I would really like do add a shadowmap to an area light.
I mean this:
When light falls into a room, there is a shadow of a tree from the outside.
But i don’t want to model this tree, i only want to add a shadow map to the lamp that casts these shadows.
I tried this for my lightsources (area lights; i added a texture [vororoni crackle] to the lamp) but shadows are
- much too sharp
- not realistic
- and don’t become larger when an object is farer away than another one (i only think that, i didn’t prove that point yet)
What will i have to do to get realistic shadows without a model?
Or did i Just something wrong?
