Gltf loader png load

The file format is as follows.
The gltf loader loads the png file at the same time.
Because the pngs are in a continuous format, I want to load them one by one.
What should I do?

Can you elaborate on what you mean by this?

Are these different levels of detail of the same image? If so, your best option may be to split each level of detail into a separate glTF file.

The pngs are in numerical order, and if you show them in order, they make it look like a moving image. Therefore, I want to make it look like a moving image by showing it one by one in order.

Texture animation like GIF

Is there any other way to split the gltf?

How are you creating the glTF? If it’s in Blender, you can select which objects to export and export only those in each file.

But I don’t think this is what you want if your goal is animation. You might try the solutions discussed here: GIF as animated texture? - #2 by Mugen87

Alternatively, if your meshes are given names, you could just hide all but the one “current” mesh, and every frame you do the same, showing the next mesh that should be displayed. This is assuming your glTF file contains one primitive/mesh per texture that you’re displaying.
