I create some glass material for Eevee. When the camera is close to glasses, then everything is rendered normally enter image description here. But if I move the camera away, then the detail decreases in the glasses. They become low res enter image description hereenter image description here. How to fix that?

  • $\begingroup$ Hello :). I might be just short-sighted, but I cannot see the problem here. Are you sure just increasing the render resolution wouldn't help? $\endgroup$ – Jachym Michal Nov 25 '19 at 14:46

    $\begingroup$ Yes, look at the shelf, it is normally displayed, and the glass is all in pixels. This should not work like that, I hope. $\endgroup$ – Рустам Мукашев Nov 25 '19 at 16:32

Pixelation is visible on any of your glass cup object. Not only on far one from camera. The issue is just more visible on smaller cup than big one. So it has nothing to do with camera distance, but aliasing. Probably cost of eevee speed.

With Glass node IOR to 1 (or above, ussually 1.43 is used) pixelation is gone.

You can try to set Film > Filter Size > 3 in Render Properties. Filter Size cares about aliasing, but in price of loos of sharpness (render became softer). Blender manual.

From top to down 0 / 1.5 / 3
