Kerkythea - setting up lights/scenes/materials
-
Hi all
First of all let me write couple words about me and my 3d experience. I started to use sketchup + kerkythea arround 2 months ago. Despite I learned modelling in Sketchup enough to get the satysfying results, I am still not happy with renders I make (I use Kerkythea). I am running out of ideas how to correctly set up the lights, scene, material in Kerkythea to get a nice (realistic) image. Can anyone help? How you set up materials/textures - you do it in Sketchup firstly, then just export to KT? Same with the lights - do you put the lights directly in Sketchup and then just export it to Kerkythea, or you just set it up under KT (no presets in Sketchup)? The same with scene. Create it in Sketchup? Or maybe is it just a matter of trial and error method (playing with lights, scenes, adjusting materials) to get nice (realistic) render?
To many question probably - to make this easier I am uploading some of my recent work - image only. I am still not satisfied with results. Maybe because I turn off the sun, use the background color - white, added ground (set white/grey colour). Each shelf has a price strip (plastic) but what I get is a terrible noise on some of shelf instead of nice transparent pcv plastic.
Anyway, thanks for any advice which help me to improve this render...

Hi, welcome
I believe "background color" is the worst option to get realistic images, you'd use instead "sky color" or better setup a lighting studio with a spherical background, you can find something also in the KT site.
About where applying lights and materials, is not so important...each person has his own workflow, I mainly put the lights directly in KT but sometimes I do it in sketchup, so the same for the materials...there's not a rule -
Hi tridem
Thanks for giving some advices. Maybe you know any good tutorial showing step by step whole rendering process (settings, lights, materials, scenes)? Such easily absorbed tutorial would be something for greenhorn like me...Just one question, while I was playing with lights, shadows, settings I usualy get overexposed image, or too dark, or something - I got sick off it...Is there any universal method/procedure you use or follow so that your works always look at least good (I mean at least on accpetable level) or is it just trail-end-error method (especially with lights and scenes) before the render looks OK?
Are there any interesting and easily absorbed articles/tutorial you could recommend? -
First of all I suggest to read the Getting Started Guide, from official website, then some good tutorials for beginners can be found here
http://www.sketchupartists.org/tutorials/sketchup-and-kerkythea/
majid's "KT Fast Start 4Architects" is quick and very good
Even I have written a book, but it's for a bit more advanced level...and only in italian, so farAs for the light settings, unless you use emitter materials there's not a exact corrispondence between the light intensity value and real-world measures. Let's say values from 0.5 to 5 cover most of needs (I'd start with 1-2 for artificial lights and a bit more for the sun, but usually the sun is correctly imported from sektchup), then you can adjust the exposure and gamma in the rendering window

I have tried another one (this time with lights)...but I feel like still something is missing...something which make this realistic. What settings you use to get a good photorealistic renders? What is the most important - lights? Besides I have a problem with transparent material (glass, transparent plastics)...

Remarks (what is wrong/what has to be improved) are warm welcome...Avoid fully saturated colors and pure black and white; 6%-94% range in Color value (in color selector "Hue, Saturation, value" -tab) is safe.
Enable soft shadows for the light source.
