Hi all,

So I can see that it's pretty straightforward to set object transparency when you want it to be totally on, totally off or read the alpha data from an external texture with an alpha map, such as a PNG file...

Yes you can do it. Make sure that transparency is on using SetObjectTransparency(). Then use SetObjectColor(object, r, g, b, a) and change the alpha value. Unlike sprites, you can't change just a single colour at a time so you have to use a type to hold object ID and colour information and set all colours at once. I usually have something like this:
