Legacy Noises are duplicates of noises & procedurals that ship with MARI but have been modified or

extended in MARI Extension Pack 3 R2 .

The following Noises exist as Legacy Versions:

• Legacy Cloud
• Legacy Squiggle
• Legacy Turbulence

• Found under:  

• Add Procedural Layer / Procedural / Custom / Noise /

• NodeGraph / Right Mouse Click / Add Nodes / Procedural / Custom / Noise /

---

• Legacy Perlin

• Found under:  

• Add Procedural Layer / Procedural / Custom / Perlin /

• NodeGraph / Right Mouse Click / Add Nodes / Procedural / Custom / Perlin

---

• Legacy Cellular

• Found under:  

• Add Procedural Layer / Procedural / Custom / Voronoi /

• NodeGraph / Right Mouse Click / Add Nodes / Procedural / Custom / Voronoi

The following features have been added to all Noises listed above:

• Clamp Output

Clamps the noise calculation to a 0-1 range.

Color A/B are applied after the Clamping, so you can still set values above 1 if you choose to

however by clamping the Noise calculation the color mixing between the two colors works more

reliably. In general this should be left on.

• UV Space

By default these procedurals are generated in 3D World Space. This results in a seamless noise across UV seams.

By turning on UV Space the procedurals are generated based on UVs, resulting in seams between UV tiles/UDIM & shells.

Utilizing Transform Controls such as Scale (see below) you can apply a non-uniform transform to the procedural

to make use of specific UV layouts.

• Scale X / Y / Z

Will apply a scale along X,Y or Z to your noise. This is useful for creating patterns like woodgrain, drips etc.

When UV Space is turned on Scale Z is ignored.

• Rotate X / Y / Z

Will apply a rotation in X,Y or Z to your noise. When UV Space is turned on Rotate X & Rotate Y are ignored

and rotation is done around the center of each UV Tile/UDIM using Rotate Z.

• Translate X / Y / Z

Will apply an offset in X,Y or Z to your noise. When UV Space is turned on Translate Z is ignored.
