I am now using Blender 2.8 and create my own model, I add a new material and
link an image texture node to its color channel. However, when I try to export it to a collada file, and reimport it, the image texture disappear! It works only if I use Principled BSDF shader, it fails when I use other shader types such as Emission shader.
the selected object is the reimport mesh, the image texture is preserved in this case.
again, the selected object is the reimport mesh, the image texture is missing in this case.
So what is the proper way to export materials to collada file, or is it possible to export image textures correctly?
