Houdini将粒子粘在表面上Houdini sticking particles to surfaces

I played around with sticking particles to moving surfaces by finding the closest position, raying or saving the uv position of the particle.

I then created some noise / direction vectors for the particles to move on the surface to create some different looks.

If you want to have a look or play around with it yourself, you can download the file here:

我通过找到最接近的位置，掠过或保存粒子的紫外位置来玩弄粘附粒子到移动表面。

然后我创建了一些噪声/方向向量，让粒子在表面上移动以创建一些不同的外观。
