Our game is mostly based on mk4 stuff. We own all packages from Mk4 and we are using them quite a lot:
But in this case we replaced Mk4 models, because we ve got better ones. All Mk4 vegetation is based on Unity tree generator, but this tool in now becaming obsolete.
Yes, we are using some of them, it is not big problem to convert these assets into Unigine (or any other engine). Previous version of world was based purely on these assets. But now we are in process of replacing some of them with even better ones (much more detailed mesh, higher texture resolution, various performance optimizations):
