Window frame and use of Portals

[Torsten]

Hi guys,

I am constructing a scene with a large windowframe next to a courtyard (see attachment). Now i am wondering what kind of portal setup i should use? Should i give each individual glass window its own portal? or should i create one portal for the total surface? Another question, rendering wise, is should i model each window glass itself (multiple small glass objects), or is one glass object just as sufficient?

That's a fairly large window, You don't need any portals here.

Thanks for the quick response!

Ha, and i always thought you should use portals if possible (i checked the corona turotials yesterday). I attached another image. In this scene i think most of the light will be indirect, so i thought this was a typical scene where you can benefit from portals?

I don't know if this is correct. I would place portals like this

Yep, in this particular case, you should place portals exactly as on example from Cheesemsmsm ;)
