.vta File Extension
Learn what a Valve VTA vertex-animation file contains, how to open it, and how Poly supports it.
File extension details for .vta
Partial Support| File type | Valve vertex animation |
|---|---|
| MIME type | |
| Encoding | Plain-text per-vertex animation samples |
| Operating systems | Windows, macOS, Linux |
| Opens with | Blender with a VTA importer, Crowbar |
| Poly support | Partial. Poly recognizes valid VTA data when its structure is supported. |
| Indexed by Poly | Yes. Poly indexes the filename and available scene metadata. |
| Preview in Poly | No standalone geometry preview. VTA animation needs its compatible mesh. |
| Poly agent | Partial. An optimized rendition is available when VTA contributes to a compatible scene; it is not a standalone object. |
What kind of file is a .vta?
VTA is Valve's text-based vertex-animation format. It stores per-vertex positions for animation frames and is applied to a matching mesh; it does not define a complete textured object by itself.1
How do I open a .vta?
Use Blender with a VTA importer or Crowbar, together with the matching Source mesh. Check vertex counts, frame timing, and animation bindings after import.
Poly support for .vta
Poly recognizes .vta under model/x-smd and indexes its filename and available metadata. Because VTA has no complete mesh, it has no standalone object preview. A compatible scene lets the animation contribute to agent understanding.
Working with .vta files
Keep the original and export through a Source-aware tool when moving to another scene format. Verify vertex ordering and animation timing after conversion.1
