Hi Chris Boyton,

Using AS 4000 V10 and up there are two different places to adjust the sun / shadows settings
1 - The GSP power tool where you adjust the settings of your location / time of the day, etc
2 - In the Liveview screen--> clicking on the sun icon (lighting) you can set the sun position, angle etc

Now, if you set the sun position and angle using the option # 1 and immediately you render your image in liveview, the shadows will be exact for that location, time etc. But if, after you set # 1, you make changes using option # 2, Punch will use # 2 instead of # 1. In other words, option #1 sets automatically the parameters of the tool mentioned in option # 2

There are some elements that prevent the shadows' generation
- If you have a Photoview image in front of the sun
- Some topo entities (for example, an excavation)

If the above items don't solve the issue, send me your file and I'll check it
