Normal Map

Normal maps are used to fake high-res geometry detail when it's mapped onto a low-poly mesh.

Today we created a normal map for a detailed plane that was fused with booleans, extruded polys and floating geometry.



Hi-res geometry



After creating a new plane, tweaking the render setting and adding a Projection Planar Map to the new plane, I got a bump map:


 
Then all you need to do is apply the bump map as a Normal Bump material to the new plane:



It looks 3D!
