Flicker-free splotch issue

[Frood]

Yes, I was refering to hotfix 2.

Would be great to have some kind of automatic detection and automatic fix for this.

Detection would be enough. Atm I find myself resetting scenes + readjusting all the time because I can´t see if a scene is "infested". Any option to find out at least manually?

Good Luck

Any option to find out at least manually?

Look at UHD cache settings, if precision is set to 0.4, there's a good chance that scene is affected by the bug.

Thanks romullus, indeed I noticed that value in some scenes but - corrected it with a shrug and - saved :(

So I deleted the last clue without knowing it. But I will continue to pay attention to this. Well, seems there must be some risk left using dailies in production...

Good Luck

One solution to be always sure that the settings are correct is copying them from a healthy config file (e.g. created in 1.5.2) and pasting it into the string options window for any suspicious scenes:

Code: [Select]

Float gi.uhdcache.precision      = 1
Float gi.uhdcache.precompDensity      = 1
Int gi.uhdcache.interpolationCount      = 5
Int gi.uhdcache.recordQuality      = 512
Float gi.uhdcache.normalSensitivity      = 2
Float gi.uhdcache.dirSensitivity      = 3
Float gi.uhdcache.glossThreshold      = 0.9
Float gi.uhdcache.strictness      = 0.075
Float gi.uhdcache.msi      = 3
Bool gi.uhdcache.correlatePrecomp      = true

Ok, if there is no other option I will spam our default startup scene with string options, maybe omitting the precision setting which would override the UI value if there is really no other way to find out.

Good Luck

Sorry, I didn't realize I posted exactly the same thing earlier. :D

What editor do you use to open conf files? My "healthy" conf file from 1.5.2 looks like this :[

[Frood]

It is already fixed, see your own report :)

Any editor capable of handling unix format style (LineFeed only at the end of a line, CarriageReturn "missing") and UFT-8 will do. Notepad unfortunately not.

Good Luck

Yup, this is already fixed and my workaround was to use WorPad. :)

That's what i wanted to know, thanks. It looks like new DB won't be available till december and that messy conf file just driving me mad :]
