Can't bake normal map! (Urgent!)

Support Materials and Textures

I’m trying to bake normal map (highpoly to lowpoly).

I made a test scene with a simple high poly and low poly cube, but after baking I didn’t see any details on the normal map, here is the screenshot:

However, after I reduced the size of the high poly cube so that only pieces with sculpting were outside the low poly cube it worked fine!

My question is: After sculpting, my model was slightly deformed. And when I am placing together the low poly and high poly models, the high poly model is slightly shifted outside of the low poly model. How can I get a normal map of the high poly model in this case (and not to get an empty normal map where the meshes intersect?)

I need to figure it out before Monday, so I would be very super for your help!

Intersection should not cause any problem.
To bake a high poly to a low poly mesh, your low poly needs a UV map and an image node in its material that you have to select.
In the bake settings, check “selected to active” and make sure your ray distance is not too small.
Then, select the high poly first, then the low poly and hit bake.

If you got all these things right and don’t get the expected result, provide a blend file so I can see what’s wrong.
