Hi,
We need a “Rick from the future” scene at 14:12 for this lecture - Explosion Particle Effects under the Laser Defender game.
That change rick is doing for Standard to Particle Alpha Blanded does not exist in newer versions of Unity…
From a quick google i saw that it can be reached via Legacy Shaders --> Particles --> its here.
There’s another way to do it but i guess if you want to stay true to the lecture you need to pick the same one.
Hope this helps
