glb model texture uv-mapping issue

[Nwjwifh]

Hello, I tried to uv-map png image on several glb models and change texture, but it doesn't work(picture 1).
Actually, I think color of image is applied, but I want complete image file wrapped on model(like picture2). Please help me

It looks like the UV coordinates (or texture transform) of the model is set to only use a small corner of the texture. You'll need to check in proper 3D authoring software like Blender.

Thanks for the answer. But is there any way of fixing this problem by editing gltf's json code?(without using software program)

You can probably fix it with a texture transform.
