I’m glad you guys still find that file useful. 🙂 By the way I just posted some previews showing a new feature that was driving me crazy and I think its very important when simulating fluids. I hope you like it! www.instagram.com/reel/CpWpCkHskic/?igshid=NTdlMDg3MTY=
Found out yesterday that you can apparently edit data directly in the spreadsheet for any geometry primitive, and the add-sop! Might even work for more nodes

example: www.shadertoy.com/view/Dst3D2
click to rotate through hue cycle
if you want a non linear distribution, change line 53 to something like `return pow(min(distToCenter / spokeLength, 1.0), 3.0);` or `return pow(min(distToCenter / spokeLength, 1.0), 0.25);`
the simpler version which is linked on the shadertoy comments, if you change line 63 on that bad boy you can see the distance from the offset center to the boundary parameterized to 0-1
“the spokes”

someone said , group + blast is much faster than an if statement + “removepoint()“ so I ran some tests (20 million points) and it is indeed true, although the absolute fastest is grouping using an integer attribute instead then doing “ @my_attrib>0“ in the blast (0.174 seconds compared to 1.594 for “if + removepoint()“, maybe this is helpful to someone 😄

it’s alright windows is weird for that
`C:\Users\user_name\AppData\Local\Temp`
“`nodes = hou.selectedNodes()
#get pane editor = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
#reset images
editor.setBackgroundImages([])
#get images
b_img = [img for img in editor.backgroundImages()]
for node in nodes: for parm in node.parms(): if(len(parm.keyframes())>0): #create image img = hou.NetworkImage() size = node.size() img.setRect(hou.BoundingRect(-2,-0.5,size[0],size[1])) img.setRelativeToPath(node.path()) img.setPath(‘$SIDEFXLABS/misc/stickers/emoji/SIDEFX_CUSTOM_EMBLEMS 08.png’) b_img.append(img) break editor.setBackgroundImages(b_img)“`
use this one instead
takes the size of node in consideration
https://www.reddit.com/r/Houdini/comments/q1c5vp/whats_a_way_to_use_the_operation_in_a_group_field/ – from some guy called “toad strum”? sounds like the sort of riff raff we’d never let in here

@mestela `Sure! Here’s a short rap about Matt Estela:
Verse 1: Meet Matt Estela, the man with the plan He runs Cg Wiki, where graphics fans Can find all the knowledge they need to grow And learn about Houdini, the software pro
Chorus: Matt’s got the skills, he’s got the drive He makes the graphics come alive With Houdini in his hands, he’s a king Making stunning visuals, that’s his thing!`
or this if you turn on ‘run on elements of array attributes’: “`c p@orientations = quaternion({0,1,0}*rand(v@positions)*10); “`
or “`c p@orientations = quaternion({0,1,0}*rand(@elemnum)*10); “`
after all that, this works for me with a duplicate: “` #include
