An LSPROJ file may also be a project created by Snap Lens Studio, a program used to create augmented reality (AR) lens effects for Snapchat. It contains a project, which includes a model and the resources, such as materials, meshes, and textures, that make up the model. LSPROJ files are used to add various AR effects, such as a dancing hot dog or floating rubber ducky.

More Information

LSPROJ files do not contain the actual resources for the model, instead they store paths to the resources, which are stored outside of the LSPROJ files. LSPROJ files are saved in JSON format.

You can open LSPROJ files in Snap Lens Studio by simply double-clicking the file. You can also open LSPROJ files in a text editor to view the properties of the project.
