Gestaltor is a powerful tool for dealing with glTF files. In addition to being able to view and debug glTF files, GESTALTOR also enables you to edit or even create 3D scenes.
Details from the Gestaltor homepage:
Gestaltor provides you with a powerful interface to massively speed up your workflows. Unleash the true power of glTF in its native environment, true to all Khronos glTF standards. Directly view, inspect, edit, optimize and compose your glTFs exported from any content creation tool and gear them up for deployment in any engine or viewer.
Help us to develop the best tool for you and your glTF related needs! Now is your chance to mold the evolution of Gestaltor. Test our Beta version and give us feedback about our features and your experience with Gestaltor.
We go hands-on with this flexible tool in the video below ( or here on Odysee ). If you want to check out Gestaltor, there is a fully functioning non-commercial version available for download for Windows, Mac and Linux platforms.
EDIT — It seems between producing this video and publishing, the Community version was just removed! This is deeply unfortunate and hopefully it returns.
