Gestaltor is the first visual glTF editor to directly modify .gltf and .glb files. One of the main features of this 3D editor and stager is, that a glTF is loaded and saved. This means, that any information and configuration inside the glTF during editing is preserved.
glTF is the 3D format of choice for the Metaverse, Web3, 3D Commerce and simplifies the digital twin exchange. glTF 2.0 became an ISO standard in July 2022.
Following assets do help to create content using Gestaltor for the following open Metaverse platforms.
