Modeling bumpy polygon plane

This simply Python script creates bumpy surface on a polygon plane by altering the Y position of each vertex points in a random manner. The User Presets area can be edited according to your needs.

import maya.cmds as cmds

import random

#User Presets Below This Line-----------------

numberOfVertex = 10200 # Number of vertexes

pName = 'pPlane1' # Name of polygon plane

loR = -5 # Lowest point of bumping

hiR = 5 # Highest point of bumping

mult = 0.1 # Magnitude of randomness

#User Presets Above This Line-----------------

for i in range(1,numberOfVertex):

    vtx = ('%s.vtx[%s]'%(pName,i))

    cmds.move(0,(random.randrange(loR,hiR)*mult),0,vtx,r=True,ws=True)

Note that if your polygon plane is very high in resolution, it might take longer to complete depending on the processing power of your machine. I tried 10000+ vertexes and it took my computer's Maya about 30 seconds to complete.

Don't panic if Maya froze during the process!
