Yes, I will be making textures for games as well as other 3d art, also
your method worked on layer masks and not the alpha channel, making it
unsuitable for multiple layers with layer masks but I can still use it
and you have my thanks.
This next part is to better outline my problem and way I solved it
with your help but first, the only problem I can see with your method.
For example, if I were to make paint in a new layer on some tiles that
had the bump map in a layer mask or alpha channel I would use a layer
mask for the paints transparency, and GIMP will alter the alpha
channel to include the data of this new layer mask and add a big white
area to the alpha channel equalling maximum height on the bump map.
To avoid this I had to store the bump map in a fifth channel to edit
it directly and/or apply it as a layer mask after merging all visible
layers to edit it using your method in order to transfer the data to
the alpha channel.
Hopefully an easier method is found or if the ability to view and edit
all channels directly is added in a future version of GIMP.
