I have a problem with shadows on a curtain mesh of transparent material. DirectionalLight is set to static as well as mesh. UV map is spread over the first and second channel. I try to increase light map resolution to 512. Nothing has changed.
Have a look at screenshots.
Here also material details:
I think the mesh is not too havy. It has 10k polys.
What I want is a transparent curtain that cast a shadow.
Does anyone have an idea how to fix those ugly shadows ?
