My questions

[SHD]

I put the glass in the scene, but rendering is slow. May have any tricks?

[lacilaci]

make glass a plane (1 face) and make material twosided instead solid glass.

and there is now, plane with 1 face with glass twoside material

[SHD]

any ideas?

How about sharing the scene? May be without furniture.

[Dom74]

this is normal, the computation time increases with the glass, because of the bounce and the light that passes through the glass, nothing abnormal.

[maru]

Looks like something is really wrong with thin glass. I thought it's reflection caustics, but not much changed after disabling reflections for the glass shader. I bet this is already known and will be fixed soon (or already is).

render time: 1min

glass - scene with glass geometry
noglass - scene without glass geometry
glass-norefl - reflections disabled for glass geometry

[SHD]

yes, even strange with dof

[SHD]

what about caustic?

[maru]

As far as I know caustics don't work with Corona's sun. Yet.

THey do, you only have to increase max sample intensity (and then you discover that you get bunch of fireflies in place of caustics, and use bidir ;))

Unfortunately I do not have a version with bidir..
I think soon completed yet fully interior design office in Corona, looks great, but sometimes there are problems in rendering errors and ..

[Ondra]

I hope to release next alpha that will include bidir soon (in 1-2 months)

currently ConstantMTL is not work ?

currently ConstantMTL is work ?

I have very quickly tested it and it seems to be working properly. Is it not working for you in Alpha 4 RC build?

i try in build from 12 march, rendering is fine, but options do not affect (for example - Multiplier )
some later i try in A4

[Ludvik Koutny]

Weird, for me, multiplier works :) Give A4 RC version a try, and if it still does not work, then let us know. That's kind of bug A4 should not be released with ;)

[SHD]

Thanks, now  is working well
