I'm brand new to Houdini and have been working on a "shockwave" effect and I have just looked in the Render View and there was only black screen. Then I tried to actually render it but it would still only show a black screen.
I've attached some images below to show the issues that I'm having.
This is my Network inside of a Geometry.
This is how it looks inside Scene View.
This is how it looks in the Render / Render View.
Here's the project file. Please help me out if you can
