Inspect files down to the bones!

Discover the glTF format and find its full content stripped in a nice visual breakdown. Including every bit of a glTF’s asset structure, from nodes and samplers, over lights and cameras, to joints and animations.
Have a deep look into the details and inspect every single property glTF has to offer!
Thanks to multiple visualization modes and proper representation in UI and rendering, debugging your glTF has never been more convenient.

Edit all you want!

You are done editing text files? Start working in a fully visual interface!
Easily modify every property of each single glTF component with instant results. Tweak materials, change textures, adjust values or redo your scene completely. Gestaltor now empowers you to do everything you never dared!

Getting tons of export issues when converting assets into glTF? Fix them up with Gestaltor in a completely native environment!

Compose scenes inside glTF!

With Gestaltor, simple glTF files are not the end of the workflow pipeline anymore! You can now merge multiple glTFs into one scene and create new compositions, completely inside a glTF proven environment.
This even including setting up cameras and lighting.
This not only means importing content from several files, but also creating new glTF files from scratch by creating your node hierarchy and assets directly in Gestaltor.

Optimize content to your needs!

Fine tune files to your personal use case with the powerful editing tools of Gestaltor! Clean up files by deleting unnecessary nodes, duplicated textures or even by reducing/deflating some of them to a single value instead.
All of this can have a major impact on your loading and execution times.
Take control, build/forge a strategy and go for it! Gestaltor has your back and ensures to always export a valid, clean file without any unused data or legacy stuff.
Even ordinary restructuring and renaming will bring major benefits to your team’s workflow and can now be done more easily than ever!
