regarding edward's setting too...I can actually get away by just setting my light cache subdivision to 500, and the sample size is just at the default, 0.01.

i set it to medium, then go to custom and set my:

HSph subdivs: 60
Interp samples: 40, but most of the time they are all in default

then set my noise threshold under rQMC Sampler to 0.001

The only once i mess is my light subdivisions, which are set at 25.

Hope this helps....i stand corrected by the way if some of these are incorrect.

srry "Critique1407" ndi ko kinonsider yung pc maaring tama din sila kc yan yung settings ko dito sa office ( medyo mahigpit dito sa office ayaw nila makakita ng mga splotches kaya mataas yung value ng settings ko)

Try to check also some overlapping ng poly. thumbsup

Napansin ko din sa scene may window sa left side ng image which i assume na dun galing yung light source.Try mo sir ng hwag idikit yung vray light sa kahit na anong poly either ipasok mo right after the window or move it back ward.kung nsa labas sya bro check mo din yung material ng window. Then yeah add more passes.

aside sa suggestion nila sir. nakita ko sa pinost mo na settings doon sa vray modifer...

"tick" mo yung *Store Irridiance Map* sa vray settings.

Tnx po sir edwardbctech. Mga sir eto po ung settings ko sa IR
HSph subdivs 24
interpolation samples 24
Light cache subd: 500
Environment
GI Environment=HDRI
Passes=2
Color mapping=Linear
gamma=2.2
then the rest hindi ko na pinapakealaman... hehe
Panu kasi gusto ko magexplore ng settings na mabilis tsaka maganda... di ko pala dapat pakialaman maxado ung mga settings. Tas Linear Work Flow ung ginagamit kong procedure kasi contorolled naman sa Frame buffer. Try ko po ung mga sinabi nyo. kaya lng. help naman po sa pag intindi ng maayos na IR settings.

nice comments & suggestions bro...i always use min 3 & max 9 in dmc sampler rollout..

v_wrangler wrote:ya know - the spots or the leaks means that you have very low GI hemispherical subdivs.

One thing I'd suggest is to try first using the irradiance presets , low, med then onwards. Do not play around with the custom settings if you do not know how to use them. There's a reason why the presets are there.

Regarding edward's settings above:

A global subdivision value of 2 means all the local settings are multiplied by a factor of 2. The setting above is what you call the universal setting (min 1 max 100) which will override almost everything. Its a sure fire flickerless approach but you better be ready for longer rendering times.

I personally use DMC but around a min or 2-3 and max of 6 to 9. And my material glossiness ranges from 24 to 32.

I know I just made you confused even more.
In the meantime - adjust the irradiance settings and see if that improves the rendering quality.
