cost to value ratio
I am biased on my cost to value ratio here, as I got Aura 2 in a bundle. For the list price, it is a bit expensive as just eye candy, but it is AAA level eye candy. With that said, considering the developer hours need to make this quality of a volumetric light for your game, this one is a steal.
completeness (asset, screenshots, docs, tutorial, support, forums, chat, community)
Docs are both linked from the asset store and included in the asset download. Support is offered on forum and in discord, as well as email. Didn't dig too much into community, as this asset isn't that complex to need to discuss that much.
does what it says on the tin?
This asset is clear about what it is and what it does from the name to the screenshot and videos.
ease of use / integration / good UX for developer
support + response time
updates and support in asset store (most recent update + changelog, last 3 most recent updates dates)
I would give them a 5+ since the developer actually has been updating the Metal and Vulcan support as I've been writing this article. With version 2 comming out in Feb of this year, and ~ 9 releases since then,
support across the spectrum of unity versions
With no support (yet) for HDPR, SRP, LWRP, or URP and just early support for Mac and Linux, this is the only weakness I can find in the asset. With update 2.1.2, the developer is adding more support already, so by the next update of this review, I imagine I'll get to bump the score up.
Quality (cleanliness / folder structure, etc) of Asset when imported)
Docs both for the API and how to use the package are where you'd expect them to be. Examples were easy to find, load, and use. All of the "meat" of this package
