I am trying make an interior rendering using UDS and I have a static mesh object from Megascans (from a Gemstone pack). It is a sunset scene with half of the frame is shadowed and half is lit by sunlight. However I realized that this genstone pack is always receiving the sunlight no matter it is placed in shadow. here is a screenshot. I also added basic cubes to better illustrate that only half of the scene is actually lit.
can someone help. thats quite annoying
