Thank you for the reply (and the information regarding the outline). I had to tick the checkbox marked "Alpha To Coverage" as well in order to see an actual transparent texture. I have another question regarding what namespace gets generated from the shader, in order to access the alpha value through script. This thread says "pay close attention to the namespace", but in the example HighlightAnimated.cs mentioned, I can't figure out where the exact namespace string can be copied from: http://amplify.pt/forum/viewtopic.php?f=23&t=374 The shader name in the editor is displayed as "ASESampleShaders/Community/TFHC/Highlight Animated" but the namespace is "TFHC_Shader_Samples". What am I missing?
