Hi, found very nice looking vfx while reading this article - https://unity3d.com/unity/whats-new/unity-2017.1.0
Graphics: Added Custom Render Texture asset. A Custom Render Texture is a new type of Render Texture that can be easily updated with a shader. It provides a user interface and a scripting framework.
And I have a few questions about it. First of all, how it was created? I was trying to create something similar with Shader Forge but failed. Can you give me some clues?
And a second question, how exactly Custom Render Texture involved in this effect?
