Very nice tutorial! Lots of tricks in here for an intermediate Houdini user. Thanks!

[@massimobaita7178]

Great! Thank You very much!

[@simoneadami5003]

Hi Vladyslav! great tutorial man! I really enjoyed. I was trying to make some r&d starting from your set up and having the particles colliding with a static object like a sphere but I'm experiencing some problem I can't solve. The points on the geometry are affected by the copy node and I see particles or pieces of the voroniod attached on it. How can I avoid this? I'm pretty sure this is for the variable PT that has @ptnum in the value but get really get how to bypass that and tell it to don't affect my static object. Thanks in advance if you can help. Cheers!

Hey, great tut! As of Houdini 19.5, the copy-stamp node doesn't exist anymore and I really suck at for-each loops. Does anybody know how to copy the voronoi fracture pieces onto the particles at around minute 15? Thanks!

[@ryan3dartist]

Hi! how would you add rotations to the debri?

[@spacetimelapses3988]

oh my gosh i really want to try that explosion but i couldn't never find a good tutorial ;)

[@whatsup1439]

Hi how would you change the color to more pyro-ish instead of rainbow?

[@Arcron]

How did you change your Houdini network background to the grid? 2

[@reecefranklyn7092]

How would I export this out for Cinema 4D and Octane?

[@brendanthompson2082]

anyone have the VEX written out? I'm new and am making some syntax errors I can't find.

[@fudge500]

Hi Vladyslav, thanks for the tutorial. I can't seem to transfer the colour to Redshift. I've added the colour channel in the Redshift Volume node but nothing seems to change. Any thoughts? Running version 17. Thanks

[@fudge500]

Ignore me, have solved it

[@mrblackyblack1053]

How to solve, please waiting for answer

[@smyrkphace]

Cant seem to get the second dop net to register the vdbfrom polygons as a source. As soon as you connect the pyro solver you get a bounding box, I follow exact steps and its not showing the vdb bbox even when check solve first frame. any ideas?

[@arielenriques]

When I try to copy the pieces to the particles, for some reason I get the entire sphere, not the pieces. I check again but everything looks like you did

[@mrblackyblack1053]

Main object - sphere1 - (smoke in the end of video) , redshift cannot see it. No RenderView Picture. Any Ideas ? Please Help...

[@Ra00Da]

Good tutorial, but sometime you go too fast.

[@petermarks9455]

Hi, great tutorial, but I have a syntax problem within the Object Merge. For Object 1 I use /obj/sphere1/Fracture_OUT. That seems fine, but for the group I have piece’stamp(“/obj/sphere1/copy1”, “PT”, 0)’ and that does not work as a valid group. I’m using single quotes between piece and stamp and at the end, piece’stamp(….)’. I think that is what you show, but it’s not working. Does anyone know the correct syntax for this entry in the Group1 line? If I just use “obj/sphere1/copy1”, “PT”, 0 I get a valid group just not the correct group (without piece or stamp). Thank you!

[@smyrkphace]

Hey this had me for a sec too. Its a ` backtick. depending on your layout it lives under the ~ sign, top left of your kb. Add this and the function color returns.

1:24 how did you visualized normals on the sphere?

[@MotionDesignersCommunityTV]

Attribute visualization in Houdini 1) You can right click on a node, display node parameters and click on an attribute, it will display it in the scene view. 2) You can also click X on a node, it will append a visualize node, you can set it to visualize any kind of attribute. 3) You can customize your own visualizers in Houdini, just right click on the button at the bottom right of the scene view. You'll be able to set new visualizers. 4) You can Vizualise some attributes with the Color node, by setting it in "Attribute from Ramp" :) In the current case, and if you're not familiar with all those methods, I'll simply suggest to use the first method, simply display node infos and click on the attribute :) Cheers, Max

[@lynked]

Motion Designers Community thank you I really appreciate your help but there's a problem that after writing VEXpression as showed and clicking on the attribute nothing changes But I can see at the geometry spreadsheet that v[x] v[y] v[z] are calculated

[@MotionDesignersCommunityTV]

@@lynked Hit the D key! Did you inspected the scene view parameters? Cheers

[@lynked]

Motion Designers Community absolutely, I tried literally every checkbox but it seems there's nothing similar to the ones in the video

[@lynked]

@@MotionDesignersCommunityTV omg I just did it Thank you so much for your help you're the best All I had to do is to click visualization box in the scene view and visualize v attribute with not the point but vector (for those who is having the same problem) Cheers :)

[@odiagam5755]

i had to download houdini 18 just to follow to tutorial because newer version doesn't have copy stamp :(

[@smyrkphace]

Dude either started smoking cigars, or his balls dropped at 17:45 lol. Thanks for the quality tut. Im still stuck tho haha! see below

[@vladyslavlavrenov9167]

Hahahaha, this is a fucking hilarious comment XD Thanks man

[@AI_cinematic]

What would you study in such lessons. Why is you neurotically twitching with your mouse and jumping into sections. The crater and the method you found the most difficult.

[@doziefranklin2490]

Tutorials like this is why Houdini is scary to beginners. Cause WHAT THE F###K!

[@dropsyou9213]

only version 18 ?

[@vladyslavlavrenov9167]

No, 17+ would be fine too. That's why I used legacy pyro here, instead of sparse.

I think you are not fast enough, please do it even faster so that its really not follow able..... it's a tutorial dude, dont rush that quick! God damn😂

[@AshleyGlover]

I agree, lucky KZbin does have the slow down function.

[@AshleyGlover]

On Houdini 18.5.499. I am getting an error on the "init" function on the attrubute wrangler 2: #include "voplib.h" vector inti_v = normalize(@P); float freq = chf('freq'); float offset = chf('offset'); float noise = xnoise(@P * freq + offset); rand(@ptnum) * 2; noise = vop_bias(noise, chf('bias')); @v = lerp(init_v, @v, noise) * 15; @v *= noise; Any idea what what is wrong?
