Using materials and meshes from official demos

I have a small question that I didn’t see in the documentation (I may have missed it) and was wondering if someone could enlighten me.

Are Unreal 4 subscribers allowed to use the materials and meshes from the various demos that Epic put out to demonstrate different effects like the “Elemental Demo” or the “Effects cave” in our own projects, especially ones we plan to sell commercially? I particularly like the flowing lava in the elemental demo and would like to use it, at least for a base of something.

Thanks in advance!

Yes, you can use them in your commercial or non-commercial projects.
