Hi Yashuai, I can't work out what you specifically mean for a read through of your email. It sounds like part of GeometryTechnique does support all the possible combinations of the image layers. I have a ton of emails and other work to get through today so can't head off looking at code in the off chance that I might be able to work something out. Please feel free to adapt the code to do what you need to do, and any mods please just post to osg-submissions so I can review and merge it.
