Happy new year everyone!
ShaderSource has been slow over the last couple of months due to a shutdown for the holidays and working contractually with another company.
Below is a new asset currently in submission process. It is a Volumetric Light Function solution for Point and Spot lights, as currently this is not supported in UE4.
It will be released for $4.99 hopefully within the next month.
Updates for the older assets are still in progress, and hopefully will have some more information to share soon.
