Brian C. said: Joe said: If I’m remembering correctly some marketplace purchases do this already (eg map tiles), which means it is supported in some fashion, but I’m not clear on the details. If you are referring to what I think you are, those are add-ons with fully set up map pages. At the moment, outside of the API, there is not a way of tying the dynamic lighting lines to an image on another layer that I am aware of, but even that does not have the dynamic lighting built into the image, you have to associate the DL lines to the image after the fact. You are correct, I can find no mention of what I was describing. So this suggestion would be a definite improvement.
