Hyperspace is broken

[cu-kai]

The hyperspace animation (shown when teleporting) is broken. This is shown by reproducing the following bug: https://github.com/Unvanquished/Unvanquished/issues/2447

However you can see it briefly when using any normal teleporter. I do not know what the "hyperspace" animation should look like exactly.

The original quake 3 code does the same thing: https://github.com/id-Software/Quake-III-Arena/blob/dbe4ddb10315479fc00086f08e25d968b4b43c49/code/renderer/tr_backend.c#L397. Although the result might be different for one reason or another.

I think it is not visible because RDF_NOWORLDMODEL causes the camera effects shader to be skipped. But the camera effects shader is actually critical to render anything at all because it is needed to copy data from the "main FBOs" (where most rendering is done) to the final draw buffer. So what you actually see is just the last two frames before entering hyperspace, toggled back and forth until you get out.
