From the EULA (I left out points 1 & 2, since they are not relevant here):

"Subject to the terms and conditions of this Agreement, User may (i)... ...(iii) publish, market, distribute, transfer, sell or sublicense User’s two-dimensional animations, renderings and other works; provided that User may not in any case publish, market, distribute, transfer, sell or sublicense any renderings, animations, software applications, data or any other product from which any Content, or any part thereof, or any substantially similar version of the Content can be separately exported, extracted or de-compiled into any re-distributable form or format. All other rights with respect to the Content and its use are reserved by DAZ and its licensors."

So apparently even the height maps are illegal to distribute, since there are restrictions that apply to 2D renders as well.
