blotches/splotches in dark areas

[spanish pants]

Hi everyone,

 

I could use expert advice. I am getting blotches/uneven coloring in my shadowed areas. I've tried bumping up the settings and it improved but it's still there. is there anything else i can try?

i'll post up my render settings as soon as possible.

 

thanks

yep post your settings and ill have a look!

if you're using the irradiance, will certainly looks to be the case, the size of the splotches is controlled by the irradiance map resolution (ie the max rate)...the variance in the color of the splotches (ie the quality of the samples) is controlled by hsph subdivs...the blending or smoothing of the splotches is controlled by interp samples.

 

you could easily remove the splotches by adjusting all 3 of these values

 

i would start hsph subdivs at 20 (since it has such a tremendous effect on render time) and increase only if absolutely necessary

 

i would stick with the presets for starters

 

i would take inter samples up to 100 if necessary before going crazy with the other 2 settings

 

if you are not already doing it, you should also use some vray light planes to act as fill lights in your windows and doors....it reduces the need for such high quality gi settings

Brian,

 

Just a couple of quick question;

 

If you are using LWF, would you still get the same problem with the splotches,

 

And adding vray planes to windows and doors, would lead to other problems of too much light wouldnt it..?
