Postshot

Postshot, a pioneering German radiance field company, has been making waves since its Beta launch on December 20th, 2023. For those unfamiliar, radiance field technology is at the forefront of creating hyperrealistic 3D environments, and Postshot has quickly emerged as a leading platform. Its approach ensures that all data is processed locally, providing data security by ensuring it never leaves your computer.

Exclusively available for Windows users, Postshot simplifies access with a one click download system and offers an intuitive selection of settings for user friendly interaction with digital scenes. It is easily the most approachable for non technical users of all the locally training radiance field platforms. Although currently limited to Windows, potential expansion to other operating systems could broaden its accessibility in the future. A NVIDIA GPU is necessary to run Postshot.

Previously they offered both proprietary implementations of NeRFs and Gaussian Splatting. However, as of today, only gaussian splatting is continued to be supported.

For nearly the first two years of its existence Postshot was free to use. Jawset now sells three tiers. The free tier allows unlimited image count, video length and model size, trains and renders up to 4K in 8 bit color, and exports camera poses and points, but it is non commercial, watermarks rendered output, and locks saved project files to the free plan. Indie costs 17 euros a month or 204 euros billed yearly and adds commercial use, watermark free rendering, a floating license usable on any device, unlimited render nodes, and radiance field export in PLY and SPZ. Studio costs 39 euros a month or 468 euros billed yearly and adds EXR, TIF, DNG and RAW input, training and rendering above 4K and in 16 or 32 bit HDR color, the command line interface, automatic scene alignment from AprilTags, and camera and point import in BlocksExchange and Pix4D OPF formats.

Radiance field export covers PLY and SPZ, and Postshot 1.1.43 writes SPZ version 4. The same release adds a quality option for SPZ exports and an option to limit the spherical harmonic degree at export time, so the harmonic budget can be capped when writing a file rather than only when configuring training through Max Sph. Hrm. Degree. Degrees 1, 2 and 3 require 64, 171 and 321 percent more data than degree 0. Postshot 1.1.43 also adds an HTML export target, and Jawset does not document what that target contains or which subscription tier it belongs to.

Since Postshot's original release, they have expanded their offering to also include 3DGS MCMC and the Splat3 profile. Additionally, Postshot has taken steps to give users more control over parameters, such as specifying how many images frames they would like to use, the max splat count, and how many steps should the model be trained to.

Postshot ships plugins for Unreal Engine and After Effects. A .PSHT project file dropped into the Unreal Content Browser becomes a PostshotProjectAsset, which becomes a RdncFieldActor when dragged into the level, and a packaged Unreal project still requires the Postshot app to be installed on the target machine. Jawset's user guide documents plugin support for Unreal Engine 5.4 through 5.7 and has not been updated for 5.8, which Postshot 1.1.43 adds. Postshot has been used in several media campaigns, including Usher’s recent music video for “Ruin”.

Postshot is available to download from Jawset.com and is currently only available on Windows. For any feedback, please send your questions and feedback via Discord or email to support@jawset.com. Postshot is unfortunately not available for Mac.
