The Bedroom is a typical interior scene with a mix of textured glossy and diffuse materials that is easy to render for a unidirectional path tracer due to large light sources; the windows are actually diffuse area emitters. Since most light transport is governed by diffuse materials, radiance-based guiding techniques generally improve over unidirectional path tracing. However, highly glossy materials such as the ceiling lights made out of rough glass look significantly worse when rendered using radiance-based path guiding. This issue is addressed and noise improved overall by stepping up to product-based guiding. Primary-sample-space path-sampling techniques offer little to no benefit over unidirectional path tracing with our NPS slightly outperforming PSSPG [Guo et al. 2018].
