If you contact me directly through my support site, I will usually reply within a day or a few hours if I'm at my PC. Screenshots are usually enough for me to figure out what the problem may be. Keeping all my assets tested and updated for every single version of Unity is simply not viable, instead I go by feedback I get from customers and try to solve most issues as they get reported. https://archanor.com/support.html I also have answers to the most common problems on the same site in the FAQ (pink and invisible particles). Usually the answer here is to upgrade to URP and enable Depth Texture in the project. The asset was made (and previewed) in the built-in pipeline, this is why there are some extra steps to get it going with URP. You have less realtime lights available, and also URP does not just render additive materials very well for some reason. I'm not sure, but switching between deferred and forward rendering could solve this visual problem if the pipeline supports it yet. In some cases there can be some severe bugs with the latest Unity version, so I recommend that you use the latest available LTS version. Edit (25. aug): I don't get notifications anywhere when reviews are updated which is why I recommend that you use the proper support channels. If you are using 2D URP you will simply have to disable the Soft Particles setting on the materials. It would be good to know which version of the editor you are using so I can test/reproduce in case anything else is wrong. I also want to explain here that in the Standard/Built-in render pipeline particles are showing up normally when Soft Particles is enabled, but in URP (to everyone's confusion) they are just invisible if the Depth Texture setting is disabled. I think this may be fixed in later versions of URP. They will also not render when there's no depth (e.g. if you are using an isometric camera), which means they might be invisible for the 2D template. Kenneth F. Moe
