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:
- GitHub - vpenades/SharpGLTF: glTF reader and writer for .NET Standard
- GitHub - jkuhlmann/cgltf: Single-file glTF 2.0 loader and writer written in C99
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.
