Fake Glossy Refraction?

[meanadam]

I am struggling to make an interior hallway render with white translucent doors.... I can't show you anything cause nothing has rendered....

I have a vray material with a refraction value of 200 and glossiness of .7

I have tried to crank down the settings to the lowest possible, and I still can't finish a LC calculation (at 1/4 final res)!

Using interpolation now @ -5,-4 .5,.5, 10 samples...QMC, etc...

What else can I do?

Oh - I unchecked the fog options, which seems to speed it up a little bit...

make sure the glass isnt generating GI that will speed up the lighting calc.
the other thing you can do is not use a glossy value and have the refraction colour a mid-dark grey

Turning off the GI made it much darker, almost black, and more opaque.

just make sure your turning off generate only you still want it to recieve

Did. Didn't work.
I kept messing with the settings, in no particluar order.

Finally I modified the geo to be a single plane - I don't think this looks as good but is way faster.

The interpolation didn't effect the time as much as i thought. About 5 mins on a 30 min render. Now at -3,-2, .4, .2, 25 samples, and looking pretty good.

I did turn the refraction value up to about 240 - and a little more blurry.

Still slow, but I can live with it.

Maybe the "double-sided" option is on?

Try switching that one off leaving the door as a "box" and see if it gets any quicker...

I'm sure it impacts rendertimes when fog/translucency is on, not sure for plain glossyness...
