Re: Mitsuba renderer

Mitsuba was updated again, better .OBJ and .DAE import. I finally got this scene into it, but there are some shading errors I need to sort out :) I hand edited the water in. 12 min or so render! Very quick on the caustics - by far the fastest unbiased renderer in this aspect 8) Manifold Perturbation...

Re: Mitsuba renderer

Ok I export a OBJ-File. But does a OBJ-File also contain the lightsources from my Blenderfile ? And how do I have to setup Materials, Sunlight,... ? Do I have to edit an *.xml file ? BTW: It also supports instancing geometry, see here: http://www.mitsuba-renderer.org/devblog/ Did anyone did some he...

Re: Mitsuba renderer

Veach MLT - direct light sampling off, about 15 mins or so render time Manifold Perturbation option on vs off Turning it on slows down the sample rate, but improves the convergence of the torus and refracted caustics - handy for pool scenes! I also found it better to set number of bounces to -1, inf...

Re: Mitsuba renderer

12 minute renders with the Veach MLT, on my i7 3930k at 4.2ghz system

Very impressive!
That Torus scene is like a pool/caustics scene, very difficult in the standard MLT in Indigo/Luxrender etc

Re: Mitsuba renderer

Mitsuba 0.4 gets two types of MLT among lots of goodies, seems pretty fast too 8) Especially the Veach method. The other simplified one is like Indigo's, which piggy backs Path or Bidirectional path tracing. Tried the Veach MLT method on the Sponza scene and it will hit 1024 samples in 6+ minutes on...

what do you mean by physical diffraction? Non-post-pro?
Because they're both as physical as each other :)

Re: Indigo aperture diffraction vs real life - too weak

I meant the physical diffraction, has this been improved as well?
