I've been trying out a number of stainless steel materials for a kitchen rendering that i'm doing, however it seems that most of them put off little dots in my render.

Would anybody perhaps have any quick rendering stainless steel materials which dont seem to counteract with other materials?

hard to solve without having the scene for testing. You could try changing one of the steel materials you already tested from "additive" mode to "normal" mode. In some cases this reduces the noise.

Show us the little dots.

cheers brian and kurt. I have been cancelling it as soon as i see the dots so i will let them render a little more and then send it through.

Seeing the rendering will help a bit, but usually the reason for noise and dts are not in one singel material, especially not metals. Normally it has to do with emitters or glass materials, or a combinaion of several issues.

There might be a fair few different materials that are intersecting which makes it confusing.

my light emitters are simple recessed octagons and the stainless material is one which i got off the mxm board. also a ceramic coating for the cabinets.

also the preview window has little fireflies all over the picture, which im guessing is it pre-empting that there will be more of them the higher the SL gets?>

Thats also SL 16.18



Cheers

Are you using simulens here?
I've seen this some times when using simulens, try turn it off once

and turn off reflective caustics also

cheers guys.

I'm not sure if i'm using simulens as i wasn't sure how to set it up (using 3ds Max)

But Also, would turning off reflectice caustics take away some of the realism? Obviously my images need work but i suppose anything that adds to the effect would be good.

Cheers,

also.. which one would be better. indirect caustics for reflection or direct. Or both?

Regards,

Nik

turn off both , neither are necessary in this render

thanks pip,

i'll turn them off and re-post the result. What do these effects provide in a render btw? Does it just add to "reflectiveness"?

Reflective caustics (direct) are patterns caused by direct light bounced off reflective objects.
Reflective caustics (indirect) are patterns caused by indirect light bounced off reflective objects.

Refractive caustics are caustic light patterns caused by direct light going through refractive objects.
