Covered Walk (Updated - Problem Solved)

hello cgp... just posting this one. nothing really fancy bout the design, low budget... this is a proposed covered walk for the davao city national high school... just playing on some post processing in PS. I did some CA, Curves, Levels, CC, Glow Effect - adjustments on this one. please assess if i over did it....

the main reason though why i post this one is because of the color bleeding on the trusses area... ive tried the vrayoverridematerial, lessened the received GI on the vray properties, still lumalabas pa rin xa. so im calling for some help on this one. CnC will also be appreciated. tnx.






tnx to all who helped me figured out the problem

here's the final output...



playing with CA



WHAT I DID:

to solved the problem.... basically the problem is lighting and the only light i have is the vraysun. i tried adjusting the materials and received GI, but still color bleeding is there. so i tried tweaking the vraysun. the main thing that makes the light bleed is the shadow bias. i lowered it until the result fits. vraysun and vraycamera is a perfect combination but could also be very tricky.

also the unit setup plays a big role here. when we change our unit setup, say from millimeters to meters. the unit changes, though the default numbers on the parameters doesn't. so let us also be aware on that on adjusting our parameters numbers. on this particular scene i used meters, therefore the default shadow bias is 0.2... on millimeters units setup, this perfectly fits but on a meter unit setup, 0.2 meters is very big for shadow bias. i made it into .001 m and it gives me a very good result.

i hope i im clear.

tnx again guys... CnC is still very welcom

Sir vamp, may noise rin sa floor, w8 po natin mga masters...

problem ko rin ito minsan....makiki antay nalang din ako ng mga sagot from the experts...

mas ok nga na pinost mo to pre vamp...pra matuto pa tayo for troubleshoots...yung noise mdali lang ifixed yun eh..ayuz lang yan..my mga vray lights kb sa taas ng trusses mo?post mo wire nito bro para mkita natin yung mga lights n nilagay.. don't use vrayedgetxt ha, just the screen capture of wireframe mode...

here are some wires.... wala na pong ibang ilaw except for the vray sun.... i used the vraysun and vraycam combo on this one. for the noise on the flooring.. i guess thats because of the displacement i put on the flooring. di na xa mawala kahit i default ko pa ung size multiplier ng vraysun. another problem to solve.

boss vamp,,
i think hnd noise yang sa floor,,bump yata yan,,,
try nyo lng po,,
kc nakatry na po ako neto,,ngmumukang glossy ung floor dhil sa bump..

try lng po boss,,,

oo nga po bro.. di nga sa noise.. either sa bump or sa displacement na nilagay ko. tnx bro... il check on that.

sir vamp pwede po makita ang material mo sa trusses? i think nasa material din ang problem may glossies?

Ei bro nice renders here.maybe sa material bro.Or check out the poly baka kse may tiny gap between sa trusses and the roof try mo syang idikit na lng.Yun lng nmn bro.Happy Easter!

wow parang totoo! ah ganun pala dapat malayo ang ilaw, masubukan nga yan

magaling,,parang yung gumawa,,,

sir.. di ko nlng i screen shot.. medyo matagal kasi

nwei, what i did sa material ng trusses

just plain vraymaterial... with simple color diffuse

reflect RGB 30,30,30
reflect glossiness .95
subdivs 8

master jeff.. tnx... nwei, me gap talga xa... from the space ng purlins for the roofing and the truss... though aside doon po.. magkadikit napo talga xa. if ilapit ko kasi... mawala ung detail ng trusses... so i was thinking baka me ibang paraan pa po dun.. tnx again and for the appreciation.

@gardo.. tnx bro... nwei, i guess the distance doesn't really matter... sa adjustment ko lang yan, kaya lumayo ng ganun.. hinahabol ko ung shadow.. nwei, u can try it otherwise.

@ evilution... tnx bro.. for appreciating. do i know you?

A ok.So i guess sa material nga yan ng ceiling.

mga dude....

kung walang gap at walang light na pumapasok, isa lang ang alam kong dahilan kung bakit parang may lights dyan sa truss mo.
babaan mo ung secondary bounce mo dude...pa-try lang dude...
pag hindi pa rin, e magtanong pa tayo sa iba! hahaha dami magagaling dyan....

mmm.. ano po magagawa ko sa material ng ceiling? tinangal ko na po ung reflection nya... tnx...

na-try mo n ba dude babaan ung secondary bounce mo sa rendering?

dint notice the post yet master tovicz...nwei, il try it now... tnx...

i tried lowering the secondary bounce upto .6.. andun parin xa. at umitim po ung scene.

try mong mag override ng material muna sa rendering, para malaman natin kung sa material nga....

tapos pag di parin try mo gumawa ng bagong geometry, say box, tapos lagay mo malapit dun sa mga trusses kung ganun din mangyayari....try that muna....

troubleshooting kase, so kailangan talagang isa isahin natin to....

kk.. tnx po.. i will...

bro ayos tong post mo marami tayong matututunan... bakit nga pala kelangan na merong reflection ang ceiling mo saka ung mga wooden frames? kasi visible din dun sa green wooden frame na may freshnel sya. or hindi yan wooden frame? steel frame with paints?

try mo bro ulitin ung polygon ng ceiling mo saka create ka ulit ng new material using defaults. then assign mo sa bagong ceiling then test render to see kung andun pa rin ung parang self illumination. minsan kasi parang bug yan sa vray at max kahit inaayos mo na ayaw maayos. same din sa floor mats mo at polygon.

kung hindi pa rin maalis... exclude mo na lang sya sa vraysun mo then gawa ka ng pang daya na ilaw vraylight na nakatutok sa ceiling then exclude mo lahat maliban dun sa ceiling... hope makatulong bro...
