Houdini制作黑洞（Mantra/Redshift）Houdini Black Hole
The problem with the previous mantra setup (vimeo.com/333709972) is that it was really slow to render, and now with the redshift version it’s supper fast, it has the same features with additionally:
-The center of the dust circle moves faster than the outer ring (more logical).
-Volume (vdb) cloud in addition to the points in the circle.
-Star field (point cloud), to give some depth to the scene.

谷歌翻译：以前的口头禅设置（vimeo.com/333709972）的问题在于渲染速度非常慢，现在使用红移版本它的速度很快，它具有相同的功能：
– 尘埃圈的中心比外圈移动得更快（更合乎逻辑）。
-Volume（vdb）云除了圆圈中的点。
-Star场（点云），给场景一些深度。
