I downloaded a model from 3dw and rendered with "Display shadows" and "Use sun for shading" turned on. The render is too bright. Is there a way to reduce the brightness. I already have "light" slider at 1. Please help.

Yes it is. Podium "listens" the dark slider not light. So decrease the dark slider.

I'm getting the same problem ! 
I try to render an interior scene, so I'm using interior_preview.pps. My light settings in SketchUp are 33 light/dark and almost the same thing in the Podium preference pannel. Even with the dark at 0, I get a shitty render. We are a couple of students who get the same problem. So thanks for help !

Ah - you have found an old post from 2009 relating to the old version of Podium.

V2 doesn't use the SU light/dark sliders at all. You need to move the sliders in the Podium dialog. Try moving them all the way to the left.

If your scene is still too bright, use the default preset

Aha - I think the results of the default preset are pretty cool!

Sure it is, but I'm not sure to understand where the problem was....? Even the high settings produce a weird result. It is a known bug ? Should I reinstall SU Podium ? Cause I tried different things, like restarting sketchup, or creating a new model, or even changing the textures, but the light problem was still there.

The thing to realise is that the presets completely configure the render output. 
The range of brightness is hard coded into the presets which means that for most scenes, you should get good results with a single click.

What you have here is that you have an atypical scene in that it has lots of openings and pure white walls. The interior presets are intended for scenes where the windows aren't too big, and the lighting levels need boosting.

For scenes like yours, this means that the renders will be overexposed with the usual interior presets. The default preset should kind of work for interiors and exteriors. Exteriors will generally be a little bright, and interiors will generally be a little dark. For scenes like yours, it's perfect. W have the same thing with clay render mode. Sometimes we have a particular problem with clay render mode with exteriors. For these we need to set sun brightness and exposure to their minimum values. 

Preview presets mainly remove the antialiasing stage. The high presets only enhance the antialiasing. If you don't verge very fine details, you genuinely won't notice any difference apart from what might be a substantial increase in render time.

Hi again,

I'm experiencing the same problem, but now with an exterior scene. With the lowest light settings, both in SU & Podium, with exterior.pps, with default.pps... I get an over-exposed render. I tried with physical Sky instead of SU background, same result.

Te image attached was my sketchup exterior scene with SU light at 0, Podium intensity & exposure at 0. I don't know where s**t hit the fan...

Overexposed? This is nowhere near overexposed.

Have you look at this? If not please do, if you still having questions after, I'll be more than happy to help you.

SU light settings have no influence on the render, only time and date will (plus PDM Intensity/Exposure sliders). On the other hand, you are showing us a render (which is not overexposed) without the physical sky with a solid white sky, so that's a bit hard to comment.

Show us renders with the physical sky, the results are really different and it will be easier to guide you!

I have the same problem with exterior render too bright. I have read the "Troubleshooting" page and fiddled with the setting for hours. I finally pushed both sliders to the far RIGHT and got a much better result. I wonder why the sliders have no corresponding percentage number. This seems to be an interface oversight. Other sliders DO (in Materials, for example). I have several other interface-related questions I'll post separately.

If your renders are too bright and you push the Podium Sun Intensity and Exposure brightness all the way to the right, you increase the brightness for any given preset. It's impossible to reduce the brightness if you move the sliders to the right.

If that's what you think has happened, you've changed the preset.

The reason the sliders don't have a percentage attached to them is that these are modifiers with a fairly narrow range. They are relative not absolute values and their effects vary from one preset to another.

"If that's what you think has happened, you've changed the preset. "

It sounds like I would have to open the preset in a text editor. I have not done that. I did change some of the checkmark to the right, if that's what you mean. 

I did more tests and had better results with the "default.pps". I'm now going back the the "Exterior" presets to try to understand how to make them work for me.

I am also confused by the "OK" "Apply" and "Close" buttons in the SU Podium interface. What is the real difference? The OK button also closes the dialog box. I just clicked "Apply" in the "Materials" dialog and SU bombed. My experience is that rendering software tends to make SU less stable.

I also wonder how to save settings for specific files. It appears if I make changes to SU Podium settings in one SU file the same settings are transferred to other files. Is that correct? I don't see a place to say "Save settings".

V2plus is in beta at the moment so there are some issues with stability in SU 2013. We are working on it and have solution. Untill that, don't change values or click apply in Podium options and materials windows unless you have closed Podium rendering manager in the background.

If this is incovenient for you, you can always roll back to V2.11 which is more stabile.
