Why is My Render Black?

Every time I run into a situation where a Render TOP is black or all 0 0 0 0, … well I decided to write down the procedure for once.

Any other things you have had to check in the past?

Here is something that happened to me more than once by accident.

In your window output, it’s possible to resize and move your preview. I use a spacemouse, which outputs both joystick data and mouse wheel scroll. So I ended up changing the scale of my output down to zero by mistake. I fix it by pressing “h” but it took me a while to figure out what happened the first time.
