Irradiance Particle test render

Unang subok sa irradiance particle. HDRI lang ang gamit na light source. Hindi ko alam kung tama ang settings pero for the sake of discussion pinaskil ko na rin dito.



Heto settings:


IMAGE UPDATE:

Galing sir ng test.. meron akong ginawang tutorial sa Irradiance Particles basic at advance sobrang bilis mag render ng Irradiance Particle compare sa Final Gather..

here are some of my test also..

Ayos ito sir. Ano settings nito? Pwede ba masilip ng settings?

Sir ito yung settings ko .. sample test render ko disable mo muna ang final gather .. Irradiance particle lng ang enable mo tapos lagyan mo ng GAMMA and GAIN ang HDRI mo para mas sharp sya.. gagawa ako ng tutorials from exterior to interior hintay lang kunti .. na discover ko na ang secrets settings nya .. i won't go back sa final gather hehehe

Yung output ko medyo grainy compared to your smooth output. Napansin ko sa settings mo, interpolation=Always at mataas yung Rays.
Tanong ko lang sir, ilang ulit mag "render" yung precomputation mo? Kapag umabot bang 100% pwede na bang i-cancel at nagsave na ba yung IP map?

two parts kasi yan .. ganito ang trick dyan.. una render mo muna ang importons pag hindi sya naka enable mag calculate parin sya tapos next part is yung Irradiance particles.. medyo matagal lng ng kunti pero once matapos na make sure na naka save sa file .. after that pwede mo ng gamitin sa scene mo.. you can add light, change materials, etc. basta unang gawin mo lng lagyan mo lahat ng plain white material lng na A&D with ambient occlusion tas gawa ka muna ng file to be read later .. afte na matapos mo gawan ng file sobrang bilis na lng ng rendering mo .. kahit gaano pa kalaki ang size ng image mo

mas maganda at smooth yung IP sa FG ha. base sa mga images nyo. FG seem blotchy and noisier, whie IP is so sharp and smooth. and base na rin kay ed mas mabilis pang magrender. very inspiring. keep sharing your MR output.

kahit na hindi naka-enabled yung importons i-render for computation? tapos yung irradiance particle naman ang i-render for computation? hindi ba pwede sabay tapos naka-check yung "rebuild"? medyo naguguluhan na ako.
hintayin ko nga yung tutorial mo sir. thanks for the input.

oo nga sir nomer, smooth at malinis nga. pero somehow parang gusto ko yung medyo may konting grain para medyo realistic yung dating. well it all boils down to personal preferences.

Another test for interior, ginawa ko muna mag render ng simple white color lng muna with AO, tapos nag calculate ako ng IP tapos after that save ko sa file ang IP calculated tapos nag start ako mag add ng mga texture , light at try ko iniba ang camera position so far satisfy ako sa result it took me 4 mins to render below.. 10mins sa IP calculation

IP Calculation white color with AO



ito naman ang modified version but still using the save calculation above. nagkamali lng sa material sa cornice.

Ayos ito sir. Question: kagaya ba ng pag-calculate ng FG ang IP? Kahit mababang rays count lang ba for computation tapos pwede na itaas ang mga rays for final render?

Pansin ko lang may mga blotches sa window frame at sa baseboard.

yup pag standard material lng pala gamit mo magkakaroon ng spots .. ginawa ko nag compute ako ng low res lng na IP calculation tapos na save ko sya tapos after that change ko na lahat ng setup ko add ako lights, materials .. etc. same smoothness pa rin ang na achieve ko at mas mabilis na rendering ..

Additional Testing i'm almost done with the tutorial.. I'm very amaze with the result..

imagine how fast is it compare to final gather and notice also the details ... i'll post the tutorial very very soon..

Galing nito sir eric. Ang linis ng output.
Sinusubukan kong i-render ulit yung scene ko pero nagkakaproblema ako sa sharpness ng image ko. Mataas na AA na ang gamit ko pero sa edge may problema. Hintay ko na lang yung tutorial mo.

WOW!!!!!!!!!!!! Keep sharing mga masters and teachers!!! wait ko yun tuts niyo dito ha?

di ko maiintindihan pero wait ko din tuitorial hehehe

sir edosayla and sir logik, may mag settings na po ba kayo na maiishare? makakatulong po ito ng malaki sa next project ko salamat po ng marami!

Nothing special po sa model, just a borrowed one, only used it for this test.

Mga sirs, heto naman po yun test render ko with Irradiance Particles... Should be better with Importons, but a bit longer in render time. Will post with Importons soon. Sana po tama yun render settings ko... Sir edosayla and Sir Logik, sana meron na yun shares niyo...

btw, render time is 22 min 41 sec... I am quite happy with this one rather than my FG renders na minsan infinity and beyond and waiting time hehe

Interior hindi ko pa nasusubukan mag-IP. Try ko din tapos i-share ko na lang experience ko dito. Good luck.

A little bit of tip/note when using Irradiance particle: Using Normals as bumps will create unwanted render artifacts -black spots on the surface where you applied the normal. Correct me if I am wrong. Just wanted to share this.
