It looks fine in the viewport in but renders distorted/curved.
Here’s the settings for the shader and rendering
![render_1|546x500]
![render_1|546x500]
Maybe try to increase the quality of lumen trancelucency to 2 or 4, increase the bounces, tick the high quality check box.
You can try using raytraced translucency. You may have to activate raytracing in the project settings. Activate lumen hardware raytracing there as well.
Materials have an advanced property option called “forward shading”. It’s good to activate this for glass. And make the glass material two sided.
See if that makes it better
Thanks that helped, looks much better now
Kind regards
