Hello dear Blender community,
I'm working since a few days a good way to create heightmaps from meshes. Everything works fine, but when rendering (eevee) the colors are always wrong. White should be black and vice versa. If I now add an invert node in the compositing tab, the image is totally blended and you can no longer see any structures.
Picture 1: Without invert node, you can clearly see the buildings.
Picture 2: With invert node, hardly anything can be seen of the buildings.
What am I doing wrong? Shouldn't it actually be totally simple?
