        Liam,

        I've long admired your Halo models, especially "Mombasa station." I used to live in Mombasa, and there will have to be a whole lot of economic improvements, to reach that level of tech. For those who don't know, an orbital elevator must be built on the equator. Mombasa is one port city that could fit the equatorial requirement.

        Regarding your render, am I looking at two super-imposed spheres? (It makes me a bit cross-eyed, to study it!) πŸ˜†

        I, too, have a lot to learn about Kerkythea. I've been playing with camera focus and depth-of-field, and hope to have a good render to post tonight. (It's "cooking" now.)

          yeah that halo project sure is a labour of love lol thanks. Havent done much to the new mombassa scene for a while but ill get round to it eventually.
          Yeah its two superimposed spheres slightly offset from each other to give a blurry effect. One was glass and the other a steel texture both with HDR lighting.
          Still a long way off learning to render which is very irritating as ive got drives full of hundreds of models especially my halo ones but nothing to do with them. Im slowly learning kerk but keep hitting blanks. I cant for the life of me find any materials for my scifi models, ive downloaded them all form the kerk website but there are only a few and havent found a website out there with materials 😞. Looks like ill have to work out how to make my own! eek

          These where the two renders form kerk:
          and this is what im trying to render at the moment but struggling on finding suitable materials 😞 if anybody knows a suitable kerk materials library let me know!

            well the render turned out very grainy so i dirtied it up a bit in photoshop so it looked like I had intended it to look like that lol, ive been messing about fir the past hour with the settings and ive put another render in but looks like it will be an overnight job as its only on 4% ray tracing! ill post the results tomorrow night fingers crossed they will come out ok, ive also put depth of field in but its really slowing the render down 😞

              I like the "illustration" qualities of the second image.

                Working with Kerky camera f-stop settings ("Scene> Camera" menu,) I eventually got the amount of depth-of-field blur that I was seeking:

                f/3.5
                Compared to the original:

                Initial render
                Yeesh, this is a lot more time-consuming than looking through a camera stopped-down viewfinder!

                  Here is another angle. I used the same lighting setup as the last one, changed the material to green gum and added a beige backdrop. I also changed the Camera F-Number to 22.

                    Wait, wait, wait... πŸ˜•

                    I thought that higher f-stop provides greater depth-of-field. Wouldn't f/22 give you a large range of in-focus detail?

                    Are you positioning the camera right up against the sphere?

                      Yes and yes. I put the camera almost dead on the sphere. I had to change the F stop to a larger number otherwise it was too blurry. On the previous one I did the camera was farther away.

                        Thanks, Eric.

                        I'm glad I have some photography experience under my belt, otherwise, I wouldn't even have been able to guess. πŸ˜‰

                        My test renders have been with the camera at greater distance, with 135mm "lens" to reduce perspective distortion. (I assume you're using the "standard" 25mm lens.)

                        My last render, with which I am delighted, took a lot longer to render. I assume this is processing "overhead," due to the out-of-focus regions. I note that the anti-aliasing time went WAY up.

                        From the Kerkythea console:
                        Ray Tracing (13839 seconds) -- 3 hr, 50 min, 39 sec
                        Antialiasing (23945 seconds) -- 6 hr, 39 min, 5 sec
                        Finished in 10 hours, 29 minutes and 47 seconds
                        (Render settings: 1200x1200 pixels, preset "16. Path Tracing - High + AA 0.3")


                        Thanks, again, Eric, for your help & contributions.

                          I've seen a stereoscopic SU/GE model of Machu Picchu (within this forum,) but haven't seen any stereoscopic renderings.

                          Has anyone pursued stereo rendering? (I'm thinking this model should make a good subject.)

                            Just a try for a quick benchmark test of my father's new PC!
                            A quick studio setup with two rectangle lights.
                            Took about 40 min (800*x) in vray. Thought it would be faster.

                            Tomorrow I will try a glass material. That will give some nice caustics.
                            Also tried Jade, but I can't get that damn translucency thing to work in Vray.

                                If you have simple lighting in KT (like one or two lights) then path tracing progressive might be the best option. Biased rendering will loose it's advantage when scene complexity rises and you use higher photon mapping options... For complex lighting MLT or MLT/BPT are better options. If you using HDR sky for lighting (and emitters), MLT might be the best option.

                                  That is great to know, as I haven't previously seen any recommendations about which render mode is best, under various scene conditions. KT has so many options, any tips/tricks are highly beneficial. If you've got any other such tips, or can reference KT webpage/forum URLs for such, I'd love to hear about 'em.

                                      Thanks, notareal, for the tutorial links. Now, all I need is a few weeks/months to read & apply it all.


                                      My last render pleases me above all my previous renders. The more I stare at it, the more three-dimensional it looks. (Who needs those fancy 3D goggles, anyway!)

                                          Stereo: View cross-eyed
                                          Initial experiment with KT stereo-image production. View by crossing your eyes, until the two images superimpose in the center. (It will look like 3 images in-a-row.) Concentrate on the center image, until it comes into focus.

                                          I used SketchUp to produce two "scenes," which merge into KT as two cameras. (Getting the spacing is tricky. You don't want to overdo the angular separation. It is supposed to mimic the angular separation of your eyes, so camera distance is also a factor.)
