How to add prefix to baseColor_xx.jpg?

[ringcrl]

After using the write method, there will be three files exported: baseColor.jpg, modelName.bin, and modelName.gltf. However, all my resources are stored in one directory. Different models will use the same baseColor.jpg file, but they actually have different contents, which may cause them to overwrite each other. I haven't found a place where I can configure the name "baseColor". Please let me know how can I make the exported texture image in the form of modelName.baseColor.jpg, thank

Hi @ringcrl! It sounds like you are using the scripting API and NodeIO to read/write? If that's not the case and you're using the CLI instead, I think you'll need to use the scripting API. The names of textures are configured by the Texture#setURI method; if unspecified, defaults are chosen.

For example:

import { ImageUtils } from '@gltf-transform/core';
import { listTextureSlots } from '@gltf-transform/functions';

const io = new NodeIO();
const document = await io.read('path/to/modelName.glb');
const prefix = 'modelName';

for (const texture of document.getRoot().listTextures()) {
  const slot = listTextureSlots(texture)[0] || 'unused';
  const extension = ImageUtils.mimeTypeToExtension(texture.getMimeType());
  texture.setURI(`${myPrefix}.${slot}.${extension}`);
}

await io.write('path/to/modelName.gltf', document);

If you prefer to put images into folders, you can also prefix the path with the name of a folder.
