2D Point Light problem.

Hi everyone,

In my 2D game i have:
Black sprite with "sprite/diffuse" shader.
When im put on it Point Light, im getting these ugly stripes.




I red that Point Light must be in baked mode, so when im tick on baked mode it says that Baked GI must be enabled, if i enable it and press "Generate Lighting" - Point Light stops emit light and my sprite become just black. All this going with Compress Lightmaps unchecked.

Can anyone help me to clean forever these stripes? )
