What is a .SPP file?
SPP is a project from Adobe Substance 3D Painter, used to texture 3D models. Created and opened by Substance Painter.
- Did you know
- Substance Painter came from Allegorithmic, which Adobe acquired in 2019.
- Substance Painter lets artists paint textures directly onto a 3D model following a physically based rendering workflow.
- Since version 8.2 the application stores its own version number inside each saved SPP project file.
- What Analyser reads
- Identify design-app files: Figma (FIG), Affinity Photo/Designer/Publisher, CorelDRAW (CDR), MediBang Paint (MDP) and Substance. A Figma file has its container read out - format, Kiwi version and chunk sizes - but not its contents: Figma encodes the design with Kiwi, a schema-driven binary format whose schema ships inside the file and changes with the version of Figma that wrote it, so there is no stable structure to walk. Sketch, by contrast, opens in a full viewer - see Sketch above. GIMP (XCF) does too, and Krita (KRA), Procreate and Paint.NET (PDN) show their embedded preview - see Raster art above.
- Depth of analysis
- .SPP is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .SPP file
- Drag a .SPP file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
