First attempt at Kerkythea - your opinion, suggestions pleas
-
thanks for the tips. much appreciated. I've smoothed the surface - it looks like the little spotlight refractions are still scattered about.
here's a cleaned up version of the previous.
-
For the refractions you could probably just change the angle of refraction in the material properties, whatever you need to do with the water Is going to be in those properties. And I still don't see any antialiasing, are you waiting for it to finish completely?
-
for s first render... that's pretty nice...
-
thanks Kris. and thanks for the suggestion to do a night render in Kerky too. that was the nudge I needed to download it and dig in!

I had to go, but I'll take a look around again to find the antialiasing settings. I changed a smoothing angle for something in an attempt to try softening the refracted light... I'm still learning to crawl, you know.
thanks very much for your helpful suggestions. I'm eager to learn.

yes I love the night views... and your stars are just awesome shinning through the trellis... and the light at the bottom of the hot tub is perfect.

I'm having trouble eliminating the little spotlight refractions from the water - it shoots little blue spots up above and around. Anyone have suggestions as to how to reduce this effect?Also, the jagginess in the water is undesirable. I could fix it quickly in Photoshop, but it woul dbe nice to be able to render it smoothly. the water surface is physically bumpy. I used K to smooth the surface - could it be helpful to smooth the surface before exporting from SketchUp? (I didn't soften the edges).
ps - thanks to OzKid for the boat. Is it standard professional practice to not use other people's components in your models? Or just to ask permission first? Sorry I'm not familiar with etiquette.
how put the texture of the water ? its really cool you sorry iam new . i like a pool but ia dont have waves water , i only have the texture water.

mexico, I found this tutorial on a K site -http://www.kerkythea.net/phpBB2/viewtopic.php?p=18890&sid=f8b73bdaa110ecf236ef04b6620abbb7%20b6620abbb7
I downloaded the large video file but never got it to work - just audio - but it was enough to step through most of the tutorial.
As for the bumpy water, I just made a mesh with the sandbox tool in SketchUp and used the Smoove tool to make a bunch of bumps and valleys. There might be a better way but I don't know it Smile it took me probably 20 minutes.
Bruce, thanks for the compliment. It is very encouraging.

ArchitectBoy, I'm waiting on a render with AA enabled. Thanks for the helpful tips
It just occurred to me, could the little spotty refractions be eliminated by changing the lights in the bottom of the hot tub from spot lights to omni lights? They're in little recessed cans, so it should still illuminate the tub properly - maybe with some tweaking - and then the pointy little refractions may become more like soft blobbies of light, which would be perfect...
Any thoughts on this from experienced K folks? Thanks!
-
Most of my Kerkythea stuff doesn't use lights like that (just the sun and a back light) so I don't have to much experience in that area but it does look like your spotlights have a narrow angle on them (do they?) if that is the case than either widening the angle or changing the to omni lights would work.

Hi Nick,
First of all, I suggest that you post your question at the KT Forum...
This forum is GREAT, but I'm sure that you'll get much more qualified help at the KT Forum...
I wonder what material you've used for the water and also what render preset... Confused
To me it looks as if you haven't been using one of the render presets where caustics is present, but I could be wrong...
Have you also remembered to amend the Global Illumination Method in the Render Rettings..??The material is also very important, and you can find some very good and realistic water materials in the KT forum...
Looking forward to see the progress you're making on this...
Cheers

Kim, thanks for tips and for the encouragement.
I'm new at this, so any tidbits of basic information would be very helpful.
I just used a standard glass material for the water (as you said in your tutorial), but didn't apply a bump map because I made the model itself bumpy. Does this answer your question?
I have generally been using the Photonmap - Quick render setting, as anything with caustics or AA seems to take multiple hours to render. Is that normal or could it be on account of the many lights and large model? I am running on a Pentium 4 3.20GHz, 1G RAM, Nvidia GeForce 7600 GT 256MB. I had amended the Global Illumination settings as you desscribed in your tutorial, but I gather now that it doesn't matter if you don't use a render setting with caustics... I am gaining understanding every day!
I will take a look around the KT forum for water materials - thanks for the tip

At the KT Forum, you can find many useful tips and tricks... And if you can't find an immediate answer to your question, you can post one and the users there will always try helping you...@unknownuser said:

I've made the Getting Started tutorial, but not the water/pool video tutorials...
Any way - a glass material will be the right choice...@unknownuser said:

Also the choice of materials can increase the render time significantly, but it's something you'll learn along the way...In my opinion, you should only use the Quick render preset for tests... When you're happy with the materials etc., change to a higher preset and let it run during the night, while you're asleep...
For a scene like this, I would use the MLT preset...
It will take several hours to clear up, but you don't need to let it run for all 10,000 passes. At around 200 passes I'm sure it will be very clear, and remaining noise can get removed by using a program like NeatImage...@unknownuser said:

If you have done everything Fade has described in his video-tutorial, it's the render preset that will do the trick for you...Cheers
