Highlights missing in "Full Render" bake

Hello everyone,

beeing new to Blender I can honestly say … I am loving it :wink:
But I still got some little problems with the “how” this software works.

At the moment I am struggling with baking maps. In the attached image you can see the rendered result on the right and the “full render” bake on the left side. What I am missing are the highlights on the edge of the couch. The UV faces should be in the red circle, but there is no highlight information baked.

Did I make something wrong ?


It would be great if someone could help me with my problem

Cheers
