I've set up a PF_Param_LAYER and everything works fine so far, however, how do I actually set its value from within the sdk? The reason I need to do this is because within my plugin interface I have a button that will create a number of secondary layers for the user, which the plugin will then refer to via layer parameters. However, I don't want the users to have to manually set these after their creation, but rather just preset them with the correct (newly created) layers.
Looking at the parameters u.ld variables, I can't really find anything that could be set to something like a layer handle, id or whatever? So the question is: how do you actually set a layer parameter to a specific layer?
