CoolColJ's test pics thread

Hmm..so much indirect light...nice.
That's exactly why i love unbiased renderers

yeah this is the kind of scene I used to try to render in a GI style renderers years ago, but could never do it without excessive splotches and cranking up the GI intensity to 3-4x

In Indigo, it just works straight away, especially with exit portals

that looks soooo amazing can't wait for t7render

turned out better than I thought as well, V0.9 Test 7 is going much better


I decided to revisit the SSS liquids again for V0.9 Test 7, and can confirm they render properly now, at least with Bidirectional MLT.
MLT renders faster but the results are different..... milk looks grey and more watered down... Might have something to do with MLT not being able to sample through glass as well

I used my watered down versions - Milk, Coke and Apple Juice. Milk with my RGB scattering values around 110,130,140 work well, and those are pretty high scattering values already, but nowhere near the 18,000 to 22,000 values in Whaat's Milk values!!

I tried a render with Whaat's milk values, apple juice and Apple+ milk mixed together. And it looks right as well, but renders way slower than my values, and the mixed version in the middle doesn't look much different from the full Milk value.
I rendered at small sizes as well, can you imagine how long it would take to render at larger sizes with scattering values in the 18,000 to 22,000 range

both pics rendered in the same time frame - 30 to 40mins...my Milk values are much more converged and reached higher sample rates

[CoolColJ]

there is light at the end of the tunnel!

an accidental render that turned out pretty cool, impressed how realistic Indigo can make such a simple unprepared scene look! Yeah there is a light at the end of the pipe

black bits are smoothing errors I suspect

[alex22]

Do you think it would be possible to do an endoscope

[CoolColJ]

yeah maybe, that was the idea I had, something like that when I thought about trying a light at the end of the pipe when I liked what I saw with the random placement of the camera

little experiment with BbB's scratch map
not only for bump map and exponent map on a phong material, but also as a clip map for a blended diffuse textured dirt layer.
So I think this means that the scratched areas have no dirt, being darker, and the grey areas of the map have moderate dirt levels etc

Skindigo's 4 UV sets per material is very handy

will use this in the final version of my watered down SSS liquids render I think. Such a nice general purpose scratchmap

starting to get a hang of Indigo's material system. It's simple on first look, but quite powerful under the "surface"

[suvakas]

Why do you need 4 UV sets for this?
Do you have to UV map every texture separately in SU?

[CoolColJ]

I didn't use all 4 in this case, but I assigned each "layer" a UV so it can use the map in different ways. It's kinda complicated, and does my head in sometimes

all scratched up and dusty
A "quick test" of the material, I like

the edge of the shadow is a bit transparent looking? I'm wondering if the clip map of the dust material is somehow making the object partially transparent even though it is blended with a solid phong material

[CoolColJ]

test render of the scene - it's up to about 400 samples, 4hours....
really slow. Milk and glass is not a good combo, those high scattering values of milk is a killer!
although 4 hours in the context of an Indigo render on my PC is quite short

Still I shudder to think how long it will take at 1024x768 or higher, 4 times longer at the very least... and I need to get to at least 3000 samples...
30 hours from my estimates, and more if I want to reach a higher sample count.

Really tempted to grab a quad core this week, it would finish this scene in 8 hours tops at that resolution..must resist temptation...

anyway the new Specular and SSS changes in V0.9 test 7 are sure rendering differently. I am seeing new things in the glass, although some of it looks funny to me

[suvakas]

Then stop your misery and go and get a quad. What are you waiting for?
I'm so used to my Quad that it actually feels slow. I want faster speeds already

[CoolColJ]

I've waited for a while, so no harm in waiting a few more months for Penryn to come out
There are usually years between each computer for me, so I like to make it a nice upgrade. I went from P3 500mhtz to P4 2.8c at 3.2ghz, now a quad will come soon

You should overclock it
or get a dual quad

[suvakas]

Gotcha.
I hope your strategy pays off. My need for speed is greater than my patience

[CoolColJ]

I like to feel the whiplash

I have a general rule to not upgrade until I can get at least a 3x speed improvement, but generally I prefer 4...
This way I get my pennies worth. Computer gear devalues so fast!!

So after a quad, it will be a long time till I upgrade... until 16 cores comes out at least

[BbB]

My eyes watered when I spotted an opening promo at a nearby electronics superstore last week. It was a Quad Core with 2gigs, a top of the range graphic card and a 500gig HD for 600 euros!!! I smacked myself for upgrading too soon... Mind you, the way the dollar is going now, euros like me will soon be able to get that kind of stuff from cheaper still through US friends...
