the gimp-edited version looks very effective, but noise comes out stronger...
You should increase prescale, I guess...
default's 1/1/6... try 3/1/8, or so....

Heh, a little quick on the post button are we...

I'm planning on just letting the final piece render for at least a full day to get rid of all of the noise. I'm doing a new render now with a gain of 20, and it's looking pretty good so far (even though it's only been going about half an hour.) Depending on how things go I may even just let this one go and call it final.

If you really want to get the hang of reinhard tonemapping settings, load an igi file into the indigo tonemapper (violet) and play with the settings in there. You'll soon get a good idea of what setting does what.

Thanks, I'll try that. Here's an idea of what things looked like in Yafray with no AA. link

[Edit] Here's the edited render 9 hours in.

indigos render definatley looks better

Well, 21 hours in and I'm calling it done. I think I'll also do a Yafray version to compare (I like the colors in that one better.) Now I just have to wait for CG Sphere to send me a new password because I forgot mine...

looks great

Crit (I know, it's too late, never mind, but you should read it anyway

): the lines have a bit of aliasing-artefacts.

This really isn't important

This post should show, how good your render is

Nothing to crit, than that

Well, I submitted it. "Spherahedrons" Now onto CG Sphere project number 2: A fluid sim vortex in a closed glass sphere.

O.o Great!

looks intriguing!

Thanks. I think I'll make it a little more creative by maybe adding a little ship being sucked into the vortex. I'm still suprised the fluid sim even worked!

Unfortunately, lots of water moving very fast means long bake times, even at low resolution. I did this res 70 bake for at least 3 hours. Here's an Open GL render to see it in motion. .avi 3 MB xVid

How "big" is that water?
y'know: If there is a ship inside, the water should be quite big

small ship .... 2m (very small

)
vortex .... 20(?)m
sphere radius ..... 10m

Make it that size in both the baking and the indigo rendering

Lord of the Rings Junkie · Post by **Lord of the Rings Junkie** » Mon Apr 16, 2007 7:35 am

The water is 1.5m in diameter, but I plan on making it a miniature ship. Maybe even with miniature people crying for help. Think Gulliver's Travels. I'll try making it bigger, but it will only wreak even more havoc on my bake times.

[Edit] Rebaking at 10m diameter and 70 res...

That animation is quite awesome

how did you make the vortex btw? Is it just liquid inside a spinning shell?
