The PBR Shader was originally included with the product by virtue of the demonstration scene that came with EMC which included my Titan Space Hauler model, and v1.0 of my PBR Uber-Shader. I've since released a couple updates to the EMC Add-on and chosen to update the PBR Shader as well, out of appreciation for current product owners. The EMC Add-on was never intended to be a source for the latest version of the PBR Shader, as that is developed separately. It has, however, come to my attention that a several customers appreciated the addition and looked forward to updates including those that include the PBR Shader. You can most easily contact me on Twitter @BlackhartFilms, and if there is sufficient demand, I can make available a discount code for current EMC owners to purchase the PBR Shader standalone where you will have access to the latest versions of the shader as they are made available. In the meantime, I have a few ideas for the future of EMC and extra functionality for professional and casual users alike, though I must consult with my collaborator about including those in the future. Thank you to everyone who has supported the product, I hope it has been useful, and I apologise for any confusion or inconvenience this may have caused.
