About VSO files

A .vso file is most commonly a Compiled Vertex Shader Object, a binary format used in 3D graphics rendering. These files are the compiled output of High-Level Shading Language (HLSL) source code, processed by the Microsoft DirectX SDK or game engines like Valve Source and Unity. They contain low-level instructions that tell the Graphics Processing Unit (GPU) how to manipulate vertex data (geometry positions) in 3D space.

A significant minority of these files are Vectorworks Script Objects generated by Vectorworks, a BIM and CAD software suite. These contain compiled scripts or plug-ins used to automate tasks or define custom object behaviors within a design project.

Common Friction Points:
Since shader .vso files are compiled binaries, they are not human-readable. You cannot simply open them in a text editor to change the graphics code. They are often optimized for specific GPU architectures or driver versions, making them fragile to move between systems. If you have lost the original source file (usually HLSL, FX, or VSH), modifying the shader is extremely difficult without decompilation tools. Similarly, Vectorworks objects are proprietary; if you don't have the specific version of Vectorworks installed, the data is essentially locked away.

Best Conversion Targets:

For Shaders (Reverse Engineering): The primary goal is to convert the binary back to Text or HLSL source code using a shader decompiler/disassembler for analysis.
For Vectorworks: These must be opened in Vectorworks and can generally be exported to DXF, DWG, or PDF for sharing, though the script logic itself usually stays internal.

Convert.Guru analyzes your VSO file, detects the exact format, and lets you read the text inside.

Users also converted DDS, FX and X files.

The VSO Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our VSO converter.
