The Surface menu contains controls to apply noise to the mesh. Noise is a render effect – it does not affect the geometry of the mesh and so is not dependent on the number of polygons. However, noise can be applied to the mesh so that the geometry is displaced, in which case sufficient polygon detail will be needed to capture the detail.
Tool > Surface sub-palette
Noise
The Noise button turns noise on and off for the selected mesh. If no noise has been applied then the NoiseMaker pop-up interface will be launched.
Edit
Launch the Noise pop-up interface so that the current noise settings can be edited.
Del
Delete the current noise settings. All noise will be cleared and the Edit button disabled.
Apply To Mesh
The Apply To Mesh button will apply the noise to the mesh.
If either Color0 or Color1 is on the RGB will also be applied to the mesh. (Remember noise does not depend on polygons. When appling noise to a mesh you will need to divide the mesh up to capture the RGB and Noise.)
SNorm
The SNorm slider will smooth the normals of the mesh before Apply To Mesh is pressed. This will help avoid overlapping polygons when the noise is applied.
NoiseMaker
NoiseMaker interface
Open
Open a NoiseMaker file.
Save
Save a NoiseMaker file.
Copy
Copy the current NoiseMaker settings so that you can apply them to a different mesh.
Paste
Paste NoiseMaker settings from a different mesh.
2D
Apply noise is two dimensions (color intensity only).
3D
Apply noise in three dimensions.
Uv
Apply noise based on the mesh UVs.
Scale
The Scale button will increase the size of the noise. A larger setting will create larger peaks and deaper valleys.
Strength
The Strength slider will control how extreme noise will be applied to the mesh.
ColorBlend
The Color Blend slider adjusts the intensity of Color0 and Color1.
At 0 there will be no color applied to the cavity of the noise. When the slider is moved from 0 to 1 it will effect the intensity of Color1. When the slider is moved from 0 to -1 it will effect the intensity of Color0.
Col1 and Col2
Noise curve
The Noise Curve alters the intensity of the noise, from the values originally defined. Moving the points of the curve upward intentifies the peaks of the noise, and moving points of the curve downward intentifies the valleys of the noise.
