Hello everyone,

i've been having a super cool time watching Tu Wien rendering lectures on youtube,
https://www.youtube.com/watch?v=RuBjYa4Q3dA [www.youtube.com]
i've been impressed by the bidirectional path tracing computation
because i'm facing this scene lightning scenario a lot, and i'm wondering :

Is bidirectional pathtracing available in Mantra ?

If we create an indirect light will it converge like bidirectional ?
i'm not into render engines but there are caustics and photons involved with this node

… and will i got into the SDS conflict case scenario or does the PBR mantra rop protects from it ?


Thank you for your feedback

no, Mantra doesn't do bi-directional pathtracing

you may want to try Renderman, it has couple of integrators that do that like PxrUnified and PxrVCM

Thanks a lot Tomas for your answer,
i will try those integrators you mentioned,
cheers, ++
