I rendered this in Yafray. Default settings except exposure is turned up to 8.
The bottom of the bottle is casting way too dark of a shadow. I’m not sure how to fix this.
When the bottle is not so close the floor, it looks fine.
Does anyone know how to fill the bottle with a liquid? I can’t wrap my head around how to go about it. I can imagine making a mesh for the liquid, but how to place it inside the bottle without breaking the bounds of the bottle mesh, and without leaving a gap between the two meshes.
