-
model_orig.glb is the model before quantize, which is ok
-
model_gltf-transform.glb is the model quantized with steps below, which can reproduce this issue.
-
model_gltfpack.glb is the model quantized with gltfpack -ke -kn -km using gltfpack 0.18, which is ok
Actual behavior:
Load model_gltf-transform.glb in and drag around:
To Reproduce
Steps to reproduce the behavior:
- Go to https://gltf.report/ and drag in
model_orig.glb
- Click on Script button
- Use code below to do a quantize
import { quantize } from '@gltf-transform/functions';
await document.transform(
quantize()
);
- Run and export
- Open https://playground.babylonjs.com/#N036XF and load the exported model in the right panel.
Extra Info:
This issue is also reported to glTF-Transform:
Another thing to notice is that gltfpack uses u16 for position and gltf-transform uses i16_norm for position, this could make a difference.
