    hello,

    i'm sorry for this rather basic question, but I'm in a bit of a rush. i'm going to be building an online app for architecture purposes. for this architectural application, it will be required that the application can calculate a radiosity solution on user demand. tell me, can the unity player be made to calculate radiosity lighting solutions?

    thank you!

    Short answer: no.

    thanks. so I'm assuming the only way to get a radiosity solution into unity player is to bake it into the textures in your favorite 3d program before importing to unity. I guess that's what this guy did.

    Yeah. Typically radiosity is stupendously calculation-intensive, so it's not really possible to do it properly in real-time at the moment.

    Actually, it is possible to calculate whatever lighting you want yourself. Calculate radiosity (e.g. a bunch of raycasts or whatever else), put that into a texture or vertex colors.

    Of course, most radiosity calculation methods are not fast. So if the question is "is that possible" - the answer is "yes". If the question is "will it be fast" - probably "no".

    well, I just want to make sure I'm being clear: I don't want unity player to calculate radiosity in real time. What I'm looking for is to allow the user to build a simple room (say a kitchen) in my application and then, when they're ready, press a "calculate radiosity solution" button that will calculate radiosity. If this takes some time to put out the solution that is fine. From what I'm hearing here, this is possible?

    Thanks so much for your responses. Again, sorry for the simplicity of the questions. Once I really read up on the platform I can make more informed questions. But I just need to get a few basic questions out of the way first.

    Yes, that is possible. Of course you'd have to implement the radiosity calculation yourself; at the moment Unity does not have builtin functionality for this.
