Light problem

[Anonymous]

Hello mates!
I 've been seaching this great forum - but didn't find any already existing tread about it:

While rendering I have a problem with light source.
Lets take halogen lamp and put it in an interior. I will have the light that it give and bright room - but I won't see any light source (highier intensity light near the bulk).
The same goes with any other light source in ArchiCad 9.

Could you please explain me how to show the highier intensity light near the light source?

Best wishes and please forgive me my language.

Let me see:

the lamp is on and emits light, but light intensity is even, it does not reduce in intensity as distance from the lamp increases.


You are working in Archicad 9.
You are using the internal engine.
You are not selecting light falloff in the PhotoRendering Settings.

Or.

you are not telling the light to have "Falloff" in the lamp settings.

Or shadows are off.

Thank you for your attention Dwight!
Maybe the picture describes better what I meant...

There is no light source on the ceiling!

I see the problem.

The problem is that you expect room lighting from Archicad lamps to illuminate the space as you would expect, when the lamps do not perform as you expect.

First, your intensity is generally too high AND your surfaces are too reflective and smooth.

If i was a photographer, I'd bring lots of fill light (in the form of a General light source) and reduce spotlight intensity until they act only as props.

NO SUCH THING AS WHITE!!!!!!!!!!!!!!!!!
make your lamps all yellow-ish.


This is truly a difficult space....

Walls and ceiling are WHITE in my bathroom.
And it looks really DARK.
So I guess the intensity is not a problem here...

All I need is to have the lamp's bulks glowing --> something like a lens flare effect in photoshop...

Maybe another picture can describe it perfectly...

You want to show a light source. That's easy. Light sources are invisible.
Place a white disk right behind your light source. Make it have constant reflection.

You mean white circle ---> for example made of SLING?
Should I place it a bit highier?

[Dwight]

SLING?

I meant Ceiling tool...

I put such a disc 1 cm above light source and also behind it...
All I've got is on the pic...

What I'm doing wrong?

Once again thank you for your time Dwight

You'll never get glare like the photoshop flare...

This image is done with some diffuse glow in photoshop - the candle flame is light over.
