This guy has an alternative way of getting the same effect. Might be worth checking out to.

To summarize the video though:

Create a Render Texture (right click in Assets > Create > Render Texture)

Change the size of the Render Texture to 64x64 (or whichever resolution you want)

Apply the texture to your Camera

Create a Raw Image UI element (GameObject > UI > Raw Image)

Resize the Raw Image to fit the whole canvas

Apply the texture to the raw image.

Yep. That's what mine does. It's just set up so that you can drag and drop it. It also is configured to where it scales to resize and keep aspect properly without stretching and such. But it is using that method at it's core.

To the experienced unity dev, this only saves like 10 minutes, but to someone that's newer or just hasn't done anything like this before but is still experienced, it could save several hours.
