Jawset's beta version of its radiance field platform, Postshot, is receiving a significant update.

This update introduces several enhancements, notably an improvement in display fidelity, which seems to be handling backgrounds well. Other notable enhancements include a refined crop box editor for the x, y, and z axis, complemented by advanced scene transform editing capabilities such as rotation and local translation.

A major feature addition is the capability to visualize and edit directly within After Effects, streamlining the workflow for users. Furthermore, Jawset has updated their capturing guidelines to help people create the highest fidelity captures possible.

The creative potential of Postshot was showcased in Usher's music video for "Ruin," which utilized Postshot's Gaussian Splatting feature.

It's important to note that Postshot's radiance field methods, including Gaussian Splatting and NeRFs, are proprietary implementations.

Full Changelog Highlights:

After Effects

  • Added Scene Transform parameter

  • Added Crop Box parameter

  • Fixed occasional incomplete/flickering renders

  • Fixed an unnecessary error message during startup

  • Effect was not re-rendered after loading a scene

Editing

  • Support rotate/scale/translate tools on radiance fields to edit scene transform

  • Added Crop Box child to radiance field nodes to focus rotate/scale/translate tools

  • Crop Box was not applied to Splat model

User Guide

Import

  • Support importing multiple image folders as one training set

  • EXIF metadata was not converted correctly, leading to tracking quality loss in some cases

  • Fixed a bug in image pre-processing that lead to loss in Splat training quality in some cases

  • Reduced peak memory usage when pre-processing images, preventing stalls on large image sets/long movies in some cases

  • Import of COLMAP databases did not use the correct sub-model of multi-model reconstructions

  • Fixed crash when trying to track images with different dimensions

  • Some PLY splat files were not imported correctly

Export

  • PLY splat exports did not load correctly in some Unreal Engine plugins

Camera Navigation

  • Hide&lock mouse cursor when dragging viewport camera

  • Added Unreal Engine-style dolly/pan controls (RMB + drag in ego mode)

  • Added Camera Move Speed parameter (below /Scene) to control speed of WASD viewport controls

  • Added camera move up/down actions with default shortcuts Q and C

GUI

  • Display number of splats in Radiance Field parameters

  • Reduced recommended maximum number of images to 400 to avoid unintentionally running long tracking jobs

  • Display additional information in ImageSet parameters

  • Display App version used to track, train and modify a file for better file version management

  • Show App version in Log view after startup

  • Added Open Log Folder shortcut button in Log tab

  • Paste-from-clipboard did not handle non-ascii characters correctly (e.g. in login dialog)

  • Fixed frozen UI when pausing tracking

  • Fixed frozen UI when restoring minimized window

  • Start-train button remained checked even after aborting via confirmation dialog

  • Model profile was not reset after rejecting re-training

  • Docks were not restored when UI state was not stored correctly

Installer

  • Auto-install app updates (io. only downloading) when confirmed by user

  • Added desktop notification for app updates

Jawset continues to make Postshot more accessible, emphasizing its user-friendly UI and UX among modern applications. Postshot can be downloaded as an executable for Windows here. Follow Jawset on Twitter or their Discord channel.
