Houdini Tutorial - Thanos Inspired Portal Effect

Показать описание

In this tutorial, we go over how to recreate the Thanos portal effect from Avengers: Infinity War.

We go over how to create pop networks that can be converted to VDBs that can then be used for smoke simulation.

Hey everyone, if you are using a version later than 17.4.12, please adjust the following settings:

-Keyframe dissipation on the pyrosolver to 0.7 at frame 1, 0.5 at frame 48 and remove the keyframe at frame 72.
-Adjust boundary size on the smoke object to 8x8x12
-Ensure sufficient padding on the gas resize (Padding of 4, and then 2x2x2 on both upper and lower scale or 8 on main padding alternatively).

This should remove any issues with clipping and dissipation. The reason that this became an issue is due to a change in 17.4.12 where the following change was made: "A bug has been fixed in the smoke solver that affected simulations with animated timescales, cooling, and temperature diffusion rates. The solver works correctly in those regards now, meaning old simulations to which this change is relevant will produce different results." This resulted in keyframing not working as intended.

Hope this helps solve the issues that many of you have encountered. Thank you for bringing it to my attention!

Laughed so much when Thanos came out of the portal ;D gj!

Hi, I'm new to Houdini and doing this tutorial in version 19.0.561. Just wanted to post this for anyone who may have been running into the same Attribute Noise node problem I was having. Since SideFX changed the Attribute Noise node in version 18.5 it was hard to get the same effect Nine Between got, but the closest fix I found after searching was to use an Attribute Adjust node instead of the Attribute Noise. Attribute Adjust allows you to change the Pattern Type to Noise and seems to work how the Attribute Adjust works in the tutorial video

Probably one of the best ones you did! Please upload more often!

Kinda deceiving having to go through the whole tutorial to end up using a custom made node made available only to patreons. But to each their own. Thanks for the teachings...

Great tutorial, thank you for this one! One thing I'd like to point is that I ended up downloading v17 because the Attribute Noise node changed significantly and since I am new to Houdini I was not able to replicate the settings on the new nodes. Still it opens fine in v18.5 and renders much faster. So this is well worth working through if you are looking to use this effect in your next project.

I don't get any of that but it's so interesting to watch. keep producing this kind of video. I loved it!

A really great tutorial! Wouldn't mind hearing some reasoning behind the scaling decisions of the fields though. I mean, if You'd be willing to go into a little more detail on why density, vel, temperature where set one way in SOPs and then imported with different values into DOPs, it would be greatly appreciated. Any specific reason for not setting them up to that size already in SOPs? I see Houdini shelf tools do the same.

A great fast paced and informative tutorial anyway! Thank You!
