Do I need to use ray switch material for glass still ?

[Yousef13]

Hello

I have seen some old tutorials explaining how to use corona ray switch material for glass for faster rendering, I tried rendering with and without RSM and the result are pretty much the same.
I was wondering if it is still needed or not ?
Also, I have tulle material, that actually slows up the interactive a little so I was wondering if I can use ray switch material with it?

Thank you

It's up to you. If you see that rayswitcher isn't really helping with render time, like in case with simple window glass, then it's probably not worth the effort to setup it. On the other hand, on complex material, like tulle, rayswitch may significantly improve render performance and it's definitely worth considering to use it in your scene.
