Hi Jason, and welcome to the Forum.

You've posted your iClone/CC question in the "wrong" area - but that doesn't matter too much. The iClone/CC section is here.

Due to a variety of factors iClone character clothing has always been restricted to the "Base" version that it was designed for - G1>G1, G2>G2 etc. None of the G bases can use, or be used in, Character Creator assets.

The Public Beta of Character Creator 2 going on at the moment has demonstrated that all the clothing available for version 1.5 works without problems in version 2. The only difference being that 1.5 clothing does not have the PBR material maps available in ver. 2.

Most G2 through to G5 clothing bases "can" be converted for use within Character Creator, but it involves a lot of work - and a few other pieces of software to accomplish. The clothing items, Upper, Lower etc. must be opened in 3DXchange, exported as OBJ files and then imported into a software like Blender (free) to have the iClone bones transferred to each item using an FBX character file provided by Reallusion. This is very time consuming, and can even be frustrating, but the results are usable.

If iClone 7 is anything like iClone 6 regarding Character use then it should still be possible to use older generation assets without too many problems - I've used G1 Characters as background figures from my iClone version 2 in iClone 6, and even the older motions work quite well.
