Hi, I want to put a simple sticker on a surface. I have created the sticker in photoshop and saved out an alpha channel.
I have projected the sticker graphic to the colour channel of a lambert shader.
What I want to do is use the alpha channel to mask out the white area of the sticker so i get a red oval sticker with no white.
When i plug my alpha channel into the transparancy rgb of the lambert, the alpha mask is stretched accross the surface geometry and not constrained to the sticker graphic.
I cant understand why this is happening!
Can someone please help?
