With 1.1.5 i can't see the sky through glass.
This is my glass material:
Code: Select all
<medium>
<name>Medvetrob</name>
<precedence>10</precedence>
<basic>
<ior>1.50000</ior>
<cauchy_b_coeff>0.00000</cauchy_b_coeff>
<absorption_coefficient_spectrum>
<rgb>
<rgb>1 1 1</rgb>
<gamma>1</gamma>
</rgb>
</absorption_coefficient_spectrum>
</basic>
</medium>
<material>
<name>vetrob</name>
<specular>
<internal_medium_name>Medvetrob</internal_medium_name>
<transparent>true</transparent>
</specular>
</material>
With previous version it was visible

Don't use BiDir

Thanks BdB, it works... I'm feeling very stupid

Don't worry. Only reason I know is because I've been there too...

Thanks for saying this, BbB. I can't seem to stop reporting bidir caveats, mainly endless grain, to a point where i'm fearing a ban from unbiased renderers sites
In the case bidir works good for a given scene, but do not allow noise reduction in a decent time frame, I suggest to polish the render by resuming the igi with pure MLT.

*idea* for multiple threads (I said some similarish things before, already...)
each thread has its own rendermode.
With 6 threads, you could have every rendermode running at once!
- MLT BiDir
- MLT
- Hybrid BiDir
- Hybrid
- PT BiDir
- PT
With just two threads, one could do, what you just suggested but in a single render

You mean putting every technique result in a separate layer ? That's just 3 of them mate !

Is that already possible? How do I do this? Do I start it from a command line and type in some funny stuff or something?

Hold on Antony, we are speculating on Ingigo (near) future
Still, you can render the 3 images separately and... well, you know that already

Oh right I knew that. And yea render them seperately good point, I knew that too

Nah, I also mean, splitting bidir and no-bidir in single threads... Then, you have six of them. (If you set all six, that is. - it could easily be that that's suboptimal for most scenes...)
Lol anthony. Well, did you actually save an igi? Then it should be kinda simple
