I created a noise pattern with point vop and saved it as ‘userParam’ attribute.
I want it to control ‘refraction intensity’ so that I can see white area clear and black area solid. But whenever I multiply ‘refr_int’ with the attribute, ‘userParam’ it all goes to black and solid.
What did I do wrong?
Thanks for your help in advance,
Hb

that's strange. i'm using v15.5.480 mac version.
indeed wiring a color to Ce input is working.

there must be something i missed.
in a shader builder i checked 'enable emission' but nothing happens.
what did i miss?

hi,
i know i'm missing something but i can't figure it out.
i have a circle and a line. circle gets red color from line through attribute transfer.
then i created an attribute 'redValue' and wanted to use @redValue to control the scales of copied grid. it scales everything together not individual copies. what did i miss?
appreciate your help!

something simple but can't figure it out.
i have a setup with attribute vop, controlling opacity by distance.(attached pic)
i used bind export with attribute name “Alpha.” btw, is this the right way to set up opacity?
it seems working until i use copy node(i checked ‘use template point attributes). in geometry sheet, all alpha value turns into ’0'. and when i render i rather see every cube as if alpha is ‘1’. what did i miss?
how do i sucessfully render alpha?

hi
i have an object imported from c4d. read some articles on how to import from c4d.
but how can i access the data like point's position? as you can see in geometry spread sheet, all the point data is gone. it treats the geometry like a primitive i think; it has only one single point.
thanks in advance,
hb

that's great and simple idea. thanks!
is there a way to do it in an attribute vop? or using connect, partition?

hi,
if i want to have all the polygons displaced while being parallel to the floor how should i approach?
i facetted with unique points and used turbulence noise with displacing along the normal. but of course it's not good enough.

Houdini Learning Materials » wrangle error with divide "/"?

is wrangle working with division in float?
when i tried
f@result = @ptnum / (@numpt-1);
it supposed to give me gradual float values from 0~1 but it didn't. everything returns 0 except the last value with 1. it works as if floor() has been applied.
anything wrong i did?

so it seems like undefined value doesn't work with {}.
because even vector statement, @P += {0,2,0}; was working but not @P += {0,random(3),0};.
thanks,

going through wrangle introduction tutorial and i'm new to vex/wrangle language.
i'm doing a very simple thing, a grid with random y value.
when i set “rand_y” variable it works fine.
v@rand_y = set(0, random(@ptnum), 0);
@P += @rand_y;
but when i wrote down everything in a line i got an error;
@P += {0, random(@ptnum), 0};
why is that?

as a beginner which variables are working in POP, DOP, or VOP is the most confusing to me. it would be amazing if there is a list or something that i can refer to.
could you explain what you meant by “put down a POP VOP DOP, dive in and inspect the name of the outputs on the Global Variables VOP”?
this seems like what i was looking for. i want some reference example where i can look into it. this will sure solve a lot of my questions and significantly reduce my postings. :-)
thanks jeff,

If you forget the globals, just put down a POP VOP DOP, dive in and inspect the name (not label) of the outputs on the Global Variables VOP.
