Currently working on a new project, I am trying to achieve an overcast, cloudy setting in my exterior rendering with soft shadows and no direct sunlight.
When I reduce the Sun intensity to achieve soft shadows and the overcast look, the trees lose contrast and shade under the leaves.
Check out these examples with sunlight:
You can see the trees have shade under the leaves and enough contrast. Now compare that to these:
Even when there is no direct sunlight, trees are still supposed to have shade under the leaves. Compare the trees to the black car, which has dark shade (not shadow) underneath. Am I doing something wrong or is this Enscape's problem? I'm rendering on Ultra. I believe this has to do with the fact that the sunlight passes through the leaves on the trees and gets transmuted ("Foliage" material). As a result of that the underside of the trees get 0 shade/contrast. How can I fix this? Post-production does not fix the problem because lowering shadows or increasing contrast affects the whole scene.
Here's some overcast photos for reference. Notice the shade of the trees has uneven lighting and darkness.
