From left to right : original material without normal shader, bump map image, material with the bump map shader

Warning

The bump map shader in Ocean 2016 was renamed to Height map shader. This shader is a new one, more coherent with traditional bump mapping.

Please keep in mind that only the normals are affected, but the surface is not actually displaced. This leads to physical inconsistencies if the shaded normal is very different from the geometric normal, for instance the angle of incidence may be greater than 90°. Therefore, this should be used for small distortion angles only.

multiplier

real

The amount of bump mapping

uvscale

real
