Scene shared. Thank you.

I got them sort of fixed by changing the color of the liquid to near white, then just photoshopped the color back into the liquid. :wtf: :)

Thea Knowledge-Base - Rendering Liquid in Glass

I have assigned proper Containers to the bottle parts and it renders without this peculiar reflection.

It is also possible to have very detailed group/component say 100x larger and then scale the group down to 0.01 to get real physical size. It will be safer from refractive materials perspective, as they would have real-life values, instead being tweaked to match. There rendering shown below still uses the original very large size. I didn't change it, but it may be worth exploring.

Thanks Tomasz - I'm sure you're right about the containers helping and for sure, the color of the liquid was to match a photo that I found out the client had tweaked very unrealistically in photoshop, the real liquid color is much more reasonable.

I appreciate you for taking the time to find the error. :clap:

The reflection still appears to be odd somehow. But it turns out the client requested that I just flip a copy of the bottle upside down and under the original bottle, so that the "reflection" is able to be masked by object, reflections, etc. So these caustics turned out to be a non-issue. :|
