Maxwell Render | Official public forum

Hello,

I want to understand a concept about single or double sided models.
I know that AGS is a double sided solution that could be used on a single sided model.
The new translucent materials as the leafs in the provided library, is also a double sided solution that can be used in a single sided model.
That is all I know, but with all other materials I am lost, and do not know whether to use double or single sided models.
I will be more than happy to understand this.
Yours

The thing to remember is that when you use a material with refraction, light rays are bent, such that it is important how light enters and exits a volume. Say that you had a building with single-thickness window panes. f you applied a real glass material to these panes, light would enter your building, but it would not exit, until it came out of a window on the opposite side of the building. In other words, you would be telling Maxwell that the interior of the building was filled with glass. There is nothing special about AGS, that allows you to use it in this situation; the reason it works is simply that it has reflection, but not refraction. It is not like glass -- it is like a mixture of mirror and vacuum.

Thanks so MUCH JDHill!

Actually JD I've never heard it explained that way. That's very clear, thank you.
