Shader looks great, tho the normal on the top seems almost invisible. I really like this tho, I think I can use something similar for a jade statue. But I do think on top of this having a few pieces of geo inside your ice to create the look of cracks that light up at the right viewing angle would be a great touch. 1 last thing and this is more nit picky then anything id say the layer of cracks that seems to be a copy of the top layer beneath maybe just for that layer use your fernsel inverted as a opacity to make them disappear towards the edge of your geo. as for the geo cracks im talking like this, however this is a crystal rock mind you I think youll get my point https://www.google.com/imgres?imgurl=http%3A%2F%2Fspiritwalkministry.com%2Fyahoo_site_admin2%2Fassets%2Fimages%2Fcs_2.219164821_std.jpg&imgrefurl=http%3A%2F%2Fspiritwalkministry.com%2Fcrystals_and_stones&docid=lk6sDMKahaB8eM&tbnid=NXOT-rV4vumsGM%3A&vet=1&w=224&h=224&bih=642&biw=1280&ved=0ahUKEwiLkfK-96TcAhWRJXwKHSErBXEQMwh1KA4wDg&iact=c&ictx=1
In this tutorial jaynam is comparing the way post-processing effects can be used in Unreal Engine 4 and Unity 5.6. He mentioned in his previous comparison of these game engines that UE4 offers more flexibility with the concept of Post Process Volumes than Unity does, in this videos he goes more into detail about this topic.
First he shows a scene in Unity 5.6. without any Post Process Effects assigned. In order to use the Post Processing Stack, which he recommends over single image effect scripts, the user has to download an asset from the Unity Assetstore.
After he downloaded and imported it to Unity, he adds a new Post Process Behavior script to the camera, creates a Post Processing Profile and adds it to the Profile property of the script.
Now the effects can be set for the profile. The Post Processing Stack is a great feature in the opinion of the author but it has to be attached to a camera and has therefore a global scope for the scene.
In Unreal Engine Post Processing can be set by so called Post Process Volumes. Jayanam opens a Unreal Engine 4 project in which a Post Process Volume is added to the level. It has the property called “Unbound” set to true, that indicates that all effects that can be set for the Post Process Volume – which is actually a transformable box – will affect the whole level.
After that he unchecks the property and demonstrates how the Post Processing is applied for the boundaries of the volume only when the camera is inside of these. He also uses the fading-in and -out of the effects by setting the Blending radius property.
More volumes can also be added to the scene. The author points out that this concept is in his opinion more flexible than the one of Unity, although he really likes using the Post Processing Stack of Unity 5.
