Hi,

If anyone can help.

I noticed that objects within transparent material will render out blur.
Im refering more to the object edges appearing blur (pointed in red arrows). Is there any settings that i can use or set to prevent this? Im rendering them huge, almost 9000 pixels so they are very obvious. The rest (Outside the transparent material) appear alright, in sharpness (with proper DOF set).

Product A: The cap (Transparent material) is very thin so i doubt is the thickness that is affecting. I tried different transparent materials but the inner object rendered out to be same, blur.

Product B: The object (Transparent material) outside is much thicker, if is the thickness that affects it then this will be much blurer that the above object but is not. Again i tried different materials but the inner object rendered out blur as well.

huh?

Sorry. Inshort, everything is sharp. But only the object inside an object that has transparent material is blur. Maybe with this alpha will be obvious. See the edges, is blur out. I will prefer all to be sharp, is it possible?
When i remove the cap, the object will be rendered sharp. (See below the the one without cap, edges are sharp)
Compare it with the one with cap on.

What's the roughness on the transparent material?

Hi Mihai,

Roughness is zero.

I tried using all kind of textures, ranging from manual settings of water to glass to IOR for testing.
In the end IOR (Glass 7059) was used with roughness "0" as it gave the best render in terms of textures feel.
But all have the inner part of the objects rendered out pretty blur.

I thought might be the thickness of the transparent object that makes some kind of refractions around thus blur,
but no mater how thin i adjust it, is still blur.

Regards.
