Thank you very much for the kind words 
Thank you for the kind words! My system does not use the GPU particle accumulation shown in that video. While it is a great feature and has plenty of practical uses, it doesn’t perform well enough in large, open scenes, and doesn’t pile up as well as using displacement. I had considered using it and the masking function I have now, but it likely still would have performance issues and would essentially be a hat on a hat.
Let me know if you have any further questions!
As of right now I have a post-release updates list on Trello that people can vote on. Following the marketplace release of this system, I’ll begin working on regular updates to start rolling those features in, as well as addressing any bugs/performance issues that are reported to me. Please be sure to vote for the features on that list that you’d like to see, and I’ll address them in the order of most votes received. If you’d like to see something that isn’t on the list, let me know here in this thread, and I’ll review the plausibility of adding it.
I’ll also throw this into an empty scene after work today and give you the most current performance stats.
Cheers!
