I created an astronaut floating in space, he's working fine. Then, in a separate .blend project, I created a galaxy to float behind the astronaut. I used append to add the galaxy to the astronaut scene. It should be located way behind the astronaut, but I noticed it wasn't rendering at all. It wouldn't even show in the workspace unless I zoom way in.
When I try to render an image, it fails. Can't see the galaxy at all unless I place it directly in front of the camera, but this can't work, since it needs to be in the distance, and even up close, it's not rendering correctly.
This might have to do with Eevee! If I switch to "cycles" it seems to work, but the time it takes to render is not acceptable. I mean, the astronaut is animated and renders a video in a few seconds. The galaxy takes several minutes to produce an image (in cycles mode, that is... in Eevee it doesn't render at all).
Below is an image of the galaxy not rendering in the viewport. If I switched to Cycles you would actually see it.
My question: Is there an Eevee setting that will allow me to render this object? Or is there some other setting I'm getting badly wrong? Maybe the galaxy object's emission that will allow it to be seen at a greater distance? (I already set the camera's clipping distance high and it still doesn't render)
If it helps, here's me switching from Eevee to Cycles and it renders perfectly, but this won't work for me creating multiple clips https://imgur.com/a/IRpcWOM
Another example, I found the vertical plane a few feet behind my astronaut, where Eevee simple stops trying to render. I angled the galaxy so only half of it shows because the rest is just not rendered at all
