How to export Cycles Baked Textures into a Collada file

I’m trying to export a model with Cycles baked UV textures but the textures are not exported into the Collada ( .dae ) file.

Does someone know how this is done or how it should be done?
Could you give a working example, please?

Because I’m a new user, I can’t upload the blender file. Please let me know if you need it and I can send it to you. Thanks a lot and hope to hear from you soon

I don´t think you can save textures into a collada file.
Usually when exporting to a format like cda or fbx only things like geometry, material IDs, normals and similar things are saved into the file.
The textures are only referenced as file paths either absolute like this for example:
or relative like this for example:

The program you import it into later has to either find the textures with this information and reassign them or you have to do it manually there.

.glb has a way of getting the textures into the 3d file. Collada support in blender is incomplete. You have to save your baked texture to file.

Thanks for the insight and help! Thanks a lot!
