Ok,... Sorry,.. i have many stress,.. in my day life, so i'm not allways as fast in thinking as i would I have allready understand...

reflection blurring for wood texture in furnitures:

reflection: 40%
reflection blurring: 90%

juli51_forum · Post by **juli51_forum** » Fri Jan 26, 2007 12:20 am

I have tried reflection 20% with hig reffletion blurring.. about 200%, and with low reflection blurring about 40%, without big changes in extrange color points amount

I have also tryed without refletion blurring but with specularity and difusse and 0%reflection blurring and still geht them....

There must be something else,..or somebodymus have had a similar problem...

what else can i try?...

Please do not post tiff files. Use jpeg or png.

Have you tried turning into indirect mode and see if the grain is gone?

juli51_forum · Post by **juli51_forum** » Fri Jan 26, 2007 2:17 pm

yes, it's in indirect mode all the time,.... as you see in this A4 sample, the wood on the floor seems fine, but in the furnitures has extrange small yellow points all around that shouldn't be there, and I can't find a logical explanation for that, for i've touch blurring reflection settings,... hig and low or without ,... without success,...

For this scene:
difuse: 70%
specular:39%
glosines:29,5%
reflection:19%
reflection blurring: 200%

Well rule #1 would be to avoid glossiness...
And using glossiness in conjunction with blurry reflection is completely redundant and begging for trouble.
Glossiness = aproximation of blury reflections so only use one of those (I recomend blurry reflections)

Ok,.. i finally found the problem,...after a horrible weekend,....
I don't know exactly way but it has sometihing to do with inverse distance shadow of light in the room,... as I just set it to linear fallof,.. it simply dissapeared,..
so,.. if somebody has the same problem as me,... extrange clear points in surfaces as in image below,..... try change inverse distance fallof,.....

thanks a lot to everybody,...
