Kerkythea render
-
They look good Tom. You are way ahead of me in Kerkythea. I tried it a few times just recently and got frustrated. When I have time, I hope to play more.
-
I've seen those, already, Tom (posted somewhere I remember)
Really nice ones considering that you have just started this.I particularly liked the one you linked in here then, too. The glass effect is great!
-
thanks you two, I am starting to get the hang of it. (lighting is my hardest part.)
AndGaieus, I had this posted in face book, maybe thats where you saw it.
Yes the glass effect is the coolest feature, but it takes sooooo long to render. I don't know if it's because it's "thick" (as opposed to a single plane/face)
anyone have any ideas on how to speed it up? I just loaded the glass library from Kerky site, but am reluctant to try anything too large.

Nice render, how long did it take?
As far as render times, I dont know about kerkythea but anytime you do refraction (which is the bending of light as it goes across an object, it will takes a long time to calculate. The bigger the object is in frame the more time it is going to consume. One thing you can do, and I dont know if Kerky lets you do this, is to control the amount of bounces the rays will take as it goes thru the glass. sometimes 5 or 6 bounces is enough. See if you can control the bounce, that will help you reduce rendering time.[stuckon3d]

hey stuckon3d, geez I don't know exactly how long, but I'm thinking about an hour. I actually ate lunch and returned to see it at 90%. I will look around for "bounce" I haven't seen that acual word but the "glass" used has the following settings:
refraction: index of refraction, and dispersion
bevel mapping: smoothing angle
there are a few others that I pretty much know what they do, and some check boxes, but one of the 3 above might be Kerkythea's "bounce"?
I'll play around with em, see what works.

Can you perhaps provide a link? Im having a stupid moment and cant seem to find the glass library...

This is a link for the material downloads in the Kerkythea Repository, if you read through the Kerky Forums there is also materials made by some of the users that are really good. http://www.kerkythea.net/joomla/index.php?option=com_remository&Itemid=42&func=select&id=3

ditto.
there is one named "car paint" that is sweet!

Hi Tom,
You can modify any of the settings in KT to the most deep and advanced degree.
I don't like to do this because I'm lazy and in a hurry.
So I go for the presets as Giannis has optimized them beautifully.But to reduce the refractions and speed up render times (two glass surfaces close together will bounce light back and forth until the cows come home) try this:
Render>Setup> now lower your tracing depth on the bottom of the Global Illumination tab... to 3 or something...
Also, now when you run the render, be sure to choose 'custom settings'.
For better lighting, choose a high-res global sky Clipi made... this will give you instantaneous lighting for your scene, nothing to set up. or download an HDR light probe and load it in the spherical sky slot of the sun and sky wizard. no sweat.
ps - when rendering with only one light source, such as this scene, you will find Progressive Path Tracing render method very fast, and as it's unbiased you will see a great preview in only a minute, and in an hour or so a very clear render (depending on many things, but for your scene at 800x600 I guaratee it.)
-
Fletch!!! You are the man!
Although I haven't attempted the hdr stuff yet, your suggestion in settings works great. And since I was reluctant to change the settings in there without knowing what they do, now I went and changed the photons and others, and sped up the time even faster.
can you see the difference in the two images here???

one took 4 minutes, and one took 11 minutes.
the settings are shown there too.
off line they are even bigger and I can only see a very faint difference.[CartographerTom]

great renders, tom. imagine what you will be doing very soon. i can hardly wait to get my hands on kerky (as a mac man i am still waiting for the mac port).
cheers.
-
Tom,
Really improving, nice!
Edson, the Mac version is already being tested!
-
glad I could help!
now go to Model>Insert>Infinite Planeapply a black material to it, and re-render. You will like it instantly better I think
Or even better download the sketchup object lighting studio from this thread.
