POST parameter: bug or incorrect behaviour?

[cecofuli]

Polymax, sorry, but... what's you PC? In 13 minutes, with my i7 970 esacore @ 4.0Ghz I've a lot of noise!
I open your file and hit render...  Also the rendering is darker.
I redo the render in VRay in 30 min.

[Polymax]

I have I7-980 (3,91 GHz).
What version of Corona are you using?
I use daybild from March 25.
Verify the settings:

[cecofuli]

I have the official A4 Mar 18...
I'm not able to use the daybuilt...
Yes, same setting of you.
In attachment after 26 min...  :-(
You use MSI = 10 with Exposure 4.5 . From my test, better to use MSI= 200 or more (for the rendering brightness)
Very strange...

[Polymax]

Ok, I understand your problem! Please set the parameter "Writable for # passes" in the HD cache setting to 1 and try again!
Alpha 4 build have a bug with CameraClip and HD Cache, but now is fixed!

[cecofuli]

O__O what's this parameters?? Now all is perfect...
I read the on line help but... it doesn't help me =)

[Polymax]

Ok,solved! :)
ps: On the forum discussed this issue ;)!

[cecofuli]

Ok, it's the HD cache and Clipping plane problem. Thanks

And.. what about the weird and bad antialiasing problem near the bright part of the ceiling? Remember me the baaad old sub-pixel mapping and clamping problem in VRay. there is a solution?

set internal resolution > 1 and then go up with higlight burn until the aliasing disappears

Ok, I'll try. I'll do more test and I'll post here ;) Thanks

cecofuli, if you still have a 'dancing' with post processing parameters, then you must set post contrast to '1' and don't change it more. In this case even MSI 20 will work properly, but may give some 'dancing' with renders in views when using only nondirect lighting

i hope i wrote all correctly)
