hi

we did proposal for at single-family house as a part of a invited competition.

sadly we didn't win - but i learned a lot in the process.

thanks

looks like a good effort, I like the 1st image

Thanks marvez.

It was quite some work.

And afterwards one think - what could we have done different......

But as always - it's the main idea that counts.

Waves are great. It looks like you are using Direct AO. You should try path tracing, we can get almost the same render times that we do in DirectAO but the lighting will be much nicer.

I've used PT for all images

hi 3dgeeks

i can see what you mean - i have used max 2000 samples, that's proberbly why they look like direct light.

i needed them in 5000px x 3500px, and could not wait more than 2-3 hours pr. image. but i might use some wrong settings.

PT kernel is bad option because appear (very) hardly caustics in bridge walls from waves of sea.

Should PMC kernel with default settings except: ~80,000 samples/px (resolution of 1002x602), parallelism 1, 1000 rejects, no "caustic blur" because your GTX 780 Ti (I also but EVGA 780 Ti Classified

) is very fast.

PS: If your resolution is 5000x3500 then you may reduce from ~80k to ~8k samples/px for appear very good caustics.

wave of sea - specular material:
-reflection 0.6
-transmission 0.99
-dispersion 0.004 (must enable dispersion due to the real life

)
-index of refraction 1.32

Hi nuno

I'm just an architect that tries to create some decent images

It seems that you have a large knowlegde about the different kernels.

Could you please spell it out for me - what are the main differences between PT and PMC? And when to use what

I didn't even consider PMC, why? I don't know :-/

Would I have had a better and faster result with PMC?

Thanks

well just trying the PMC kernel, it almost require the double rendertime - that's simply to long time (time is money :-/)

maybe some tweaks can reduce the time....

Ok but you're not worried because PMC is more (much) efficient appear caustics than PT. Tweaks are faster but it may get less photorealism.

To study PT and PMC kernel - manual and search "pmc". - Sorry for old version "2.00"
