A question about using a morpher in 3dmax and loading glb files in ThreeJS. #1108

Closed baipiaoguaiisme closed 5 months ago

When I use BabylonJS in 3dmax modeling software to export a mesh with a morpher as a glb file, and load the glb file in ThreeJS, I find that the vertex position data of the first morph target and the second morph target are the same, which means that the data of the first morph target overwrites the data of the second morph target. Or the data of the second morph target overwrites the data of the first morph target,for example, when there are four different morph targets, the first and the second morph targets are the same, and the fourth morph target disappears!So the fourth morph target animation doesn't show up. Seems like it's BabylonJS's problem and not ThreeJS's problem?

Can you provide a repro scene?

Can you download this zip file? The zip file contains the relevant code and models. Instructions are in the README file. scene.zip

@SergioRZMasson Can you investigate when you get the chance?

@baipiaoguaiisme This was fixed in the latest version of the exporters. If you use the latest version it should work fine.
