Hi guys,
I played around with the image map shader and read a lot about it in the forums. I thought I learned enough about it to start my first try... somehow I missed something, I guess.
I positioned a cam(topoCam) straight above the terrain (-90°), rendered (800x600) and modified it with photoshop to mask certain areas (black/white). The attached image shows the mask of the shoreline.
I plugged the image map shader into a surface layer, set the projection type to "through camera" and assigned the topoCam as projection camera. Somehow the result was not what I expected. I played around with the size and projection type without success

Unfortunately I don't know which size my terrain-file has, because it's a really old one from my TG0.9.
Any idea guys?
