Mitsuba renderer

[StompinTom]

Veach MLT - 10min render - only source of light is indirect lighting through windows and geometry seams
No exit portals or anything here

Wanted to see how many samples to reach a clean shadows with Veach MLT
8192 samples here - 30 min render

Cool! How are you exporting scenes to Mitsuba? Only found the older exporter and haven't tested it yet... Does it work?

I'm just importing OBJ scenes, it will also load DAE and another format
And I guess you can edit the saved XML scene files, after importing, like old schoool Indigo

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 heavy test with complex Interiorscenes yet ?

Kind regards
Alain

You might be better off exporting Collada 1.4 .DAE file format
But there is a Blender exporter of sorts done by someone. Mitsuba will convert it to the new scene format if it's old in any case.

I don't know Blender well enough to get it to work, where to put it, which of the million versions of Blender to use etc etc

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
Manifold Perturbation is like magic for this, Indigo needs this!

I've done this scene in Indigo and Luxrender and it's pretty slow. 2 objects sitting in water
15-20mins in Mitsuba

Blender Mitsuba exporter has been updated!
