TwoThings Every Technical Artist Has to Know

TwoThings Every Technical Artist Has to Know
In this tutorial, we will cover three crucial skills that every technical artist must master:
1. Using Python for Selections: Learn how to efficiently pick and manage selections within your favorite 3D software.
2. Setting Parameters, Attributes, and Knobs: Discover how to automate and customize parameters (Houdini), attributes (Maya), and knobs (Nuke) to streamline your workflow.
Whether you're a beginner or looking to deepen your expertise, this tutorial is designed to provide you with practical skills and insights that you can immediately apply to your work. Let's dive in and explore the powerful capabilities of Python in the world of 3D software!
Code:
PICK SELECTION SET GET ATTRIBUTES IN MAYA
import maya.cmds as mc
Pick Selection
sel = mc.ls(sl=1)
Get Texture Node
file_node = sel[0]
Get Parameter Value
parm = '{}.fileTextureName'.format(file_node)
Get Parameter Value
parm_value = mc.getAttr(parm)
print(parm_value)
Set Parameter Value
mc.setAttr(parm, 'E:/ma/sourceimages/sloth_texture.jpg', type = 'string')
parm_value = mc.getAttr(parm)
print(parm_value)
PICK SELECTION SET GET PARAMETERS IN HOUDINI
import hou
Pick Selection
sel = hou.selectedNodes()
Get File Node
file_node = sel[0]
Get Parameter
parm = file_node.parm('file')
Get Parameter Value
parm_value = parm.eval()
print(parm_value)
Set Parameter Value
parm.set('E:/_behind_the_magic/_src/ASSET_statues.abc')
parm_value = parm.eval()
print(parm_value)
PICK SELECTION SET GET KNOBS IN NUKE
import nuke
Pick Selection
sel = nuke.selectedNodes()
Get Read Node
read_node = sel[0]
Get Knob
knob = read_node.knob('file')
Get Parameter Value
knob_value = knob.value()
print(knob_value)
Set Parameter Value
knob.setValue('E:/_comp/_out/drag_landing.mp4')
knob_value = knob.value()
print(knob_value)
