Hi.
I've created a scene with a box and added an animation of opacity. Then i exported it to gltf. I checked exported an animation in the sandbox and there is no animation with opacity.
I checked a FBX file in the Unity and it works without any problems.
I atteched a project.

I do not think that opacity is something that gltf format can animate.
Pinging @bghgary for confirmation

Yes, I confirm. Animations in the glTF 2.0 core spec can only target TRS and weights. There is a PR and discussion about animating other properties here, but until that's ready it won't be possible to do in glTF.

If you are not attached to gltf you can use .babylon file format which supports that feature
