+To use the Projector/Light and Projector/Shadow shaders properly:
+
+Cookie texture:
+	1. Make sure texture wrap mode is set to "Clamp"
+	2. Turn on "Border Mipmaps" option in import settings
+	3. Use uncompressed texture format
+	4. Projector/Shadow also requires alpha channel to be present (typically Alpha from Grayscale option is ok)
+
+Falloff texture (if present):
+	1. Data needs to be in alpha channel, so typically Alpha8 texture format
+	2. Make sure texture wrap mode is set to "Clamp"
+	3. Make sure leftmost pixel column is black; and "Border mipmaps" import setting is on.
