Kind of carpaint

Carpaint ? Looks like aluminium vinyl foil or silk

neat isn't it, but it's just the carpaint material, but instead of phong it uses diffuse and oren nayar for each of its blends.

Im very big car enthusiast but this isnt carpaint

it looks like vinyl foil , like this frozen grey

I never said it was, I said it was 'kind of a', because I downloaded the material, and the only thing I've changed was the material type from phong to diffuse/oren nayar. Pretty much about it, the original material is that of the link.

It's still rendering, 2 hours in at 1900 samples!

my advice as before on dA: don't use MLT unless you have to!

BiDirPT

hmmm, it looks like MLT noise in the image it's a diffuse transmitter on the right side? that might explain the extra noise (compared to directly visible lights).

should be PT but with high SS

Yeah I know yes it's a semi transparent paper/lampshade sort of material!

I tried PT on it's own but couldn't get rid of the fireflies!! high ss?

EDIT: Ohhh super samples? It's currently on 4 with BiDirPT

yes, supersamples...i knew its 4 or 5

So would PT and ss =6 be any good?

you'll want to use bidir because of the diffuse transmitter.

Left it running over night on PT with ss 6, 10 hours down and 10k samples;
