> Adding a new Color_Sampler shader should create a new source. If that's not what's happening then something's up with your install. I just tried it on a fresh install of 5.0, 5.1 and 5.1 SP1 and they all create a new source for each instance of the Color_Sampler shader.

> I’m struggling here a bit adding lightmaps to material. Fine with the first but when you add the second lightmap the image source is shared with the first making it difficult to change what the lightmap is writing to without changing where the first map writes to. Simply creating a new clip for the second lightmap isn’t enough because it needs a writeable image source. There doesn’t seem to be a method for creating a writeable image source so I’m a bit stuffed.
