Greetings to the forum members, I work with glass materials, and there are some problems with them. There are problems on different rendering engines. On Eevee, the glass material does not work in corner, and on Cycles there are problems with the display. Screenshots below. On the image render, the problems are still the same. I will be grateful if you help.
Edit: Thanks everyone, solution: "In Eevee you need to enable the Render > Screen Space Reflections > Refraction option, and the Material > Settings > Screen Space Refraction"
