The model has some bulk areas that their thickness is much larger than others.
In the solaris view, these areas appears to be black. No matter how I tweak the setting in karma rendering node....refraction limit, reflection limit, depth, ray bias, change hdr img......it won't change a bit.

you forgot to lock the geo or include .abc
however I suspect you likely need to enable Internal Reflection

No. Enable the "Enable Internal Reflection" in node "Render Geometry Settings" does not solve the problem.
The internal reflections should eventually tend to black since the material has absorption. If you've already set ray limits to 1000+ then what you're seeing is probably accurate.
tried that, it doesn't change a bit.
thanks for reply.

Ahhhh... little confused? You have an ABC file loading. Now maybe the ABC file was created procedurally, but the *.abc is not included with the hipnc.
reupload the abc file.
The geometry is missing a bottom. This open face lets light escape and energy is lost. Capping the bottom and setting the ray limit really high results in a fully lit bottle for me. There is still a small amount of energy loss, but there would be in reality anyway.

Thanks for reply, but your picture is pure white.
The geo is crop from part of the product. The product geo is full capped. They both have the same issue.

In a lossless renderer, the white furnace test would produce a pure white image. The image has faint dark areas though, so there is some energy loss, but not the absolute black areas that were there before.

post the full geo then. the problem with this one went away when I capped it.
