TOTAL DURATION: 1h 6m 38s

In this lesson, you will smash a wine glass then slow down time to hold onto the big splash. This effect involves both an RBD simulation for the shattered glass and a fluid simulation for the wine. You will learn how to set up the dynamic simulations. Visual effect shots often involve a combination of different solvers.

You will also use a retime node to slow down the simulation when it is at its most explosive then reverse time to return to the starting point. You will then move the simulations into Solaris/LOPS, set up lights and a camera, then render the shot using the Karma XPU renderer.

This lesson includes a step-by-step PDF which you can use to follow along the lesson supported by video tutorials.

    Hey man, thanks for the tutorial i really enjoyed the process and the tutorial was a good stepping stone for beginners i loved the pacing that you taught in One thing i would like to point out is you could have included how to change the resolution and and the orientation.

    Really enjoyed, thanks so much. My fluid turned out pretty "gloopy" though. Trying to figure out why and I'm wondering it it's the scale because my wineglass ended up about 7meters tall from what I can see. That also made the fluid really big. Did I miss a step? I tried re-watching and I didn't see anything about that. Thanks again

    hello,
    thank you for that tuto, but retiming doesn't work in wine_sim = everything jumps away .. is that because of 20.5 version I use? other? I tried many times following your tuto..

    thanks

      Oh, no way, dude! For some reason, your comment appeared right after I posted mine about the same issue. Did you find a solution? I guess nobody is going to help us in the coming days since it's Christmas.

      • Balonich 9ヶ月 前  | 

        I should also mention that I use Houdini 21, so perhaps there's something we both missed. I also haven't found anything in the step-by-step PDF guide.

      I solved it, read my comment bellow in a different thread. I hope this will help you as well.

    Hey, hey! I'm stuck on lesson 4 at the point where I need to add the copied Retime Node to the wine simulation - for some reason, the liquid is no longer static and is moving throughout the volume, as if the retime animation is hanging its position. Has anyone else encountered this and knows how to solve the problem?

    • Balonich 9ヶ月 前  | 

      I noticed one thing in the PDF step-by-step guide on page 11, step 7: the collision settings are described, but I don't see them in the nodes. These settings were probably exist in older Houdini versions.

      • Balonich 9ヶ月 前  | 

        SOLVED!
        What I did:
        1. Changed Storage Type to Points in the Fluid Compress node (missed this step during the tutorial, not sure if that actually the cause)
        2. In the file cache, saved the entire thing to disk once again

      Well, misclicked for sure... If any moders are here, remove this entire thread.

    Hey, I've been stuck for a couple of days now. When I'm setting the shot to render the wine fluid is in the wrong place. Instead of being in the glass, like its in the OBJ, its floating slightly below the glass. I've been trying to figure out whats going on for a couple of days now and I've got nothing. I re-cache everything, reloaded everything but i cant figure out what going on.
    Has this happened to anyone as well?

  • Yomster15 8ヶ月, 1週間 前  | 

    Hi, I'm currently on the 5th video, where I'm adding the wine USD via the sublayer, but my computer restarts, citing an issue. Whenever I open the file, the computer automatically restarts. Has this happened to anyone else? Are there any suggestions on how to resolve it?

    when i set the background image and try to zoom in and out holding alt key and right mouse button, the background image is not getting xoomed in and out. only the grid scale is getting zoomed in and out. can anyone tell me how to solve this

    • rmagee 1ヶ月, 4週間 前  | 

      Are you working with Houdini 22? There is a bug in the production build that causes this to happen. Download one of the recent daily builds - It should be fixed now.

    • akashdeepparmar498 1週間, 2日 前  | 

      You can use the reference image instead.

    In part 1, when I select the face it selects the entire glass. How do I fix this? I pressed A like in the video but its still not working. Help!
