Alpha bitmaps are used to define which areas of the bitmap should be visible and which transparent. White indicates a completely visible and black a completely transparent pixel. All sorts of greys are something in between. So basically you need to make a version of the bitmap that has black where you want the actual bitmap to be transparent and white everywhere else. When I save the alphamaps, I usually just take the original bitmap name and add a prefix 'a_' so it's easy to keep track of the alphamaps.
I think that the alphamap still needs to be 24 bit bmp, even if it's greyscale (8bit). I'm not sure though.

Then you must define it in the menu.ini with line
images=image# bitmapname alphamapname

Thanks heaps for that info! I understand it now. BUT! I've got a problem... I've made a custom crosshair and I want it to be semi-transparent. Is this possible? If so please exsplain how. I've already tried a grey alpha map and one that fades from black to grey. The grey one doesnt work because the crosshair is still fully visible and the other one doesnt work because its completely invisible. Thatnk you sooo much if you can help! Heres another couple of screenshots!

And finaly (sorry to make a new post) The lift leading to the second level!

These screens are just amazing! Very very good desighn! I also love that there is a bit of variety to it...

Im sorry but im not sure why your crosshair is not working, Im pretty sure semi transparent crosshairs are possible but I thaught that it would just need a grey (darkish grey) alpha map...

Thanks for trying to help... It's much apprieciated!
