Releasing a Blueprint

Hello,

I am looking to release a blueprint I developed in Unreal onto the Marketplace, but have one problem: the blueprint requires the free OpenCV Library in order to work.

Should I just leave the library in the submitted project? Am I allowed to sell this item that uses the OpenCV Library? Or should I just mention in the description that OpenCV is need to work?

I gather that OpenCV is a library that you went and licensed independently (rather than having gotten it from Epic). You can just report what third party software is used when you submit content for the Marketplace and they will let you know whether it’s approved or not.
