There is an asset on the asset store likely selling this source, without attribution

See the link here:

if you take a look at the package contents you will see the exact same file names.
Feel free to close this issue. I just wanted to let you know, in case you want to go against it.

Hey, thanks a lot for the heads up !

I had no idea but it is true, by looking at the file names it seems that the main effort the creator made is to make the demo scenes and documentation, although without having a look at the file contents we can't know for sure.

Since this has been under the MIT license since its release (a bit more than two years ago) that is totally legit, as long as attribution to this work is still recognized, although I am unsure on how to check that without buying it, as I do not see any mention in the visible descriptions or online documentation.

In any case, I will leave this pinned for now. The pricing looks abusive considering there are better paid (& cheaper) solutions which deal with modernized techniques (compute & froxels with transparency integration) and if there isn't any real addition there is no reason to pay instead of using this package.
