Houdini KARMA - Cloud Rendering pt1

In this tutorial I'll be taking you through the basic setup for rendering cloud VDB's inside of Houdini 20 using Karma and the USD stage.
Part 1 is just a quick overview using the default Karma Cloud Shader. Part 2 will dive into more detail and go over the shading process in more depth.

Something Interesting! Thnks!

Breaking the volume bounce limit expression breaks the weighting for the extinction, I am not sure that's a great idea.
Also, setting the volume bounces globally means every volume you render in that render pass will inherit it regardless of extinction weighting or if you wanted
for example no bounces on a specific volume.

YESSSSSSS !!!!

[@breakyourcrayons]

lol, thanks bud! I posted part 2 as well which goes into all the details :)

Hi, why can render volume in realtime and even on a website ??? Or that's bake texture to a mesh ?

[@breakyourcrayons]

Hey hey, if you are referring to the ActionVFX website, it’s just a turntable. Still images with a camera rotating around 😅 rendering real-time on a website would be crazy lol

not using blender anymore?

[@breakyourcrayons]

Still using Blender :) but currently doing a project completely in Houdini to see the difference. I still think Blender looks better but Houdini can do something’s that Blender can’t.
There is a nice update in Blender 4.1 that will fix some issues as well. Blender is amazing, I really enjoy using it 🙌🏻
