I'm a student and this is my first experience with blender so I'm not an expert. I'm facing a problem when I try to bake normals in tangent space.
I have two meshes representing an Hippo, created following some tutorials on youtube. One is high poly, second is low poly.
I'm using blender render, as in the tutorials.
I'm able to create an uv map unwrapping the low poly mesh and to do the first bake (select low poly mesh and click bake in render menu).
It is one day that I'm trying the final step of the tutorial in which I open my uv map in the uv editor, select in bake options "selection to active", I select the high poly mesh, shif+select low poly mesh and I click bake again. I can see that blender do the bake but the result does not change in any way.
I found the tutorials on youtube typing "Hippo Blender". They are five and I followed everything. But between the video 4 and video 5, I put bones and two animation on my model (not done in the original tutorial). Then I started again with the last tutorial.
I'm using blender 2.79b in the tutorial it is used blender 2.6 I think. I try to read all the related topics in this forum but I'm not able to find a solution.
If someone can help me I can share the blender project
Thank you in advance
I edit the question after the answers adding some images of the current settings and the normals that I can see.
