For any hair assets purchased from the Content Stores you would need to purchase the Extended License version.
For our SkinGen packs, Realistic Human Skin, and Makeup & SFX, these are supplied with an Extended License for the Standard License price. Ultimate Morphs is also sold with an Extended License at the Standard License price. This means all these assets can be exported and used in commercial games without any further cost.
For the Headshot Plug-in the "Headshot Morph 1000+" pack is also Extended License ready. No additional costs involved.
And of course, all the embedded content that comes with CC4 can be exported for use in commercial games without requiring an Extended License.
I hope this helps explain the situation.
