Houdini油漆飞溅教程Houdini Paint Splash Tutorial

In this tutorial I’ll show how to create paint splashes that are easy to control with custom velocity fields generated by simple curves.

As usual the file is available on Gumroad. I’ve commented the file, extended the functionality of the velocity field system (adding the ability to paint areas of higher force). You’ll also get some insight into the shading and rendering from the file.

Also at the end of the video there’s a preview of my next video where I’ll show how to take this set up even further using some more advanced techniques using help I found on forums and using some tools that a couple fantastic Houdini users have created.

在本教程中，我将展示如何创建由简单曲线生成的自定义速度场易于控制的油漆飞溅。

像往常一样，该文件在Gumroad上可用。我评论了该文件，扩展了速度场系统的功能（增加了绘制更大力区域的功能）。您还将对文件的阴影和渲染有一些了解。

在视频的结尾，还有我的下一个视频的预览，我将展示如何使用一些更高级的技术，在论坛上找到的帮助以及一些出色的Houdini用户创建的工具来进一步进行此设置。
