Q: My renders are a bit grainy. what am i doing wrong?

just a try:

- there isnt enough light to fill in some black and gray spots all over the space thats why it turned out to be grainy in some way
(and my advice, shed some light)
- tweak down your noise threshold from the default 0.01 to 0.005-0.001
- jack up your hemispheric subdivs (hsph) of your irradiance map (if youre using it) from the default 30 (guess so) to 80 max
- might want to include interpolation subidvs (interp) of your irr map from the default 30 (guess so ulit) to 60 max

if you've got powerful rig, you can jack up those subdivs and noise thresold to its max limit, 100's for the subdivs and 0.001 for the noise thresold.... hope these helps goodluck

thankx poh sa reply! subukan ko po gawin suggestions nyo!

i hope may iba pang mag post sa Q&A thread na ito at yung mga master mag reply!

su thread po ata ito ser.??

Vray for SU daw eh.. di Vray for SU...

pno pg prang sunog ung wall pg nrender or minsan s floor and other object. s sobang light b or kylangan lng ng setting s ilaw.. tnx

both! actually pwede mong gamitin ang physical camera o color mapping. pero yung madali ay yung bawasan ang light intensity siempre.

pano i-manipulate po yung bumps sa mga texture po sa vray?
salamat po.

sa multiplier. si kung nakakabut na yung bump image mo yun imanipluate mo yung bump strength mo by using the multiplier. you can also invert the bump effect by ticking invert.

Q: Paano po ba yung mga renders na may parang dark sa edges? material po ba yon or sun settings?

salamat po

any images to explain. what is yur setting. probably dark blotches. my quick guess ay mga areas na hindi na reach out. its hard to explain pero yung vray maraming sampling na ginagawa. at isa nito ay ang tinatawag na adaptive sampling sa mga dark areas.. tingnan mo ang adaptive amount mo sa DMC sampler. kung 1 sya palitan mo ng 0.85. yung default ng vray 1.0 ay 1, pero sa 1.05 ay .85 na.

kalawa kung irradiance map, taasan mo yung hsph subd mo.

so one at atime siguro muna a t tingan mo kung anung nagyari.

thanks a lot master nomer! ok ill try that

thanks so much for all the tips btw master, it helps me a lot!

good to know. so enjoy. sa susunod ikaw naman magsabi sa iba.
