I have rebuilt Valkaari's HOT4D plugin for R20 through to S24 on both OSX and Windows. All the plugins and installers are correctly notarized with Apple so there will be no installation issues on OSX.
This is not a free plugin. I have to cover my costs.

Should also work on the new Apple M1 chips in S24. I haven't tested since I do not own one.
All of Bob Walmsley's videos appear to map well to this new version. You can see all his videos on my website as well.
Here are two examples of scenes created with the R16 version of this plugin.
