Quote - vilters- Why does the bucket size have to be a power of 2? Why is 32 the best?

jura11- Just so we're talking about the same thing, by "GC", do you mean "Gamma Correction" or something else? How would gamma correction affect the smearing in an image?
Also, I'm not using any lights in my scene- all of the illumination is coming from the Ambient Value of the "Lights" materials.

And just to confuse everyone, let's throw in another condition: I need the image to render within a 1/2 hour or less.

The reason is this: if I'm going to use this technique or render settings for promotional sales images, I can't be spending 2-3 hours waiting for one image to render. If I have to make 9 or 10 images, then that's 20 to 30 hours just making images!

 

Hi VP

 

Yes we are talikng about the same thing Gamma correction,as I've said,I've tested several settings with GC on and GC off 

There can be the yours problems if you are not using any light in yours scene and trying to render with only emmiters(Ambient Color and Ambient Value set at 7),i would use lights and lower ambient value,this can be good start

You are want to render with 1/2 hour or less,my god wish I could render my scenes in such speed,my renders takes around 20-45mins(longest render took me around 4hours) depends how densily is populated or how many props etc is there,but usual time is around 20mins

Agree if you are doing this for promotional purposes then lower render times are best way

 

Thanks,Jura
