when creating the bottle, I assigned the rafraction material. added a liquid inside the bottle, everything is fine with the opacue material, but when assigning a refraction material, the liquid is not visible inside the bottle. Previously, this method worked, maybe something has changed in the display settings?
It’s a limitation of real-time refraction. Subsurface and opaque liquid will work fine. Or leave the liquid refractive and set the glass to blending or dithering with highly refllective/metallic material
I find the solution. In settings turn on two sided and inverse culling
Yes, but you loose the liquid transparency and from some angles the liquid disappears.
