Kalyra Posted May 3, 2017 Share Posted May 3, 2017 Hi, I'm a beginner at Houdini so forgive me if I am not familiar with a lot of things. I have converted some moving geometry (alembic) into a cloud and it is moving quite quickly. I want to be able to alter the animated noise effect on my geometry so that it doesn't use world space noise as it moves too quickly. I understand that this effect works well with slow drifting clouds but my geometry is not moving slowly. If I can't alter the rate at which the noise animates then I would also be interested in removing it entirely. At the moment I am using a cloud node and a cloud noise node. I'm unsure about how to achieve this so any help would be greatly appreciated! Quote Link to comment Share on other sites More sharing options...
Atom Posted May 3, 2017 Share Posted May 3, 2017 (edited) Here is an example of the cloudnoise node configured for static operation and an alternate configured for animation. Basically you animate the Z-Offset of the noise and allow advection for animation, otherwise leave those option off or non-animated.

This is exactly what I was looking for! Quote Link to comment Share on other sites More sharing options...
Kalyra Posted May 5, 2017 Author Share Posted May 5, 2017 (edited) I looked at your file and everything seemed to be working, however when I started using my alembic file, the animation affect continued no matter which static or animated node i was viewing. I replaced the font and extrude node with an alembic and it still continued to animate. What am I doing wrong? Or does this method not work with abc files?

Atom Posted May 5, 2017 Share Posted May 5, 2017 Can you post your .abc file? Quote Link to comment Share on other sites More sharing options...
Kalyra Posted May 5, 2017 Author Share Posted May 5, 2017 Here's my abc file, thanks for taking the time! dolphin_ani_248_406.abc Quote Link to comment Share on other sites More sharing options...
Atom Posted May 5, 2017 Share Posted May 5, 2017 (edited) I tried your file and it seems to work for me. I did unpack the Alembic and tweak the orientation with a transform. And also animated the tail with a Bend. ANIMATED CLOUD STILL CLOUD ap_fast_moving_cloud_ALEMBIC.hipnc Edited May 5, 2017 by Atom Quote Link to comment Share on other sites More sharing options...
rileycoyote Posted April 11, 2019 Share Posted April 11, 2019 Hi I'm new here and I successfully got this animated noise working. I'm looking through the paramaters and trying to find a way to animate the cloud 'breaking apart' and the pieces coming together to form the shape. Any thoughts? Thanks!
