Render challenge - water caustics

solo

Excellent Modo 401 show piece, so how is the new Modo so far?

Here is a faked caustic I did in December 2006, using Podium version 1.0.

This brings some memories

Well haven't played to much with it, only been test running it.....the "fur" ellement is just amazing...i'll see if i can post a sample of it used to creat a grass field.
as you could see the caustics also looks good, even though i have a dual core machine, it renders pretty fast (see the caustics render screengrab), i am now going to try out the blurry refractions...
but all in all, amazing.
it's a bit more aimed now for archvis with all the presets that can be used,
i am definitly going to learn how to use it, so i can add it to my archvis workflow.

congrats Solo... it is an art work, out of podium!!!

Well not totally satisfied yet, but though I'd post the progression.
Kerkythea
Water Surface is thin glass, IOR 1.33, color changed to blueish, Perlin Noise Fresnel added

Rendered with Preset 09 Photon Caustics Medium

if you are going to have a better result , maybe give a try over dielectric glass shader ... or maybe download waterpack I've prepared some while ago :

also less bump over Z direction is needed...and the best result for true caustics would be reached , using preset no 20...
also u may have your camera , just below water surface ( give it a try )

Hey those modo images are amazing!

Maxwell - faked!

Maxwell night - faked! 5 min test render! Needed longer!

majid

here are other renderes from differenr scene.. it seems that KT has good caustics handling , but the water material , doesn't let that the caustics be seen from top view ...

I tried something to.

Thanks majid
I hope to get time to try this. I do have, and use your waterpack quite often, (thanks for that), but when I try these challenges I like to try to do them from scratch to try and understand some of the principles, and controls and their variables. It also makes me go through some of the tips, tricks, and tutorials on the Kerkythea forum site, from which I always learn.
Thanks for the help.

solo....how did u fake the podium caustics?

solo

Oliver, it's done with a light and a caustic pattern overlaid onto a texture in PS, actually very simple. Now with blurred reflections and bump mapping it can be done even better.

thanks for the reply pete

dale

another attempt

Richard , that wood panel texture is great. Could you tell what it is? Arroway? Love that pool render. Nice, clean design.

Thanks mate the design is one of my own! The texture for the timber panel? The one with the screws in I might have edited an arroway and rebuilt to rid the tiling, fix colour and bump, add screws etc. I get so anal the screws even have the head bumped and discoloration of the timber around the head along the grain and the decking a slight cupping in the bump!! My mother was german!

LOL...I am using one made from the photo taken from the project I designed (self referencing )

Here is a KT photon mapped quick render
Lots of water features too.

Hi, here is my try using v-ray with GI sun.
caustics test.jpg
I followed this tutorial http://software.asgvis.com/index.php?option=com_docman&task=doc_details&gid=594&Itemid=439&uid=0

I used as primary engine Irradiance Map
And second engine deterministic Monte Carlo GI

Caustics On
Max Photons 100 Multiplier 300 search distance 5,0

Environment
GI: Sky, Sunlight,
Photon Emit Distance 100000
Caustic Subdivs 10000

this is my try....it's a simple box, with a flat rect. geo.
sent to modo401....textured and rendered

hello can i know how you did the water. im an paris architects and realy i need for a project. tnk a lot
