01:34 – Preventing UV Seam Errors
02:34 – Creating Initial Particles
04:07 – Setting Up The FLIP Sim
04:37 – Linking Particle Separation
05:12 – Tweaking Sim Parameters
07:45 – Adding Forces To Stir It Up
08:32 – Using VOP Functions in VEX
09:37 – Creating Noise Input Parameters
10:55 – Creating Curl Noise
11:54 – Creating Force Perpendicular to The Bubble’s Surface
14:40 – Testing It
15:13 – Transferring Sim To Bubble
16:16 – Adding Gravity Effects To Bubble’s Wall
18:53 – Distorting The Bubble
19:33 – Setting Up Rendering In Octane
21:48 – Shading The Bubble
23:46 – Image Texture As Bubble Detail
26:21 – Noise As Bubble Detail
27:54 – Adding More Detail (Gradient Trick)
29:13 – Infamous Last Words

By now it might have become apparent that Mo might be a bit fixated with soap bubbles and soap films. We covered Minimal Surfaces, soap film shading in Octane and in Redshift.

Yet we deliberately omitted one crucial step in rendering nice soap bubbles: Creating those intricate swirls on their surface. Rejoice – in this video Mo will shed light onto what it takes to set up a fast FLIP sim resulting in high detailed swirls.

29:13-臭名昭著的遗言

到现在为止,Mo可能已经被肥皂泡和肥皂膜固定了一些。我们介绍了“最小表面”,辛烷值和Redshift中的肥皂膜着色。

但是,我们故意省略了渲染漂亮的肥皂泡的关键步骤:在其表面上创建那些复杂的漩涡。欢喜-在此视频中,Mo将阐明建立快速FLIP模拟所需的内容,从而产生高细节的漩涡。
