Work in progress, lighting problems

Anonymous — Thu, 11 May 2023 11:42:38 GMT

Hi everyone,

I'm having problems with a rendering. I want a nice lit picture (facade especially) but i also want soft shadows. So i turned the ambient light strong and the sun a not so strong. I thought that would do the trick... But i'm not so satisfied with the result, suggestions anyone?

In view of the fact that there has been several days for others to reply, I feel obliged to step in, but since I am also tiring of saying the same things over and over - things that reside in my book, I'll just list the issues in point form for you to search other postings:

Realistic sun - increase divergence for softer shadows

NO SUCH THING AS WHITE: give sun a color

NO SUCH THING AS WHITE OR SISSY BLUE: give ambient a proper color

Don't adjust LightWorks Effects Dialog Ambient until Sun Dialog Ambient is 100% - a waste of time.

Look up "Undersun" to fill shadows from below

Add skylight - a proper color

Come to my seminars in two weeks:

Washington DC, Philadelphia, New York, Boston.

My 2¢...

I don't find the solid brown massing elements on either side to make an attractive frame. As foreground elements they should either be detailed, translucent or just go away.

Right.
Why waste pixeltime on such ugly framing?
It also just pushes the detailed subject farther away from the viewpoint.

This is usually the place for winsome female figures gazing admiringly at the building.

Or hoodie-clad teenaged boys on skateboards if you want to give an overtone of street theft.

The reason there is this 'ugly' framing, is that the picture will be placed in a picture (taken on-site) where two buildings are on both sides of the path 😉😉 so that explanes why those are there. So it's easier to fit the actual photo.

And i try to use your book as much as i can Dwight, except. i'm working with Archicad 10 now...and i wanna use the real sun function. But this guy (me) never got the supplement for your Lightworks In Archicad 10. I've got the book for Archicad 9. And in 9 there's, as you know, no REAL SUN!

So...i wanna know good settings for Real Sun in archicad 10...

But for the record, i do use the hellezon.
I gave sun a color
Ok, maybe i gave ambient a sissy color
And i'm combining it with the real sun..( but don'y know how).

If my boss likes to pay, I would love to go to Washington DC, Philadelphia, New York, Boston 🙂

OR... winsome female figures gazing admiringly at hoodie-clad teenaged boys on skateboards... for a whole different story (fantasy?).

Phew, glad to see the full picture. That's what I meant about more detail.

Now I have to say that the woman in the foreground is a bit dominant.

Too bad you missed me in Eindhoven.

I am sending the link to you by Private Message for the Archicad 10 supplement.
Look forward to the 11 supplement later this week.

Perhaps we should avoid fantasy.

I was there in Eindhoven, we had a conversation about brick walls...using the archicad shader or an alpha channel mapping. I'm still using the archicad shader by the way, cause i don't need close-ups of walls.

Anyway, looking forward for your mail about 10, and thanks!!!

I didn't say anything about chains and leather.

Well running out of time... i'll post the result tomorrow. Dwight, i couldn't import your link yet, cause we have a blocker on our server, therefor i havent used your acad 10 tips yet. So i've done the ACAD 9 way.

I'm keeping my fingers crossed and hope in the morning there will be a great image, hahahaha...

....Here it is...(it's hard to get any depth behind the glass panes). But with time running out, this is the result we came up with.

Looks good.

I wonder what the foreground chick is looking at.
It is just out of the frame.
Probably something a dog did.
"Just watching my step…"

This is nicely composed.

If you had more time you would try to emulate the beautiful golden Dutch sunlight and blue skylight.

Thanks Dwight,

I still have a question. Do you place your people only wit PS? In this rendering most people are rendered as well (alpha-people ) but i'm not so pleased with that, i had to alter them in PS as well.

Another point is the gallery on the first floor. I wanted it to light out, but i find it hard to let the light behind the windows to stand out. When rendered without the glass, the walls are nicely lit, but with the glass it really flattens out and most details(*) are gone. Did you ever encounter this problem?

(*) the detail consists of a brick wall with portals with behind a, wall with a shop-facade-material (flat wall). I,ve curved the wall, so i thought there would appear some shading at the top and lighting at the bottom, but allas..

Figures in computer renderings are poor because they are difficult to match with rendered models. Because of this problem, I exclusively place figures with Photoshop. Since i consider each viewpoint a composition, I wait until the scene is composed before adding figures. Its art.

If you want wall effects, you've got to apply lighting artificially to get those effects. What you want seems distant from the camera - hard to show at a distance.

Remember my lecture about glass - keep it artificially transparent and artificially reflective and your renderings will work better.
