i want to bake a Shadow through Blender for my Roofbars because without it looks crap.
It's like ui Shadow but only with dif.spec.over
Here is a Picture:

And i need it separately because not everyone uses that Bars. (i add just the Mesh to the different Variants then)
And instead of that black i just want some smooth Shadow Tex with Transparency - so it won't affect Skins.
How could i make this happen?
