As you see here the shadow of the tree goes trough the grass platform. I want the shadow to just appear on the grass. The grass platform has shadows turned off. Is there a way to make the tree’s shadow not go trough the platform without turning shadows on, on the platform?
You must remove the humanoid from the models in order to fix this issue. Humanoids will typically show a shadow through parts, and is something that happens with all humanoids on any type of model. You can then use the “Cast Shadow” property (which you turned off) to get the same, or even better result. Ensure that you have ShadowMap enabled as well, in lighting.
If you cannot see the shadow in studio/in-game, it is because your graphics are low (humanoids will show even on low graphics, but the quality of the shadow varies).
