Animation Support in GLTF file

Hi there,
I just wanted to add the animation in the GLTF model exported using c#.
Is there any API or solution by which I will add it.

Are you hoping to use C# to apply animation? Or just any software? I would probably look at these options if you need a C# SDK:

But I’m not a C# programmer and can’t guide you much more than that.

I would note that for complex animations, most people prefer to use artist-friendly tools like Blender or 3DS Max.
