GLTF Export Issues
« on: March 22, 2021, 21:14 »
Hello!

I have been using this software for a while now and I absolutely love it. Keep up the great work Gildor, thank you!

We have recently used UE Viewer to export Skeletal Meshes and Static Meshes from an Unreal Engine 3 game called Gigantic. However, the GLTF's have numerous issues according to the Kronos GLTF 2.0 validator. We are curious if this is a result of UE Viewer's GLTF exporter or something with the models inside of the game.

Thanks!

Hi,
These are not true issues, validator is piece of ... I did talk with its author, he's very refractory. When float 2.0 is printed by JavaScript as 2.000000001, he wants the same number to be stored in json text.
Actually this was mentioned somewhere else on this forum.

Thank you for the fast reply! From what I gathered they did not appear to be real issues and I would have ignored them, however, when trying to import the GLTF exported by UE Viewer into Godot engine, it was causing the engine to crash.

I recently put the GLTF's into https://github.com/zeux/meshoptimizer this program and they pass the validator and do not crash Godot anymore.

I did try loading glTF into 3 or 4 major JS frameworks. Fixed some issues not a long time ago (probably in February or March). All issues which I can see now are "array bounds in binary data doesn't match specified in glTF text" (I don't remember the message itself), or "data out of bounds" (when 2.000001 is larger than 2.0).

If you could provide me uasset files with meshes, then I'd be able to check if there's any "true" validator issue there, and fix the problem.
