Mixture material (mixturebsdf)
This plugin implements a “mixture” material, which represents linear combinations of multiple BSDF instances. Any surface scattering model in Mitsuba (be it smooth, rough, reflecting, or transmitting) can be mixed with others in thismanner to synthesize newmodels.There is no limit on how many models can be mixed, but their combination weights must be non-negative and sum to a value of one or less to ensure energy balance. When they sum to less than one, the material will absorb a proportional amount of the incident illlumination.
Parameter Type Description
- weights : string
- A comma-separated list of BSDF weights
- (Nested plugin) : bsdf
- Multiple BSDF instances that should be mixed according to the specified weights
