Hi all,
I am having rendering issues when I try to render high gloss plastic parts. There is ALOT of noise. I have a back, front and side emitters with 2 black bounce boards, your general studio photography setup, also an environment which is white.
These are all multi lights so I can post adjust.
I am not sure how to attach an image for this post.
I'm sure this has been discussed many times before but I am unable to find anything that truly helps,
Many thanks
Lance.

Upload your image to an image hosting site like photobucket, then paste the link in your response. Are you avoiding extreme RGB values in your plastic materials? Generally it's a good idea to use no higher than 240. Also, if your environment is too bright, it may make your emitters calculate slow, so try to balance the overall lighting levels, then you can adjust them with multilight.

Is there anyway to upload images, screen grabs to this posting service? as I don't subscribe to photo bucket or other image hosting galleries.
I could also upload my plastic settings too.
What I do is create a material choose wizard/plastic and make it around 65% glossy with no roughness.
The colors are RGB and do have a 255 value in at least 1 of the channels.
Thanks guys,
Lance.

For the uploads I'd suggest Dropbox. You get a couple free gigs of storage and you can share images or any other file types.

As for the material, the first thing anyone will tell you is to get rid of that 255. Knock it down to something more like 230ish and then people will start talking to you. Until then, you'll be the fat girl at the dance.

BTW, you could also try Half-Life's method for shiny plastics. Basically just a diffuse white material (roughness 97, ND 3, Force Fresnel checked) with a Coating (10000nm thickness, Ref 0/90 = black, Nd 1.491, and Fresnel checked).

Even though it uses a coating it seems to actually clean up quicker than the Wizard plastic - particularly with white plastic.
