When trying to build cubemaps, and error appears:

Code:
Cube map buffer size 2048 x 2048 is bigger than screen!
Run at a higher resolution! or reduce your cubemap resolution (needs 4X)

Problem is, highes resolution available to me is 1920x1080, and even Nvidia's DSR doesn't seem to change anything

Pls help

Why can't you just reduce the cubemap size? 2048x2048 is incredibly high for normal purposes; the default is 32x32 for a reason. What are you generating reflections for that you need reflections of a higher resolution than most players' screens?

All cubemap sizes are set to default

Do you have very big brushes in the map? Sometimes they can cause issues like this if the surface is too big. Check also alt+p for errors.

Are you running a quality graphics config? I know a handful of em like to change mat_envmapsize despite the fact I believe it's only used for the cubemap buffer when building them. Go ahead and set that to 128 if it's set to anything else.

[SOLVED] Setting mat_envmapsize and mat_envmaptgasize to 128 fixed the error.
