How to subdivide/split a face by points in a grid pattern Oct. 15, 2025, 2:26 p.m.

Hi,

You can do this easily with an extra float parameter called bysize for x and y divisions respectively:

max(2, ceil(ch("sizex") / ch("bysize")))

max(2, ceil(ch("sizey") / ch("bysize")))

Thanks, man,

You are the best!
I was hoping to toggle between these two.
WorkLight or Scene Light.
Is that possible, too?

I think that's not possible because there is always some work light mode available. There is no off option. Even if the toolbar shows off, the work light still reports the current one used.

Hi,

This should work:

def toggleWorkLight():
    with hou.undos.disabler():
        viewport=getPaneTabUnderCursorOrFirstInstance(hou.paneTabType.SceneViewer)
        settings=viewport.curViewport().settings()
        settings.setLighting(hou.viewportLighting.Headlight)
        new_type=hou.viewportWorkLight.PhysicalSky if settings.workLightType()==hou.viewportWorkLight.Headlight else hou.viewportWorkLight.Headlight
        settings.setWorkLightType(new_type)

The other types are listed here:

hou.viewportWorkLight.Headlight:
Single over-the-shoulder distant light.

hou.viewportWorkLight.Domelight:
Environment light with optional texture map.

hou.viewportWorkLight.PhysicalSky:
Outdoor lighting with a distant and environment map based on the sun position and atmospheric conditions.

hou.viewportWorkLight.ThreePoint:
Three distant lights set up in a classic three point lighting arrangement.
