I was able to follow along with this tutorial until I wanted to cache and view the results.
I had a very odd problem when I cached the simulation. The cached files are about 20% the size (not file size, but viewport size) of the viewport when compared to the RS renderview. They were the same while not cached, but the moment after creating the cache, the RS renderview shows the exact simulation, but it is 1/5 the size.
Here are my project files:
Here is a screenshot of the difference RS Renderview/Viewport:
I am still not able to wrap my head around the vast visual changes to Pyro in C4D 2023.2.2. The pyro appears completely different, and I believe it has something to do with the changes to the Noise section in Pyro. I was able to alter some settings to begin to get the same wispy nature of Noseman, rather than the blockiness of the 2023.2.2 system.

I posted this on the tutorial questions page, but got no response in 12 days. I assume it is because caching the render is not a part of the tutorial so I need to post in the QA forum.
