Hi! I just wanted to make a beginner tutorial on the most basic technique used to achieve magical style FX in Houdini which is particle advection. Sorry for bad audio and bad English especially from the latter half of the video. I will try to create better and more polished content moving forward. Hope you will find some helpful tips in this video! Also be sure to check the description for the HIP file and other links to gizmos / textures I ended up using. Something I completely forgot to mention is that you need to have ACES colourspace installed for your Houdini to achieve this final look. Here is a really good video about installing ACES on Windows: ua-cam.com/video/8zb3XjNBgRE/v-deo.html Key Takeaways: 1. Having a high enough point count and small points is the only way to achieve a smooth look when only using particle 2. Using the Attribute Blur node can help promote particle clumping / strings 3. Blurring particles in comp is a viable option but not a replacement for rendering too few particles, denoise nodes / motion blur nodes can be useful Thinking about covering some FLIP based magical FX or something more sci fi like laser / laser scans in my next tutorial. Let me know if there is anything in particular you would like to see.
This is a really amazing tutorial man! Very clear and concise and just watching you work I picked up so many little tricks. Thank you so much and would love to see more tuts in the future !
nice comp but just a little note on the Grain process, Grains don't show in bright areas of an image as they would in the darker areas, so I would reckon you key the highlights and invert them then use them as a mask for the Grain. and also where you had to luma key the inner core of the magic effect, rendering out the Emission pass would've saved you that process I believe
Great it gave you some ideas! The compositing part of my advanced velocities series goes deeper into compositing and utility passes. Also check out Voxyde or CompositingAcademy for fantastic Nuke content.
Great tutorial! I skipped through it to see what its about and I really liked it! so awesome what you can achieve with a smoke advection. I'll work it through in detail for sure now!
Great tutorial, I just don't get how the second pointvop you're using is managing to get the age and life attributes (that are driving the pscale) since you're deleting them both with the attribute delete early on. Could you enlighten me please :) ?
@@mnymanVFX Oh right ! That was simply it, I completly missed it! (I tried checking the file myself but somehow Gumroad didn't allow me to, might be a maintenance or somehting). Thank you for the quick answer!
Will the rendered ext or png files be done in Premiere or Davinci? Do you convert them to video files in Also, for example, when is it better to convert the color space in compositing software or video editing software?
Usually for myself I will use an OCIO ColorSpace node in Nuke and set it to output sRBG. I also make sure to set the write node after this to "Raw Data" when exporting. I usually export to .mov files from Nuke and convert them to mp4s with the Adobe Media Encoder. I have never used an editing software to do any of this.
The video is still processing so the quality is poor at the moment. Check back in a few hours and it should be 1440p! I ended up recreating the project because I lost my original file that I used for the teaser.
Hi ! please someone can tell me why when I rendered my images are correctly colored (nevertheless in the last frame rendered the entire image is overexposed) When I read my EXR file in nuke or in DJV for example, all my frames are overexposed, but during the rendered they aren't. I don't know what to do..
Are you using ACES? You have to tell Nuke or DJV the colorspace of your images probably. Try to press S in Nuke and change the "Color Management" drop down menu to OCIO.
@@mnymanVFX thanks for your replied, I am using ACES_1.2, it was difficult to find the good file to install but I found and installed it. I have already set the color management to OCIO 🥲 And just below I set the OCIO config to aces_1.2 And I tried all the working space LUT.. but I finally set it to « scene_linear (ACES-ACEScg) » the same as in the tutorial and it doesn’t work
Hey Mats! I would like to know if by any chance you could drop your socials such as ArtStation, Instagram or whatever they are in order to follow your work !! :)
Its rare to see a tutorial covering COMP too.
Thank you.
watching this when i get home. Thanks for uploading this for free ❤

I didn't find any issue with your English tho
please reupload files
This is a super humble, but super informative tutorial. I do not think that I came across a tutorial with a higher, ah, yes, nod, nod ratio ... THX
Such a great comment! Thank you so much Christian
Thank you for this! Glad to see Houdini to nuke videos
Great tutorial. Fast, effective and easily explained. Love seeing the Nuke comp as well. Looking forward to more from you!
ur channel is sooo good, pls do more videos!

That is actually a fantastic tip and something I didn't think about at all. Inverting it would be the more accurate approach.
Thank you so much for this tutorial. One of the best advection tutorials around here. It is all clear and focused.
Really great introduction to some Nuke workflows Mats! Currently making the switch from Fusion to Nuke and this gave me some great ideas/insights!

wow man thats just a great tutorial and great explanation...looking forward for more from you.Good luck
Thank you so much for pulling this out! I need to try this asap, once i get redshift license xD
I also talk about Mantra shading in the end. Maybe I can start doing more on Karma XPU once H20 is out.
@@mnymanVFX karma stuff would he great. So no need to look up for third party engines
Very good Tut. Please keep them comming!
Great tutorial! I skipped through it to see what its about and I really liked it! so awesome what you can achieve with a smoke advection. I'll work it through in detail for sure now!
Great tutorial!!! finally some magical fx in houdini, I've been searching this for a long time!
Thanks alot Kill3dge! Planning to do some more of these Magical FX moving forwards.
this is just AWESOME i can't wait to see more from you man such a blessing!
Thank you so much Mauro!
12:30 the blur SOP blew me away 😀👏. So simple to implement. Is it better then using an Advect by Gradient which is more cumbersome?
DAYUMMMMMM GOOOOD
6:21 I always wondered, does converting to 16bit reduces the quality of the Velocity volume? 😮
Hi mats do u know how I could constraint that simulation to a geometry bounds. ty for ur tutorials
Great tutorial, I just don't get how the second pointvop you're using is managing to get the age and life attributes (that are driving the pscale) since you're deleting them both with the attribute delete early on. Could you enlighten me please :) ?
Maybe the attribute delete is set to “Delete Non Selected”? Can check the file when I get back home as I don’t quite remember
@@mnymanVFX Oh right ! That was simply it, I completly missed it! (I tried checking the file myself but somehow Gumroad didn't allow me to, might be a maintenance or somehting).
Thank you for the quick answer!
how long have you been doing this for
there is a way to do the smoke part at sop lvl?
where can i get redshift engine
? i mean ive downloaded it.. but couldnt install it properly
why enabling opacity makes the render time longer?
it takes 10 second to render particles without opcaity
but takes 3 minutes with opcaity less than 1
Will the rendered ext or png files be done in Premiere or Davinci? Do you convert them to video files in

hi i'm not sure but it would be great if you could show us some shading with karma love your vids though
My newest videos cover a littlebit of Karma. Also this video shows a mantra-shader at the end which can be used in Karma CPU.
the quality is very low of the tutorial i just saw it. Are u able to upload it at least with 720p?

which houdini version is this?
Houdini 19!
I don't know how heavy is the scene but i can't even work with it...
I think I set the cooking to manual on the file. If you reenable cooking you should be able to work with it!
@@mnymanVFX omg thanks i didn't even now about that 😩
Try to speak a bit louder
