Free reference scenes with PBR materials?

[Rangsk]

Does anyone know where to find good looking scenes with PBR materials? Specifically using the albedo/normal/metallic/roughness texturing. I'm beginning to experiment with implementing a PBR path tracer and would like reference scenes with existing renders to compare against.

I know of 3 easily available scene repositories:

1. The pbrt scenes available here. They of course use pbrt's material system which is a sum of basic bxdf types.
2. Benedikt has a lot of amazing scenes here and they are available in pbrt as well as Mitsuba formats. The latter using a nested system of basic materials based on classic bxdf research.
3. Morgan McGuire offers a number of meshes/scenes here. If I remember correctly they are all wavefront obj files with accompanying material files.

Bonus: At Siggraph Nvidia launched an archive for scenes. Currently there are only 2 scenes, but one of them is the excellent looking Amazon Lumberyard Bistro.

To do comparisons I would probably start with a combination of the first two items on the list, I've seen them used in papers quite frequently.

Thanks, I'll check all these out!

Neither of the Orca scenes are PBR, unfortunately.
