Help! Rendered Animations

[ashscott]

The only windows are perspex roofing lights and the client has specified that they don't want a feature made of them. I've heard the word global illumination before...will this help or have I mis-interpreted?

[Chris]

Global illumination is built into pretty much every Twilight preset. Basically it means that indirect light contributes to the lighting of your scene. So sun shining through a window into a room will illuminate all around the room, even if it doesn't have direct sunlight on it.

If this is indoors, I'd suggest omni lights where you'd expect to place lights normally. But that's definitely not my expertise. Maybe someone else can give good, but fast, lighting suggestions.

[ashscott]

When you say Omni lights do you mean point lights etc?

[Chris]

Yes.

Cool thanks for the help guys, much appreciated

On a side issue, has anyone ever encountered this problem with getting light speckled textures in a building?

You may want to try the "Animation" render settings on this scene! They will likely avoid the "sparkles"... but render times will go up a little bit.
The Light Through A Window thread, may help explain some lighting things...

and just created this thread which may help explain some things about render settings...

Thanks very much for the help Fletch, that lighting info will be great.

Hey by the way, I have 2200 frames to render in an animation, set at 'low' each frame was initially taking a minute or two to render. I thought I would have my render done by the deadline quite easily. However, I have gone away and expected to come back to an almost complete render but the render time per frame has jumped up to over 5 mins per frame, there is no way I can make the deadline at this rate. Why was there a change in frame render times? Is there anything I can do to amend?

As always, any help is much appreciated.

BTW it seems to be the antialiasing portion of each frame that is taking the most time.....
