Morph target support

[lasalvavida]

1. Make/find & license a simple COLLADA model with morph targets

   • Preferably make a COLLADA model that is analogous to this simple glTF sample model: AnimatedMorphCube

2. Add conversion support for generating glTF morph targets

@sbtron does Microsoft have any simple COLLADA models with morph targets we could use? Or could a tech artist make one? 👍

I made a couple of very simple morph target scenes for Maya, with and without animation, with and without skinning, if these are of any help, I can export these to DAE if you want.

[lasalvavida]

That would be awesome and much appreciated @ziriax!

I have the source fbx used to generate the AnimatedMorphCube and AnimatedMorphSphere. Should be easy to put them into blender and get a COLLADA file out of them. Would that help?

Absolutely, more test models is always better.

Err, scratch that. We did the animation inside Unity, so it will not be super easy to get them into COLLADA unless we can export to COLLADA from Unity.

Yes you can. https://assetstore.unity.com/packages/3d/characters/collada-exporter-for-unity2017-99793 Regards -- Rémi

@lasalvavida I tried exporting the simplest scene I have from Maya to DAE (two quads, one with a blend-shape modifier, the other without), and that failed (when re-importing in Maya things are broken). So I'm afraid I won't be able to help that easily..

@soadzoor submitted a morph target test model to CesiumGS/gltf-pipeline#365.

animation_test.zip contains a .blend source file and exported .dae file, which looks correct.

@soadzoor would it be ok to use this model for testing here?

[soadzoor]

@lilleyse I guess/hope so. I'm not the one who created it. I believe it's part of the official glTF-Blender-Exporter - scene examples (01_morphed_cube.blend -> this is the one)

I only made some minor changes to the color values.

If you (or anyone) need a different model for testing, just tell me and I'll try my best. I've been learning blender for a couple of weeks now.

[lasalvavida]

@soadzoor, it looks like the attached exported COLLADA doesn't have animations. I'd like to use this to test #206 if there's any chance you could re-export it with the animations?

[soadzoor]

@lasalvavida Hmm.. I cannot find an option to export animations as well, when it comes to DAE.. Is it possible that blender doesn't support it? I tried to google for answers with no luck
