This article explains the settings and values for the Corona Normal shader in Cinema 4D.
Overview
The Corona Normal is a shader that can be used to load Normal maps that can provide additional fine details to the material surface.
This shader is supposed to be inserted under the bump channel of Corona Material.
Channels direction
Texture – This slot defines the texture map or shader that will be used to calculate the Normal bump.
Texture loaded as Normal shader must be loaded with linear color profile.
Method – These are the different methods to calculate the Normal bump.
Override UVW – This option allows you to use a different UVW channel for the Normal bump.
Flip X (red) – When enabled, this checkbox inverts the side for the X axis for the Normal bump.
Flip Y (green) – When enabled, this checkbox inverts the side for the Y axis for the Normal bump.
Flip Z (blue) – When enabled, this checkbox inverts the side for the Z axis for the Normal bump.
Swap red & green – When enabled, this checkbox swaps the X and Y axis for the Normal bump
Additional bump mapping
Strength – This is the intensity (also considered as the visibility) for the additional bump texture.
Texture – This slot defines the texture map or shader that is used for the additional bump.
A grayscale or black & white texture map (or shader) must be used for the additional bump.
