testing | MSTS / Open Rails | SFM fine-tunes lights & wheels |


What is Shape File Manager?

For the uninitiated, MSTS uses .s files (Shape files) to define the 3D geometry of everything you see in the simulation—trees, houses, stations, and terrain objects. These files are compiled and notoriously difficult to edit once created.

Enter Shape File Manager. Originally developed to manipulate these binary files, the tool allows users to decompress, analyze, and modify shapes without needing the original source 3D modeling files.

1. Introduction

MSTS shape files contain compressed 3D geometry, hierarchy data, and lighting parameters. Direct hex editing is impractical. SFM 2.5 decompiles, modifies, and recompiles these files, enabling developers to:


Typical workflow (step-by-step)

  1. Back up your route/asset folder.
  2. Open SFM25 and use File → Open to load a .S shape or package folder.
  3. Inspect the object tree: meshes, materials, and texture references.
  4. Extract textures to a working folder (right-click → Extract).
  5. Edit attributes: set correct scale, pivot/origin offsets, and LOD distances.
  6. Replace or edit textures in an image editor; re-import (right-click → Replace Texture).
  7. Fix material settings: enable two-sided faces, set glow/specular maps if needed.
  8. Use Export → OBJ to generate an OBJ + MTL for use in Blender or 3ds Max (check axis/origin conventions).
  9. Test in MSTS: copy modified shape and textures into the correct folder and load the route/scenario.
  10. Iterate: adjust normals, UVs, or LODs if rendering artifacts appear.

Key features

3.1 Initial Setup Work
