Interior WIP - first time BF/LC render

[simmsimaging]

Brett:
By saying BF bounces do you mean subdivs?
I have similar approach with individual mats subdivs when renderin with IM/LC.

The only reason (apart from serious urge to finally try BF) i went for such over the top settings was that i had free comps for rendering over the weekend ))

Thanks for the kind words guys!

Yes, sub-divisions. Sorry about that

i feel like 1/16 for DMC AA could be a nice starting point for me now that i ve started dig in the BF/LC more...

how about you Brett?
whats your experience with glosier scenes??

I have usually defaulted to 1/40 actually, but lately I've been using 2/20 to avoid some problems that popped up on a job a while ago. I forget the exact circumstance, but Vlado suggested raising the min value to 2 and it worked. I did not really note any hit in render times so I left it that way since

If all looks good then I might experiment with lowering the max value, but I really can't say I ever noticed a huge difference in render times so unless the render seems unusually slow I don't bother. Perhaps on smaller renders with many frames (animation etc) it makes a difference, but for hi-res stills I didn't notice much loss/gain between 20 and 40 in either quality or render times. I have not tested it exhaustively though...

Anyway, I very rarely need to do more than tweak the noise threshold for DMC - generally my GI settings stay the same on almost all jobs. Been experimenting a bit with IM/LC lately, but it honestly seems like more trouble than it's worth. I wasn't getting a huge difference in render time, but probably that is my lack of experience with it.

Let's not forget that we might also smudge the noise a bit with a bit of AREA 2.0 Antialiasing filter

[simmsimaging]

I never use AA filtering at all I actually like a bit of noise in my renders. I'm often adding them to photos, or using them to replace photos, and that bit of "tooth" gives them a more realistic quality. Even with complex materials there it often helps to add a bit of surface complexity that adds realism.

Just my POV.

hmmm... here's piece of 3500x2480 image - wall piece ... with 1/24 DMC and 0.008 sampler. I think the noise is too HARD.
Wall in front might be ok but the one in dark is a bit too much I think.

[simmsimaging]

I would agree, that is too much noise to me as well.

do you guys keep adaptive amount in DMC sampler at 1.0 ?

[simmsimaging]

I do, yes.

thanks for your input on this Brett!
