wireframe opacity

[Anonymous]

I really need to turn down wireframe opacity so it’s slightly transparent, especially when im working with lidar scanned sets and matching meshes on plates.

While the feature is documented and available under "Set wireframe transparency," I needed a dedicated tool in my workflow to quickly toggle between 0.25 and 1 alpha. Therefore, I created this Python script, which you may find useful.

import maya.cmds as cmds
import maya.mel as mel

def set_polymesh_dormant_alpha(alpha):
    current_color = cmds.displayRGBColor('polymeshDormant', query=True)
    cmds.displayRGBColor('polymeshDormant', current_color[0], current_color[1], current_color[2], alpha)
    mel.eval("updateColorPrefUI()")

def create_alpha_control_ui():
    if cmds.window("alphaControlWin", exists=True):
        cmds.deleteUI("alphaControlWin")

    cmds.window("alphaControlWin", title="Polygon Alpha Control", widthHeight=(200, 100))
    cmds.columnLayout(adjustableColumn=True)
    
    cmds.button(label="Set Alpha to 1.0", command=lambda _: set_polymesh_dormant_alpha(1.0))
    cmds.button(label="Set Alpha to 0.25", command=lambda _: set_polymesh_dormant_alpha(0.25))

    cmds.showWindow("alphaControlWin")

create_alpha_control_ui()
