Has one ever been converted from BF2 to BF1?
I've seen some of the models used in maps, but I recall that the full map was tried, but the collision errors were far too extreme to compensate for.
A map with collision errors can be memorized to know where the errors are. A few people are equiped to handle those types of maps. I love that kind of challenge. There are always soloutions. I can't wait for new stuff.
Pi Man was working on one, as was Battlebelk, but they were not released publicly. I think that there is some issue with the majority of the models not working that well and crashing the game.
