Houdini KARMA - Cloud Rendering pt3

The final part to this series is all about outputting render layers and AOV's for us to composite our final images. I'll take you through the Karma render ROP, How to setup different AOV's and render them all into 1 file.
After that I take you through my basic compositing workflow in Nuke when rendering clouds.
Check out the collaboration I did with Action VFX and grab yourself some high quality cloud vdb assets for your next project!

SO good. Thank you. Looking forward to more Solaris and Karma. Appreciate your work!

Great video mate! Would love to see some more compositing specific stuff in the future though!

[@wewantmoreparty]

Nice like you do 3D to compositing videos

[@mzigaib]

Awesome video man, thanks!
I will be looking forward for more of those 😃

[@bazuka0000]

great tut mate, but if u ask me rendering volume/clouds is still way to slow even with the latest hardware...

[@dennisbranson7816]

Great work! Can I ask how are you able to preserve big shapes while also keeping small details. Is it no turbulence and just disturbance based on density? Or maybe vel? Mine just turn into disorganized mess. But then again, I tried with axiom cause my pc dies with pyrosolver

[@breakyourcrayons]

Hey Dennis! Yes, fine details are created by a lot of disturbance. Disturbance is confined to small surface areas and turbulence forces affect the entire sim as a whole. Turbulence change the entire shape over time and Disturbance just affects the area where you want it.
A cover it a bit better in my course but it’s all Pyro. I haven’t used Axiom all that much but I would crank up the disturbance if there is that control 👌🏻

is this Ai Voice ☺😮

[@breakyourcrayons]

lol, I had to use an ai filter to fix the audio from my mic. I bought a new mic already so next videos won’t need that 😅
