So I have a sculpted model of a cat enter image description here

And a retop-version of it enter image description here

And now I want to bake the normal map from the first onto the second model, but 3 Youtube videos later it doesnt work, I mostly get an empty normal map(probably because I have no idea what I am doing)

What are the steps to bake stuff from a sculpted onto a retopologized model?

Low poly model.

enter image description here

High poly model.

enter image description here

Make sure both objects are in the same location. Select the low poly object and create a material. Create an Image Texture node and Normal Map node. Plug the colour from the texture node to the normal map node. Plug the normal into any shader, in this case it's the default Principled BSDF. Use the image texture node to create a new image of any size. Set the texture node Colour Space to Non-Colour.

enter image description here

Now select both objects, having the low poly object with the material attached as the main selection.

enter image description here

Go to the Render Properties panel > Bake. Change Bake Type to Normal. Check the Selected to Active option. The Extrusion slider will need to be adjusted depended the scale of your object. Click Bake.
