Deep Dive into Ocean Spectrum Node in Houdini

[@nikosrueter9949]

anyone who makes free tutes is a goat :)

[@bubblepins]

THanks!

[@xcombxcomb6781]

love hearning your voice! Thank you for posting! Hope to see more interesting and not boring tutorials!

[@bubblepins]

Yeah this one was more on the boring side, sorry. I needed a few videos explaining some of the core concepts in preparation for an ocean collision tutorial but it requires knowledge about ocean and flip combined together. There should be one more FLIP video coming up and then the next one after that I can explain ocean collision which uses the previous videos for core concepts.

This is soooo helpful I'm glad I found your video, thank you so much!!

[@bubblepins]

I'm glad you like it!

[@MONEYVAL9]

I really like your video, this give us more power than over the top tutorials, we can be more creative knowing about the tool rather than a specific effect .

[@bubblepins]

Awesome! Thanks, it makes me feel great knowing people appreciate the basic foundation rather than specific effect!

[@douaaal-mgoter5260]

it is very helpful and well explained.. thanks alot

[@bubblepins]

Thanks for watching!!

[@sargstacker5579]

Thank you so much for making this! Really helped me.

[@allmedia320]

need more deep dive videos into particular nodes which are used often in Houdini please

[@bubblepins]

Most of my videos are covered with deep explanations! Check out some of the latest Pop Up Live Stream videos on Vellum: kzbin.info/aero/PLqovuMX-teVPdqtRpfznUk-mdwFlOJROf

Thanks for the help

Thanku so much it helped me a lot :)

hi, on Houdini 19.5, Min Wavelength parameter in Amplitude of Ocean Spectrum does not function, changes nothing when the slider is dragged. is it a sort of bug or mine is so??

[@pontosinterligados]

Thanks! is there any way to affect attributes by a mask? say, the same as using to mute the effect, but instead, to change amplitude or wind, depth...(or propagate on the spectrum, values of properties embedded on the scatter points used to source it)

[@bubblepins]

You can try inverting the mask, sorry if I'm misunderstanding the question correctly. Hope that helps!

[@pontosinterligados]

@@bubblepinshey thanks for the response! I’m rotating the angle of scattered points to face the direction of a landscape, so to achieve this I just had to open the spectrum node e set “orientation” node to “add”, instead of default “set’.

[@bubblepins]

@@pontosinterligados Nice trick! I didn't know about that!

[@psychedlicavfx6646]

OMG! this is such an AWESOME explainer video. You're like a Duncan Brinsmead and Dr. Jerry Tessendorf combined with (a smarter version of) Ellen Page! Thank you so much! P.S: I also do some VFX work on my channel but its nowhere near as good as your work. P.P.S: Do you have a corsair AIO cooler in your system?

[@bubblepins]

You're too kind!!!

[@microcam6375]

Is there a way to output this mask from Houdini as a texture?

[@bubblepins]

The mask from the Ocean Spectrum node? I'm not sure. But I know you can output the Ocean displacement as animated textures. So you could theoretically output one set of Ocean displacement WITH the Noise Mask on and do another Ocean displacement WITHOUT the Noise. Then you could subtract the two images, that should give you the mask. Hope that helps!

[@microcam6375]

@@bubblepins Thanks Bubble Pins. I will give it a try!

[@samcare7753]

@@microcam6375 sidefx have a more in depth tutorial on their website and youtube channel which goes over exporting the mask. thanks @bubble pins I feel like your videos are always the best videos to watch as the first video on a new subject. I also really appreciate how you don't rely on shelf tools, cause all that auto dopnet stuff can get really messy at the obj level. thanks!

hello,how to render this out with redshift?

[@bubblepins]

It should work out of the box, because the Ocean displaces the actual geometry like a vertex animation. It would render out like any other geometry. You can throw on a transparent material on the Ocean floor and then remember to use lighting with high contrast. Hope that helps!

[@kyozhan7172]

@@bubblepins so you never use the spectrum mask for rendering?there are spectrum and spectrum mask need to loaded in materail setup for rendering

[@bubblepins]

@@kyozhan7172 If I remember correctly the spectrum mask is for things like making the ocean a little more calm like to negate the waves in the area where the mask is OR if you wanted to increase the ocean wave noise in the area where the mask is located. It's to manipulate the Ocean waves with more control. Hope that helps!

[@kyozhan7172]

@@bubblepins ya,that's it.I know how to set up the specctrum mask,but don't know how to render it out.

[@bubblepins]

@@kyozhan7172 You don't really render the mask, but you render the Ocean grid. After you put down the Ocean Evaluate node, it displaces the grid geometry and you can render the grid geometry like any other regular geometry. Hope that helps!

[@Rockerhuni]

cool!

[@xcombxcomb6781]

Oh, sorry i didnt mean to say that, on the contrary, it isnt compare to what i have heard before.

[@bubblepins]

oh that's fine. lol
