不用VEX制作弹跳的丝带No VEX Houdini Tutorial: Dancing Mocap Trails

Houdini without using VEX? It is possible. Although Mo doesn’t enjoy it, he guides you through setting up a simple abstract mocap animation using nothing but built in SOPs. No scripting in this one. Promised.

Of course everything is heavily inspired by Method Studio’s seminal 2016 AICP Sponsor Reel: https://vimeo.com/169599296

For a scene fully set up and lit to render in Octane, have a look at the scene files.

不使用VEX的Houdini？这是可能的。尽管 Mo 不喜欢它，但他会引导您使用内置 SOP 设置简单的抽象动作捕捉动画。这一项没有脚本。答应了。

当然，一切都受到 Method Studio 开创性的 2016 AICP 赞助商卷轴的极大启发：https://vimeo.com/169599296
