In my scene, I want an object to fly through the clouds, causing the clouds to react. I've got the look that I want with the clouds, but I'm not sure how to stop them from rising and constantly moving. I want the clouds to be essentially static, maybe with some very slight movement, but then as the object flies through, they'll react appropriately. I've got an initial state that I like (not shown in the video below), but once I start the animation they rise like smoke. I can't cache the simulation and then hold it on a specific frame because I need them to be active so that they'll react to the object realistically. I also don't want to cache it and hold the frame until the object passes through, because then it'll look weird for the clouds to be stuck in a position, then suddenly all start to rise immediately.&nbsp;<BR /><BR />I fiddled with settings and googled around, but I can't get anything that does what I'm looking for. Any help or suggestions would be massively helpful. Here's a video of the closest I've been able to get to what I want:</P><P><div class="lia-vid-container video-embed-center"><div id="lia-vid-6322579000112w400h220r788" class="lia-video-brightcove-player-container"><video-js data-video-id="6322579000112" data-account="6057940548001" data-player="default" data-embed="default" class="vjs-fluid" controls="" data-application-id="" style="width: 100%; height: 100%;"></video-js></div><script src="https://players.brightcove.net/6057940548001/default_default/index.min.js"></script><script>(function() { var wrapper = document.getElementById('lia-vid-6322579000112w400h220r788'); var videoEl = wrapper ? wrapper.querySelector('video-js') : null; if (videoEl) { if (window.videojs) { window.videojs(videoEl).ready(function() { this.on('loadedmetadata', function() { this.el().querySelectorAll('.vjs-load-progress div[data-start]').forEach(function(bar) { bar.setAttribute('role', 'presentation'); bar.setAttribute('aria-hidden', 'true'); }); }); }); } }})();</script><a class="video-embed-link" href="https://forums.autodesk.com/t5/video/gallerypage/video-id/6322579000112">(view in My Videos)</a></div></P> Wed, 15 Mar 2023 00:26:11 GMT https://forums.autodesk.com/t5/maya-dynamics-forum/how-to-stop-slow-cloud-simulation/m-p/11821783#M274 Taylorcbray 2023-03-15T00:26:11Z https://forums.autodesk.com/t5/maya-dynamics-forum/how-to-stop-slow-cloud-simulation/m-p/11829677#M275 <P>Okay, so I figured out how to achieve the effect I wanted.
