Here's my final Brazil result, the big area light is weaker than my small area light, also emits less caustic photons. Result is not too shabby considering my hardware limitations and the time taken.

caustic map creation: 8 mins
render: 2hour 35 minutes

hardware:
P4 Northwood 2.8 GHz HT
1 Gb ram
physical memory used: 324,3M
virtual memory used: 391.6M
image sampling min/max: 2/2
dof enabled

dutch_designer,

Very nice effort man Thanks for the Brazil image (I will post on the main thread for you).

Yes, the small area light is ok to be stronger. That is how it was envisioned in the first place

So, far are you confident enough with that imege ? Do you feel it is in final quality to the point that you could sell it to a client for a catalog ?

[ivox3]

Heck yeah Thomas .......caustics, secondary reflections and subtle color washes are the reasons any render purist persists. It's a sickness and your sick with it..... We're all sick with it ......... Madness.... ...love it.

Hi Thomas, to be honest? No, I think the caustics need to be sharper for that. But both my skills and my pc specs prevent me from doing better at the moment. If this was for real and I didn't have Maxwell, I would probably have invested in another few gigs of ram..

[big K]

so finally, here is my fR2 version (had to tweak for the caustics) RT 5h 35min (could be optimised a little i think (antialiasing and GI)



caustics are not possible with area lights at the moment, so this one used point lights for the caustics)

[dutch_designer]

Trying one now with complex IOR.. can't remember off the bat if that's enabled in RC5 though.

[LarsSon]

This is my final with V-Ray ppt.

Rendering time 18.5h with 2xdualcore opteron. Wow!
If comparing to my home pc P4 3.4, it would render 6 times longer.
Total rendering time should be then 111h!!!



Gaustics are not clear yet. In reflection they are much better than Maxwell's,
but in surface they are too noisy still.

big K: i'm rendering one more version with FR and using rectangle lights.
Gaustics are rendered beutifully and realistic decay gives alot to this kind
of lighting situation.


-LarsSon

[big K]

yes, i think it should work. but you are using fR, right? and i have fR stage 2 for cinema 4d which has still quite some issues. this looks like one of them.
i have to report it on their forum. (Holger used also fr2 and told me he has also used a workaround)

But I can't see reflection of the coin's cautics on the silver ring. Or is it too weak to show clearly?
I made a 22 hour/lvl 17 render, to see if it would cure some aliasing problems.

I changed diaphragm settings too. I love the effect of polygonal diaph on focus blur.
I have no idea how much time/computing power it would take to get rid of most of the noise.

Yeah, I was going to ask you how you did that PPT so fast

In my experience PPT is actually very slow (2-3 times slower than Maxwell)
Here is my old try on this scene

PPT 31 hours

Hi peter,

Interesting choice of color.
Thanks for the image (it looks like you denoised it. right ?)

[Thomas An.]

michael

the caustics from the coins look a little different when using point lights (they appear like little dots ... which makes sense )

[Peter Tomasovic]

yes reduce noise, Adobe SC2

[Thomas An.]

Hi Thomas, to be honest? No, I think the caustics need to be sharper for that.

Yeah, all the elements are there (they are present) and I see the coin caustics have the right shape. Now it only needs tighter settings to even out the caustic areas that appear uneven.
