Ill take a look. Thanks!

Most of the settings on the scene provided were just kind of tossed on regarding refraction and such. I'm sure Ill have some Qs in a few minutes here!

So I'm struggling here.

I have completely recreated a new scene, very simple.

Still running into this issue, flipping normals, doing all kinds of things. See attached screen shots. I am clearly doing something wrong here but I have no idea what.

Whenever I flip the normals it looks like it might be right, but then I apply my displacement and realize it's only working because the back of the condensation object is facing the camera now (displacement pushes the drops into the bottle)


------ Also I included two different objects because I made the first bottle shape using my normal methods of layering edit polys, shelling, etc, thinking that might be the issues. The other basic cylinder shape was made using none of that (except the liquid inside) and still having same issue -------

1) Opaque Materials (glass and liquid inside) have different IOR because they need to, but when I turn one or the other off the effect from my masked condensation still persists.

2) Liquid doesn't use volumetric scattering, when I apply some to it the effect persists.

3) I am using but a 255 white/0 Black colored TIFF as well as the same White/Black alpha map, I have changed some of the settings on channel outputs for the corona bitmap to no avail. I have applied color correct and cranked values, nothing helps.

4) As in my last reply the condensation is as you described, separate object with a material/displacement on it. I have turned off shadows, and a ton of other settings in the object properties as an experiment and still it looks like this...

Thanks for the reply!

The screen shot you have is exactly as I have the material set up. It is a separate mesh on top of the bottle (see third screen shot). I will check on some of the things you mentioned and report back though.

Also, it looks great in the material preview and when it is alone, but the moment it is sitting above my bottle the refraction of the bottle goes crazy, doesnt even need to be touching the bottle to effect it (again see screen shot 3 for best explanation of this effect).

Hi all,

So this is an issue I have been plagued with for years.

Whenever I try to take the approach of using a masked out displacement (or even bump) for my condensation on a glass bottle, it completely destroys my refraction and reflections on the bottle itself. I use a 100% black and white opacity mask to create the areas, and a similar displacement or bump. This works on solid objects okay but is absolutely useless on glass and I do not understand why.

As you'll see in the screen shots provided when the mesh object with the displacement is over/above the glass the underlying glass object renders awfully, no idea. When I move the object away from the bottle you can see the difference between the two. I have spent time adjusting some of the refraction depth and such but the default settings are already so high this does nothing.

Please any help would be appreciated.
