Light leaks

Recommended Posts

Hey Rich,

Please, post your GI WIndow and Photon lights setup..

EIAS 9 have a really easier Photons setup and have better GI + Photons + Reflections + amazing speed :)

 

Thanks

Thank you, Tom.  I look forward to upgrading!  I think I'll be able to very soon - a client is gonna pay me!

 

@@@

 

This scene has 2.9 million polygons.  It's illuminated by three lights.  A light object that covers the windows.  A light object

that covers the roof skylights, and a sun.   There are a few objects in here that have high reflectivity: the silver lamps,

the chandelier, the railing.  I had a nice glow working but it 

 

It renders pretty fast in v8 except when I turn on the reflections, then it slows down considerably.

 

Here's the data:  http://www.princetondigitalarts.com/eias3d-data.jpg

 

Thanks again,  Rich

Hey Rich!

 

Turn off the Parallel light and see if the Light leaks still persist.

Why are you not using Photon lights as “permanent” instead of “Always” for final renders, you will have a speed up.

Reflections are really optimized in EIAS 9 :) a lot faster !

 

Thanks

Thx, Tom!  

 

I am rendering now with Parallel Sun Light turned off.

 

When I switch to "Permanent" I am prompted to create a .phm file.  I do this for the two remaining Light Objects (the windows and the skylights).

 

When I run this, Renderama crashes with camera errors on all ten cameras.  

 

Should this "Permanent" .phm file be located within each Camera folder?  Is the problem that it can't find?

Ola Rich!

 

It will create inside the Project folder.. do a first render without Rama, then use Rama, otherwise Rama will try to send the phm file, but it doesnt exist yet.

 

Msg me

 

Thanks

Hi Tom!

 

And thank you again!

 

Yes, by doing a small render w Camera, I was then able to create "Permanent" .phm files for further renders using Rama.  Fixed.

 

I turned off the Sun and it's photons and the "light leaks" went away.  I then adjusted up the light levels so that the entire scene

was illuminated by two Light Objects, (1) shining through the vertical windows, and (2) shining through the roof skylights.

 

I have been able to re-introduce the hot spots created by the Sun, but I had to turn off the Roof Light Object to let it shine through.

 

See this:  http://www.princetondigitalarts.com/screen-shot.jpg

 

Is there a way to get the all three to work?  

 

Many thanks.

I think I got it...

 

I went to the Roof Light Object's "info tab" and the subtab "shadow" and turned off Cast Shadow and Receive Shadow...

 

The two Object Area Lights work w the direct Sunlight now...

 

Thank you very much!

 

If v9.1 is faster and better than this, I can't wait...

It is, really!

 

btw: nice renderings! How are the render times?

Thank you, Alex and Tom!

 

I have posted info here on render time:  http://www.princetondigitalarts.com/post.jpg

 

My render farm is a MacPro Nehalem w 12GB RAM and ten Cameras running.

This lighting looks pretty good to me, although I think I see one tiny light leak behind the statue

at the window casing.

Room dimensions are 110' long x 85' wide x 55' high ceiling. 

 

I was wondering how to make the hot spots less sharp, more fuzzy or atmospheric.  Maybe render the light only and adjust in PS?

It would be very cool to get shafts of light, as though light is colliding with motes and dust etc.

 

Tx for the good word.

I really like it!

 

With V9 you will get a speed bump that is tremendous!

 

An other thing is "one pass rendering".... I also always wanted

to do it in one shot, evan animations, but in reality i always have

to tweak a little here and there (PS for stills, and Motion5 for animation,

(ok, i am the only one using Motion, the rest of the world uses AE....))

to get the right look. Its often faster than to do millions of rendering

with different settings - my experience.

Ola Rich,

EIAS 8 will take one hour in your Camera, pay attention in the leafs, they are not clipped with GI.

As soon you activate to clip map with GI.. It will slow down a lot ;)

Thanks
