Underwater Bubbles | POP simulation - Houdini 19.5 (or any above 17)
Hey everyone! In this video, we are creating the underwater bubble effect from start to finish. It's a beginner tutorial, but we'll be using a few lines of VEX. If you're not comfortable with VEX just yet, it's fine - just skip these parts and you'll still be able to create pretty results!
If you're feeling a bit adventurous, you can add extra big-bubble elements with an additional Pyro simulation and share it in the comments! :D
But in this tutorial we'll be using a simple POP simulation and some of the basic POP nodes:
POPforce
POPdrag
POPfluid
Thank you for joining me today and I hope you enjoyed it! 😊
