I never kept the xcf for the text I used for the banner but I did find this old one. It may help to see how I set out the layers.
The Gift layer is the basic text layer after the lighting effects have been added to it. Mode is normal opacity 100%
Structure layer is set to soft light opacity 100% It has been desaturated
Rift layer normal opacity 100%
Rift copy set to dodge opacity 100%
Rift copy #1 set to dodge opacity 100%
Rift copy #2 set to grain merge opacity 100%
Visible layer, a copy of visible, is set to dodge opacity 100%
The layer called Layer is the original text layer before the lighting effects were added, It's a matter of choice as to whether it's turned on or off.
The rest of the layers, not enough room in the screen shot to show them all, were for the light ray effects and were a total disaster. I never could get them to look right.
