[solved]inexplicable noise in every scene

[fLuppster]

Hi, i started an interior scene and since today im having inexplicable noise.
So i tested everything in a new scene, and suddenly there was noise too...

An Interior normally should not take this long:



Even the testscene is bugging.


You can have a look at the testscene.

I set up everyhing as usual and i have no clue, why since today it is bugging.
I already installed an older corona version, its still not working.

Can you help me please? Unfortunately it is very urgent.

do not have cinema, but thinks it hdri\enviroment problem, it is too bright, try to lower intensity and set higher exposure in corona settings

This worked:

-cap the window with a plane with portal material assigned
-add thickness to the floor (cap the geometry)
-increase filter size in render settings to 2

Scene like this requires a portal ?

[maru]

Apparently it helps. The difference is insignificant though.

[fLuppster]

Thank you guys. Yes, i thought scenes like this do not require portals. But it seems, it still helps a bit.

[romullus]

But what was the main issue? Don't tell me it's filter size :] Does capping the floor alone, had helpped to get rid of most of the noise?

[maru]

I did all the things mentioned, but I think it was the portal.

[Juraj]

Well, that isn't 'insignificant' now is it though :- ) ?

I always find corona portals bit unpredictible. Maybe thats my ignorance (shame). I always give a try to test what is the best for different scenes.

Adding window with frames might change things a alot in such situation (unless you place divided portals) :)

yep, I am not satisfied with portals and environment light sampling in general. That is why we will improve it in 1.5. There is IMHO a lot of speed to gain.
