When I render an animation with a scene that has artificial lighting the animation is way to 'bright' and looks a bit 'washed out'.
Is there a way of setting up the illumination level for the scene prior to rendering ?
I have included 2 images.
1 is a single frame render with the lighting effect I want to achieve.
2 is a screen shot of a frame of the animation.

Hi Rich.
I wondered if the problems I was having was something to do with that specific file rendering on my particular computer.
To test I started a brand new Sketchup file with new geometry and then ran through the procedures we have previously discussed.
Everything worked exactly as it should !
The brightness slider updated the brightness dialogue, a new render prompted for a settings update and rendered correctly and the animation prompted for a settings update and again rendered exactly as I wanted based on the previous render brightness settings.
I appreciate the time and effort you have put into helping me, it seems to me the problem is local to my machine and confined to the one file so I guess we could leave it there.

You can get the statistics dialog from our About Box, Statistics button, but it should be a right click on the Title bar also (in the rendering window):

I tested just changing the brightness with the slider, and my brightness change got saved, so I don't think the mystery is solved yet.

Hi Rich.
When I hit the button next to the brightness slider the dialogue shown on the attached PDF comes up.
Can't see the dialogue box you have shown anywhere !
If I right click the title bar I just get
Restore
Move
Size
Minimise
Maximise
Close
The default brightness, contrast and burn is 50 and for saturation it's 100 (brightness is not 0 as you mentioned)
When I reduce the brightness with the slider to 35 I get the effect I want.
Did the render, then imported the changes and rendered again , the brightness stayed on 35.
I then closed the render window and opened the animation. Imported the changes and sure enough the animation rendered with the same brightness level as the earlier render. Dont know how you check the brightness in the animation window but it looked exactly like the earlier render so I assume it was using the '35' value
Seems that the trick is to change the brightness level from within the dialogue that comes up with the button next to the brightness slider in the render window, then it remembers the settings ? for future renders and animations. Do you think that is the mystery solved ?

Try this, in the model that you sent me:
1. Render a scene
2. Change the brightness in the rendering window. Load the dialog to do this, the button to the left of the Brightness slider bar.
3. Load the Statistics dialog (right click on the title bar, or else from the About Box dialog) and page down to the Tone Operator section and see what the brightness is set to.
Here I've got it set to -0.36, darker. (0 is the default brightness.)
Then close the rendering window, and go back to SketchUp, and render it again, after clicking on Import Selected Changes on that dialog that appears.
Then check the Statistics in the new rendering, and see if the brightness setting stuck at the same value.
Is the brightness still set the same as it was when you rendered the first time?
Then close the Rendering window and go back to SketchUp, and start the animation.
And check the statistics (You don't have to wait till it finishes to check this. )
Is the brightness still set the same as it was when you rendered the first time?
Hi Rich
Tried as you advised
Started a new sketchup session and opened my model.
Went straight to NXT setup options / more tab / load factory defaults.
Closed the setup dialogue
Went to the animation tab and got the same dialogue as last time
as an experiment
I started a render and interupted it by going to the setup tab in the render window
I loaded factory defaults from there then resumed rendering
When the animation finished I closed it and THEN when I went to the animation icon I got the 'missing dialogue
I clicked on select all / import selected changes the started an animation
The animation started but was using sunlight - no artificial.
I paused this using the setup tab again and clicked the int ./ no sun
the animation resumed using the spotlights but it is still too bright.
Any thoughts
Regards
Mike

Reload those defaults, from within SketchUp, before you do the first rendering.
Then you should see that dialog when you come back to SketchUp, after changing the brightness in the rendering window, whne you start another rendering or animation or when you load the Options dialog in SketchUp.
Try that.
Hi Rich
Followed your instructions but can't seem to get the dialogue box with import senlected changes to show up.
The attached PDF will explain my steps.

Got it.
At first the animation was washed out as you were getting. Then I lowered the brightness and ran the animation again to get an animation that was not washed out, with the brightness lowered:
1. Render a scene.
2. In the render dialog, lower the brightness to get the effect I wanted.
3. Close the rendering dialog
4. In SketchUp, click on the Animation toolbar button. You should see this dialog first:
5. Click on Import Selected Changes to keep the new brightness settigns that you made in the render window.
6. Then run the animation and it should render at the same brightness settings as you used and "Imported" last.
Try that.
