I am trying to see how shadows will gradually be formed early morning on my model. This is important for planning the position of solar panels. The problem is that up until a certain time the modal shows a night vision with no sun and now shadows at all, and then all of a sudden one minute further the sun is completely in. This is different from the transition between day and night that is gradual.
How can I see the gradual transition from night to day?
I can’t reproduce this with SU16, can you create a short screencast?
@coty, I think the OP refers to the lack of ‘moonlight’ and a transition through dawn…
@Gilad, I agree it could be handled better if this is what you mean…
a 24hr scale and building of intensity would be nice…
I believe that the Extension ‘LightUp’ can do that… [but I don’t have it atm]
If you are doing daylight analysis and/or solar panel placement, to get useful answer, you want to account for:
- horizon cutoff at which point sunlight becomes useable (LightUp conforms to BRE 379)
- historical cloud cover for the location you’re planning (LightUp uses per city data)
- surrounding sunlight occlusion (LightUp gives Annual/Winter Probably Sunlight Hours)
- a physical sky model (LightUp uses CIE clear sky)
The SketchUp shadows are correctly located but as you comment, just a simple On/off affair.

Thanks for the heads up. Will get it fixed.
