Projects & File Types
Vertexix reads and writes three kinds of file: its own project and document files, 3D meshes, and images. This page lists what each one is and where it comes from.
Projects
File > Save Project... writes your whole working session to
a single .vxp file: the Loaded Mesh and the Generated Mesh, UV
spaces and bakes, the rig, strokes and a curated set of settings.
Open Project... reads one back. Save Project is available
once a mesh is loaded.
A .vxp also opens through drag-and-drop or the File menu’s
Recent list, which remembers recently opened files. Voxel
scenes keep their own list under Recent Voxel Scenes; picking
one switches to Voxel mode and loads it.
Other file types
| Extension | What it is | Where it comes from |
|---|---|---|
.vxp | Vertexix project | File > Save Project... |
.vxs | Vertexix sculpt | Save Sculpt... / Load Sculpt... in Sculpt mode |
.vxv | Voxel scene — the whole voxel tree, still editable | Voxel mode’s file buttons |
.vxo | Voxel object — one object, used like a preset in another scene | Voxel mode’s file buttons, acting on the selection |
.vxn | Node graph | File > Export Node Graph... / Import Node Graph..., and node presets |
.vbr | Brush settings sidecar saved beside a brush image | Written automatically for each brush in the library |
.vxbrush | Exported Vertexix brushes, one file to share | Export Brush... / Export Folder... in the brush list |
.vsb | Sculpt brush preset (settings only) | Saved sculpt brush presets |
.vsp | Surface preset | The Surface Presets window |
.sel | Saved selection, written beside the model file | Save Selection to Disk... / Load Selection from Disk... |
.seams | Marked seams on the Generated Mesh, written beside the model file | Save Seams / Load Seams in Seam Tools |
.ppp | PBR preset | Save PBR Preset... / Load PBR Preset... |
.hrz | Viewport background gradient look | Horizon Presets |
.mtlx | MaterialX (OpenPBR) material | Saving or loading a material as MaterialX |
.abr | Photoshop brushes | Brush import |
.gbr, .gih | GIMP brushes | Brush import |
.kpp, .bundle | Krita brushes | Brush import |
.myb | MyPaint brushes | Brush import |
The Vertexix document types (.vxp, .vxs,
.vxv, .vxo) open the same way as a mesh —
through drag-and-drop or Recent — and switch to the
matching mode.
Meshes
Mesh import is broad: FBX, glTF/GLB, OBJ, Collada, USD (.usd, .usda, .usdc, .usdz),
Alembic (.abc) and many more formats. A
.ply that contains only points is reconstructed into a surface
— see Point Cloud
Scans. What USD and Alembic files bring with them is on
USD and Alembic Files.
Meshes export as OBJ, PLY, FBX, GLB, glTF, Collada, STL, 3MF and USD, depending on your edition — see Formats & Edition Availability.
Images
Images can be saved as PNG, JPEG, BMP, WebP, JPEG XL, OpenEXR, Targa, IFF or TIFF. OpenEXR export needs Vertexix or Vertexix Ultra — see Editions Compared. JPEG XL is in every edition.
Material images can be opened from PNG, JPEG, BMP, Targa, GIF, HDR, PSD, WebP and JPEG XL files. A JPEG XL image with more than 8 bits per channel keeps its full depth, like a 16-bit PNG.
