 +==== Distributing points ====
 +
 +When distributing points, it is important to understand that the **vertices** are the elements that are going to be used to calculate the texture so a high number of vertices is required on a grid for example to create the textures. 
 +
 +A **viewer node** can be used to visualize the pattern to align the number of points to a sufficient amount to properly see the patterns. 
 +
 +**Color ramps** may be used to further augment the contrast and distribute points finely on a given texture.

 +
 +To distribute points but avoid proximity to geometry use a setup including **Geometry Proximity** similar to this :

 +==== Instancing Collections ====

 Noodles with dotted lines are actually field values and can be thought of as lists or arrays in programming. They contain a value for a select number of items. Noodles with dotted lines are actually field values and can be thought of as lists or arrays in programming.
