Hi, using the new beta, I'm not sure if this is a known issue or not, but I didn't see it in the release notes pdf, but the newer feature of being able to change the size of arrays in shaders like Composting_select and Generator_blend_ramp and being able set the values of each array element in the parameter editor seems to be broken. For example, if I set a blend ramp to have 4 colors, setting the location to 1.0, the shader just blends to the second color, then fades to black above 1.0. This is the same for the select shader, putting the Selected Color value to 1 and above only selects the second color/element. Mapping the values to a Phenomenon doesn't seem to work either, nor does putting other nodes into the array's inputs. The only thing that seems to work, is setting the amount of colors explicitly, in the msl file.
However, this didn't seem to be a problem in version 1.0, where you could only edit array values in the graph, but it seems you can't edit the values in the graph in version 1.1 now. I was making shaders with different array sizes but, having the flexibility of changing the size in MM was pretty nice.
Thanks - Ian
