You probably want to use radius instead of SSS Color (or both :O )

Your prim path on `rendergeometrysettings1` is wrong, setting it to `/cyc` instead of `loplastmodifiedprims("../box")` fixes it

Main issue is that you're typing the LPE's into the wrong parameter, secondary issue is using the wrong quotes.

Or use the fuse node in match attribute mode and disable the `snap distance` & `output position`. That would only keep one of each value

I did see in the changelogs(20.5.110) that acceleration blur is now supported in the hair procedural, I assume then you would at least get curved motion blur for the hair procedural?
Or maybe this was always supported if the guides had v@acceleration

I think it's now recommended to use 
pythonX.Ylibs/pythonrc.py|ready.py|uiready.py
As you can have multiple of them
See docs for info on the difference between them:

You need to indent after the if:
paneTab = hou.ui.paneTabUnderCursor()
if paneTab.type() == hou.paneTabType.Parm:
   paneTab.setFilterMode(hou.parmFilterMode.NonDefaultParms)

   toggle = not paneTab.filterEnabled()
   paneTab.setFilterEnabled(on=toggle)

Partition by comparison can do this, a bit cumbersome to setup if you don't know the work item counts up front. But seems to work well enough

Technical Discussion » Radially distorted bokeh with the physical lens shader?

User Avatar

It is somewhat possible with the lens shader (cpu only), I'm not completely sure it actually does any of the Optical Vignetting though.
Here is what I got when I played with something similar, rotating the bokeh and playing with the anisotropy




Attaching the hda if you want to take a peak beneath the hood, assign the vop as the lens shader(karma CPU only)

The problem is that a vdb does not have v@P, use @nameofvolume.pos instead
https://www.sidefx.com/docs/houdini/vex/ocl.html#vdb-binding-methods [www.sidefx.com]

// Bindings
#bind vdb &density float

@KERNEL
{
    float3 pos = @density.pos;
    float d = @density.worldSample(pos);
    d *= 0.5;
    @density.set(d);
}

It's possible with a shelf tool:


Script code
paneTab = hou.ui.paneTabUnderCursor()
if paneTab.type() == hou.paneTabType.Parm:
    paneTab.setFilterMode(hou.parmFilterMode.GraphSelectedParms)    
    
    toggle = not paneTab.filterEnabled()    
    paneTab.setFilterEnabled(on=toggle)

Currently the hou.parmFilterMode... does not match up with the menu, so you need to use the "graph selected parms" for it to select "non-default parms" I'll submit a bug report for that.
