hey everyone,
I would like have an advice about a topic that really struggle me.
I’m looking for the realism in architecture visualization but i cant’t reach it. I Know that it isn’t only a question of chose the right set up of lights, matherials but also good composting and good color grading.
i post this two images just for and external point of view and maybe have some advises.
In conclusion, don’t you think that 3ds + corona is more precise than c4d + corona ?
Is It just my opinion ?
I mean is very hard find out good images with c4d corona…or it has just less users…
always an interesting topic “what makes renders look real” ?
From my personal experience:
lighting, lighting and again lighting.
“A bad photographer cares for his gear, a mediocre one for the motives, and talented ones care for the light”…
Be aware… in beautiful and natural lighting, even an empty room will look great and will have ATMOSPHERE.
daylight is not generic, like the sky & sun system in 3D-softs ( they are okay for some purposes)
daylight reflects colorful light from blue sky, orange sun, green grass & tress, etc… so, use HDRs !
physically plausible materials (IOR, gloss, etc. )
objects that are according to real world ( size, proportion, details, etc)
avoid “perfection” - means: in reality NOTHING is really perfectly clean, straight, etc.
apply imperfections and variations in reflection especially on floors, furniture surfaces, glass, etc.
don´t exaggerate with contrasts but also avoid a “grayish” light & color mood.
try to make it look like we see reality… not over-artistic and with those typical Arch-Vis dramatic moods that looks like total composting… except your client likes it… or you simply want this mood…
Of course, if the render engine doesn’t calculate a natural lighting… it´s bad.
But Corona really DOES calculate a very natural light behavior.
Regarding your question about 3DMax and C4D…
As a C4D user… especially during the pre-release phase of Corona for C4D, I noticed big differences in light calculation compared to Max.
But meanwhile… I would say they are minimal.
I have been following Angelo Ferretti from a while and i love his images.
Designerman77 “1. lighting, lighting and again lighting.”
Totally agree, and thanks for the advice.
Anyone Knows Where can i study lights set up and composition for each situation (exterior, interior, natural light…and so on) ?
I mean some courses (online courses) or books…
In the images i posted, I’ve used really flat Hdri for the sky and Corona’s sun, than Lightmix in post.
regarding HDRs, I prefer 360° HDRs, instead of those which have only the sky dome - especially if you don´t build up a whole 3D-vegetation surrounding.
Because the 360° will give you much more natural light colors in interiors ( and in general ), due to the ground surface (grass, etc.) that will reflect onto your walls.
Use HDR with a “moderate” sun position… not 12:00 mid-day… but something like 25° - 50°. So it will still generate enough energy into deep / long stretched rooms,
not only a hotspot near the windows.
Take HDRs with not too blue sky, but a balanced color, some haze and tender clouds, that diffuse the light. Of course you can apply a filter and tweak the colors or play in the camera settings, etc.
Play with the gamma of the HDR, if you want more contrast, color and sharper light/shadows… (reduce the gamma a bit).
Have a look at your rooms in reality… the “white” walls are actually totally colorful if there is some vegetation or buildings outside, that are not all grey…
One thing that I TOTALLY love about Corona light calculation: when light comes through a window, it will be split into spectral colors when it touches the edges of objects.
Sometimes you can see this quite clearly. This optical effect exists in reality - and especially in renders with lots of white walls & objects, this makes the scene look very natural and real.
Regarding your question, where one can study lighting techniques… I didn´t investigate that topic on the net so much…
But simply purchase some nice scenes… like from Angelo ( I don’t know him personally, neither advertise for him ! ).
Study his lighting technique and try to develop your strategy out of it.
Some small “hints” from other experienced 3D artist are often enough.
Then it’s simply about doing it - let real photography & illustration be your Imaginary Muses! Since CGI is merely a virtual medium (transferring an image from mind into light & matter). It also helps to take art photography lessons, attend workshops, but foremost: “Communicate with surrounding by paying attention to detail.”
