Hi again,

I guess your still much busy but if could just take a look on some error that occured
while exporting to Mitsuba:

http://www.pasteall.org/pic/94792
OR
[TriMesh] Encountered an invalid format !

Ive noticed its somehow mentioned earlier BUT..I used just PNG texture and thats the only texture in the model so far. PNG incl. transparency (its a metal mesh texture w/alpha).

no idea why it happens but it happens.
it kill my arch.work at the moment (((

cheers,

bcd

This is great, thank you !
Are you a programmer - if not-where did you learn Ruby?
May other develope your code?

cheers,

Thank you, Tah2Hata !
Now I got a chance to finish my work ! )))
A question: while render is active there are Render settings on Mitsuba's window - such parameters as Reconstruction, Sampler, IR, Adaptive cache etc etc.
They work condtionally and are related to each other, also specific materials require specific integrators (eg. SSS) - these options(and possible error) are shown ONLY on Mitsuba's Settings window and NOT in your Exporter, could they be duplicated&adjusted from within Exporter also-so one could choose right render mode according to materials and other parameters (and potential discrepancies could be signalised prior to render start?) ?

There must have also been a bug related to Sky scale: setting values exceeding ca. 3.9 causes error.

Additinal question: I have noticed clearly visible, sharp, shattered shadow edges from the Point Lights , Sample count does not seem to correct the issue - you have any idea about it?

Is DOF missing from latest Exporter or am I wrong??

;;;

Could the rendering process be somehow GPU-accelerated by eg. CUDA (on Nvidia cards or OpenCL on AMD) ?

Thank you for your response!
Above a scene from my latest work/early Christian church/ I got to finish until Tuesday, but MItsuba exporter refused to cooperate-I described in previous post along w/ Ruby console.
Just happens nothing after pressing EXPORT and a while of 'hesitation'...(((

Is there a chance the error is recogniazble and could be corrected soon?

cheers,

UPDATE to previous post w/Ruby console output included:
I have partly figured out the problem source:
I started to adjust Sketchup materials w/Mitsuba editor.
One of the textures had a bump map added - after clearing material in Mitsuba Editor all was happily OK )))

For further consideration/correction/error handling ?

And another very annoying error: after a few tries ,when I push EXPORT it holds for a while,
then releases and ...nothing happens: (AMD Phenom X4)

Wll, for me its great news and support for present work, I got a few questions to you though:

1. Is/would light temperature be supported? (Spectra Lighting) ?
2. Volumetrics?
3. Antialiasing (how to adjust) ?
4. Pls help w/some hint to fully understand and make use of the settings in Your Exporter 0 I am NOT a novice in CG/Viz but many of the parameters are not so obvious still..)))
5. UI would need some organizing-I am open to help in any way(graphics?), personally I'd suggest a vertical windows like VRay's or CleanUp3 plugin?
   How could one help you to polis/develope this great work (I am not a programmer unfrotunately ((

cheers,

Yeaahhh ! great-seems I needed to reopen SKetchup, thank you !

BTW: is lightbulb effect for s point light still present?

Still some error:

Hello!

Its may first post on Skechucation sohello to everyone and special thanks to Tak2hata
for Mitsuba interface, its great idea&job ! /I hope you keep on developing it still )))

Lately I tried to use Mitsuba w/Skecthup for my work but it ran unpredicatbly - once was OK, the other time it stopped importing scene, below one of the examples of failure:
