We present an extension to Metropolis light transport (MLT) methods that enables the use of unbiased estimates of the contribution function instead of the exact quantity. By approximating the transmittance in heterogeneous media with recent, efficient unbiased estimators, our new method enables significantly faster rendering compared to previous work.
