solid glass object looking like two surfaces
hello,
i created a bottle in cinema4d r11 as a hypernurbs object and gave it a standard glass material. as you can see in the following image the glass object looks like there were two surfaces, an inner and an outer one. it does not look like one solid object, although it is modeled as a single object. looking at a real bottle i am not able to see the thickness of the glass but in my rendering (lighting is hdri + area lights) i can see it. what can i do to make it appear as a solid glass object?
here’s the image: https://w00b26ac.dd5434.kasserver.com/bottle.jpg
thanks for your advice.

My suggestion is turn on the reflection channel if it isn’t already and put the fresnel shader in there. That should take care of it.
Unrelated, but if you’re using speculars you should also activate the specular color channel and put the effect>normal direction shader in there. That will prevent specular highlights from showing up on the inside surfaces of your glass.

That is nice tip. I have struggled with that in the past.
