Under Skydome, I want to access Cloud cover and Precipitation Type in order to change weather parameters during simulation. Is it possible? I would like to seek and advice.
The simplest way is to create a string output in your python script, and connect it to the Sky Dome Precipitation type.
When you want rain, you just set the output to "Rain". When you want nothing, you set the output to "None". Just use the string that's shown in the combo box of the SkyDome..
Hope it helps,
