Indigo Renderer Forum

I'm reading that MLT based renderers have issue with caustics behind dielectrics. What's the deal with that?? Can Indigo do those??

Thanks,

yes it can, since some time, now.
There already was a HUGE test-thread, which showed the problem and went on, when the problem was solved and much more recently, there was a test, again
You just need to make sure, that your Max_num_consec_rejections (a render-setting, found in the inifile and in theory also in your exporter's gui) is at at least 1000 - then, you should see caustics through transparent stuff

Or you don't use bidir and wait some more...

Thanks for reply guys..
I was at NextLimit forum and some people bitched about not being able to see caustics behind transperent stuff. Someone said that is common for MLT renderers. I was sure though that indigo can do that..

as I said, it can, but not since too long

as long as you have bidrectional on and MLT with MNCR at least 1000 then you will see them given enough rendering time

Maxwell is just Path tracing, no MLT there, so you will never see caustics behind glass ever

need MLT for that

" ... need MLT for that"

That's the point!


take care
