Heightmapping coordinates don't work with scrolling

I've been trying to get heightmapping lighting to work with the mouse position, and the coordinates when the screen is at the top left are about mousex*0.00155 and mousey*0.002. It works until I scroll the screen, then the lighting gets misaligned again.

Is there anything that can be done about this?

You could probably add the amount of X/Y scrolling to the X/Y coordinates of the light. It should probably work.

Try (MouseX - ScrollXLeft) * 0.00155 and (MouseY - ScrollYTop) * 0.002.

Thanks, it works great!

Another question - where's the way to set the attributes to effects applied to a layer via an action at runtime?

Sorry if it's obvious and I can't find it...

Sorry, it's not yet implemented... on the todo list!
