Postshot for Gaussian Splatting: A Quick-Start Guide
Tutorial · 2026-06-04 · 6 min read · by SplatMart Team
Postshot is a fast desktop app for training Gaussian splats and NeRFs on your own machine. Here's what it does, who it's for, and how a basic workflow looks.
Postshot is a desktop application for training Gaussian splats (and NeRFs) on your own computer. Instead of uploading footage to a cloud service, you drop in your photos or video and Postshot processes the splat locally on your GPU, which gives you speed, privacy, and more control over the result. It's become a popular choice for creators who want to move beyond beginner cloud apps.
What is Postshot?
Postshot takes a set of images or a video of a scene and reconstructs it into a Gaussian splat you can preview, refine, and export. Because it runs on your machine, processing speed depends on your GPU rather than a server queue, and your footage never leaves your computer.
Who is Postshot for?
- Creators who make splats often and want faster, local processing.
- Anyone who prefers keeping footage private rather than uploading to the cloud.
- Users who want more control over training settings and quality than a one-tap app offers.
If you're brand new to splatting, a cloud generator is a gentler start. Postshot is the natural next step once you want more local control. New to the concept entirely? Start with what Gaussian splatting is, or compare Postshot with SplatMart's cloud workflow.
What you need
- Windows 10 or later with an NVIDIA GPU at compute capability 7.5 or above (Jawset currently lists an RTX 2060 or Quadro T400/RTX 4000 as the entry point).
- A good capture, overlapping photos or a slow, steady video covering the subject from many angles.
- The Postshot app installed.
A basic Postshot workflow
1. Capture
Film or photograph your subject with full coverage and even lighting, the same way you would for any splat, slow movement, lots of overlap, nothing moving in the scene. See our capture guide for technique.
2. Import and train
Create a project, import your images or video, and start training. Postshot solves the camera positions and optimises the Gaussians, showing you progress as it goes. Local GPU processing means you're not waiting in a cloud queue.
3. Review and refine
Inspect the splat for floaters and weak areas. You can adjust settings and retrain, or crop the scene to clean up the bounds.
4. Export
On a paid plan, export the trained Radiance Field as PLY or SPZ so you can view it, bring it into another tool, or share it. Postshot's free non-commercial plan does not include those Radiance Field exports. For the differences between splat formats, see the file-formats guide.
Postshot vs cloud apps
- Postshot, local, fast on a good GPU, private, more control; needs capable hardware.
- SplatMart Leighton, cloud-based, works from a browser, accepts up to 3,000 photos or sampled video frames, and charges per generation rather than by subscription.
- Luma AI / Polycam / KIRI Engine, cloud-based, beginner-friendly, and capture-oriented; feature and export terms vary by plan.
Whichever tool you use, capturing a polished splat takes practice. If you need a finished asset now, SplatMart sells ready-to-use splats you can download and drop into your project.
Frequently asked questions
What is Postshot used for?
Postshot is a desktop app for training Gaussian splats and NeRFs locally on your own GPU, from photos or video. It's used by creators who want faster, private, more controllable splat processing than cloud apps offer.
Is Postshot free?
Postshot has a free plan for non-commercial use. Its paid plans add commercial use and Radiance Field export to PLY and SPZ, among other production features. Check Jawset's pricing page for current plan pricing.
Do I need a powerful GPU for Postshot?
Yes. Postshot currently requires a compatible NVIDIA GPU because all reconstruction runs locally. Jawset lists compute capability 7.5 or higher, starting around an RTX 2060 or Quadro T400/RTX 4000. Cloud generators are the alternative if you do not own one.
What can Postshot export?
Paid Postshot plans export Radiance Fields as PLY and SPZ for third-party viewers and production tools. The free non-commercial plan can export camera poses and points but does not include PLY/SPZ Radiance Field export.
