I read the answer on the link on how to add transparent images on top of materials (Add a transparent image on top of a material ). This works beautifully in v2.79b.
This technique does not seem to work in Blender 2.80 anymore (I am using the very latest Mac version from Dec 20). The transparent image is also shown on the part of the mesh, which is not UV unwrapped. Is this a bug in v2.80? Or does v2.80 require a different approach?
What is really odd is the fact, that if I open in v2.80 a file created in v2.79 created, it shows up correctly.
Thanks for any advice! Chris
