Hey thanks for the tutorial! Really awesome effect! The reason Cd.r doesn't work on the color node is because that parameter is designed to expect an attribute. Any parameter that expects an attribute can't read just a single component of that attribute because the dot operator only applies in VEX context. Some parameters can read VEX which is why Cd.r works in other parameters (like Group parameters). Really confusing, but that is how its been explained to me!
7:50 I think the Cd.r not working might be because it looks for a full vector? Also, you don't need the yval, you can just input Cd there and it works the same. Great tutorial, thank you!
thanks for these tips mate.Im having issues with Vexpression and im quiet new in houdini.it says : Error Invalid source /obj/geo1/pointwrangle1/attribvop1 Error: Invalid subscript for type: float.r (3,16:18) Warning: Using uninitialized variable: amp (8,74:76). Warning Invalid subscript for type: float.r (3,16:18) Warning Using uninitialized variable: amp (8,74:76) Any ideas how to fix it?
Hi, Nick! Great as always. Is it possible to somehow use this color attribute to shade it in C4d Octane and also get that changing gradient? I saw you create groups of objects based on color to shade objects in Octane in one of your tuts. But here, the color is always changing.
Hey Dennis! Yup, its possible :) Long story short - I tried exporting this to C4D but the viewport is 0.00005FPS and Octane crashes. BUT it might be just my setup and pc. Ill record a tutorial this week (probs thursday) and explain how to import abc to c4d, cause there are a few things that will make my reply here in comments too long and possibly unclear :D
@@nickmedukha thanks! Looking forward to it! The crashing definitely happened to me when I tried rendering alembic as hairs in Octane for another tutorial. Would also be great to see some tuts on Vops cause all the info is mostly about noise displacement inside Vops. Have a good one!
@@florian7407 Hey Florian, there's a setting in your default camera to select everything based on an ISO volume of the camera view. so that you don't have a ton of extra data in your scene slowing things down
Thats me using Redshift first time, so if you have any suggestions on better render settings - you are more than welcome to share them here!
Code:
vector freq = {1,1,1};
vector off = @Time/10;
float amp = @Cd.r;
float rough = 0.6;
float atten = 1;
int turb = 6;
vector activeV = anoise(v@P * freq + off, turb, rough, atten) * (vector)amp;
v@P += activeV;
v@Cd = fit01(activeV.y, 0, 1);
f@yval = v@Cd.r;
great. thanks man. bookmarked for laters! 🤩
Always welcome!

Hey Caleb! Thanks a lot for explaining that to me! Still strange tho :D But yeah, just feels wrong adding another param just for the coloring :D
Finally on Redshift thank youn so much
haha no prob! glad you liked it!
awesome tutorial as always
Thank you :)
Just what I needed in time, thank you!
yay! Glad to help :)
Thank you so much for this :)
Always welcome :)
Great tutorial as always ❤️
Thanks a lot, Abdullah!
very good tutorial as usual! Thank you!
Glad you like it :)
Bro you the best
Oh thank you!

oh, you're right! thanks a lot mate!
I'm a vop kid. Saw your vex I was like yaaaaa... uhhhhh. VOP plez, for the smoother skull kids

This looks cool, might give it a go, I've uploaded a waterfall simulation and might use this with it.
Thanks man!
can u not use X particles and c4d falloff to create the same effect?
how to texture this in octane in houdini???

Could you drop me a few screenshots of your scene in Instagram @nickmedukha? :)
i had a similar error, check the uppercase and lowercase

I might be missing something, but...did you skip particle part? This is all geo.
You could just blast away all your empty points that aren't in view of the camera with the camera capture volume!
Wow thats super handy! Thanks so much man!
Could you please explain in more details what you mean by that? I'm intrigued. Thanks!

anoise stands for "Alligator Noise" Thank me later !
not worth paying for render farms , if u can afford 20 + $ for such simple renders u can afford gpus lol
