		+	=== Point Light with a cookie/cubemap is black ===
		+	Note that Bakery supports colored cookies and reads RGB from cookie/cubemap textures. Unity, on the other hand, only supports grayscale cookies. Setting Texture Type to "Cookie" on the asset will convert it to a single-channel A8 format. For Bakery, leave Texture Type to Default.
