MSTS Shape File Manager (SFM) 2.5 is a Windows utility for Microsoft Train Simulator (MSTS) that helps modders view, extract, edit, and manage shape (.S) files and related asset packages used by MSTS. It is aimed at route and scenario creators who need a convenient way to inspect geometry, textures, and metadata stored within MSTS shape and package files.
Model Scaling: Resize 3D models uniformly or independently along the X, Y, or Z axes. msts shape file manager 2.5
The "FF.exe" Requirement: For SFM to compress and uncompress files, it needs the ff.exe utility (found in the MSTS/Utils folder). Ensure SFM knows where this file is located during the initial setup. Common Workflows Fixing a Texture Error If MSTS crashes because it can't find a specific .ace file: Open SFM 2.5 and navigate to the broken shape file. Click Uncompress. MSTS Shape File Manager 2
Windows 11 Compatibility: Some users report issues with the compress/decompress feature on Windows 11. If it fails, tools like Zipper can be used as a standalone uncompressor before using SFM for editing. Archibald (by Piotr): A command-line tool for scripting
LOD & Texture Management: Adjusts Level of Detail (LOD) distance levels and MIP Map levels, and modifies texture lighting modes (e.g., specular fixes for shiny locomotives) .
At its core, Shape File Manager is a utility designed to manipulate the .s (Shape) files and associated textures used by MSTS. It was developed to solve a major headache for modders: MSTS shapes are often "locked" or difficult to edit without the original source files.
