Fast glass material

[Blitterswitch]

Hi guys,

I am in the final stages of putting a visual together and I am populating a servery with glassware. I am having a really hard time creating a realistic but fast to render material.

I was hoping somebody could offer some advice.


Thanks,
Marcus.

Maximum refraction, falloff in reflection, affect shadows turned on. Make sure its got a thickness of between 5 and 10mm and a good environment, and youre good to go.

I'd put a slight bluey/green tint to the fog too, but depending on the thickness of your glass or scene scale you'll need to mess about with some numbers.

Mine is always :



Anyway, I'm not sure that the "avoid 255" rule does apply for this type of material...

If it's totally clear glass then turn it off to gi too.

very clever, never tought about it

but... turning emit GI off or receive GI off ? or both ?

[Neilg]

Both, make it completley invisible to it.

It's strange, I've just made a quick test and wrapping the glass mat has the same effect has unchecking "affect shadows"

When changing GI attributes in the object's Vray properties, it works ...
