does advanced rendering plugin work on sweet home 3d v.3.1 that i using now?

Yes, there was a small bug that prevented it to work correctly under version 3.0, but I fixed that in version 3.1. But you'll probably get slightly different images if you use it with version 2.6, 3.1 and 3.2 of Sweet Home 3D.

If you want a total control on lighting, don't check Add ceiling lights option. Ceiling lights power depends on the area of the room. It works well in many cases, but you have a better control on lights if you add your own light sources.
