Shadow percentage

Hello all,

I am unable to calculate the percentage of shadow on my base plane, for the following geometry, the case is that it should be 50 % of the area(25m^2) of my base.
Or is there a graphical representation which can give me a numerical percentage.

Kindly share your knowledge.
Thank you for your time in advance.


You can pass the results through Cull Face component and calculate the are that sunlight hours is less then your threshold value. See this example on Hydra as a reference.
