What it does

Resource Explorer gives track creators and modders a practical way to examine game data. Open a supported resource, see what is inside, and choose the next step from one Windows application.

01 / BROWSE

Open and understand archives

View entry names, detected file types, sizes, and offsets. Search filenames or scan archive contents for text without extracting everything first.

02 / PREVIEW

Inspect files in context

Preview supported images, text, metadata, and models right from an archive. Switch to hexadecimal data when you need to inspect bytes directly.

03 / EXTRACT

Work with the assets

Extract individual entries or a whole resource. Supported terrain files can produce OBJ meshes, heightmaps, textures, and related track information.

04 / EDIT

Rebuild supported resources

Edit archive contents by adding or replacing files, then save or rebuild from an extracted working folder. Rebuild manifests keep track of archive entries.

05 / VIEW

Explore terrain and models

Use the built-in terrain viewer to rotate a mesh and inspect elevation or spline overlays. Supported SLT objects can be examined in the preview pane.

06 / VERIFY

Check your work

Run structural verification on supported archives and compare a working folder with its rebuild manifest before creating an updated resource.

Files and formats

Support depends on the game and resource type. The Explorer focuses on making available data accessible, while unknown entries remain extractable for separate investigation.
