no, there isn't one. i think it because the 8.1 base has different polygons in the mesh. in my eyes 8.1 is a different character, and with sellers creating products exclusively for 8.1 cements that even more so, a year from now the ratio of products for 8.1 that doesn't work with 8.0 will be a lot higher.
isn't there a way to make daz think the dialed character is using 8.1 even when it isn't?
Look at current morphs but make sure you unhide the hidden properties. I've had the same problems and they are all characters with their own unique expressions in its morph folder. For some stupid reason when G8.1 load a G8 head morph it will dial up those unique expression morph to 100% and hide it in the parameter tab.
