Normal map issues

[serenios]

Hi, recently I'm using your code to render normal maps.
But I find that the rendered normal map looks like different to the traditional one.

It looks like

rather than

So, I wonder if there could be a way to render normal maps looks like the above one.
Thx!

Do you mean a bump map?

The normal map created here does the "normal" thing by visualizing the normal vector (ie the vector pointing away from the surface) to RGB.

Thanks very much for your reply!
Actually I mean normal map in Tangent Space.
The predominantly blue looking normal maps.
Which looks like this, for example:

if there could be a way to render this kind normal maps.

I see. It should be possible to add a Normal Map Node and set the space there to tangent, see https://docs.blender.org/manual/ko/dev/render/cycles/nodes/types/vector/normal_map.html.

The script currently does not use a Normal Map Node, it simply reads out the normal from the render layers that are always present, see

stanford-shapenet-renderer/render_blender.py

Line 73 in f77a793

links.new(render_layers.outputs['Normal'], scale_normal.inputs[1])

I'm happy to accept a CL that adds an option for rendering tangents!
