Spotlight as flashlight in 2d

Hi,

I am tryinig to do a flashlight in a side scrolling project but I have a weird problem with spotlight: when its rotation is -90 degrees in Y axe, it iluminates like this:

But when I set the rotation of the spotlight to 90 degrees in Y axe (opposite), it illuminates in a different way:

Why is doing that?

Thanks!

I found the problem and the solution: I was using a “Bumped Diffussed” shader and looks like I imported in the wrong way my normal map. In the texture inspector of the normal map image, it has to be checked “Create from Grayscale” option and then apply.

Thanks for the help!
