Extract text from SPT files
To convert your SPT file to another format, you need SpeedTree Modeler or other 3D software.
To convert other file formats to the "Procedural Nature Asset" file type, you need software like SpeedTree Modeler or a similar tool.
The .SPT extension is a "polysemous" container, most prominently serving as a procedural vegetation file for IDV SpeedTree. These files contain mathematical definitions of trees and plants rather than static geometry, allowing for infinite variation and wind animation in blockbuster movies and game engines like Unity and Unreal Engine. The primary challenge with SpeedTree .SPT files is their proprietary nature; they cannot be directly imported into software like Blender or Maya without first being "baked" or exported into exchange formats.
However, .SPT is also a common extension for data and script files. It frequently appears as a compressed configuration backup for SpeedTouch routers (often GZIP compressed), a scenario script for the Kirikiri visual novel engine, or a molecular visualization script for RasMol. Because of this overlap, users often face "unknown file format" errors when attempting to open a text-based script in a 3D viewer, or vice versa.
For 3D workflows, the ideal solution is converting the procedural definition into a static mesh like OBJ, FBX, or USD for universal compatibility. For script and configuration files, converting or renaming to TXT allows for immediate inspection in standard text editors.
Convert.Guru analyzes your SPT file, detects the exact format, and lets you read the text inside.
Users also converted STP, SPTX, MP4, SKP, XPT, ZIP, RPM, SIT, CBR, CPT and CU files.
If you want to convert SPT file to CBR, CPT, CU, DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP or IGES, you can use SpeedTree Modeler or similar software from the "SpeedTree Procedural Model" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to SPT, try SpeedTree Modeler or another comparable tool in the "SpeedTree Procedural Model" category.
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 SPT converter.
