Hi, I'm new at the forum and with this renders thing, and I'm looking for some help.

 

I'm working on this interior scene but i don't know why blinds look like that ): if you can see in the shadows looks fine, thats how it should look in the blind itself, the render took also 10 hours to complete but that may be because of my PC, it's a little old.

 

For the perforations I'm using a transparency map and I thinks that's all, so f you could help me that would be nice (:

 

Oh, and sorry for the quality of the image, a bigger image would have taken like a whole day xD so, i will wait for your coments, thanks.

I am not sure if you can do this with the Vray version of Rhino, but set it to Adaptive Sampling, use 1 to 4, and turn off AA completely. It won't be the cleanest render, but I frequently use it for proffesional production. Doing that should make the image crisp.

 

Also, ...another tip that is for Max, but may help. Use no blur on opacity maps. In fact, try to get your opacity map down to just 2 colors. Black and white, no grays.

Ok, I'll try that. That will increase my render time, right? and by turning off AA you mean turning to Zeros? because at least in rhino version there's no option to turn it off completely

Sorry, I meant Adaptive DMC.

 

But as for AntiAliasing, does Rhino not have this? No Area, Video, Box, Mitchell, Catmull-Rom, Etc...

Ohh, my mistake! sorry for that, i thought AA = Adaptive Amount, I always thought that haha yeah rhinos have the option to turn AntiAliasing off, but in the sampling options I only have: Fixed Rate, QMC Adaptive and Adaptive Subdivision.

this looks to me like a sampling problem, the image is very small and the samples are too low, basically the render engine is having a hard time deciding which pixels to render. take a look at the shadows of the blinds at the back of the image and trey look like the blinds themselves. a bigger image would help and the samples of course.

Well, i've decided to get rid of the perforated blinds and simply use a surface with some transparency as blind, the results were driving me crazy so that's why, but thanks a lot for your help, later I'll post an image for you to see the results with the new blinds.
