light cast problem

Hello
I have a big problem, look at this

I can’t understand why?
I used a same material for rock and ground with different texture, but i can’t see cast of light on ground(ground isn’t terrain).

*quality is good and android platform

sorry for my weak en language::.
and thank you

Are you aware of the max-point-light-limit? Depending on the quality settings it’s 1,2,3 or 4 afair. Another issue could be that your vertex-normals are pointing the wrong way.

The last thing i would check is the layer settings of the light and the ground object.

If it’s a static light you might want to bake it into a lightmap instead.
