Good suggestion to Epic:
Whenever you roll out a new major engine version, please make sure that the majority of the assets in your market place being updated to be compatible with that new major version. Otherwise, most people upgraded are left in a situation where most of the assets in the marketplace are not usable.
Also, I remember that there is a policy that assets in the marketplace should be required to be upgraded to the latest engine version within 10 days (or 45 days?), while after the rolling out of 4.10, it’s been more than 10 days, and even some of the Epic provided assets (such as InfinityBlade env and characters) are still only compatible with 4.9.2.
I understand that the UE4 is going free for development (which we greatly appreciate), but to build a healthy community that is as active as Unity, at least keeping the assets up to date would definitely help migrating more people from Unity.
I would even suggest that instead of forcing the original seller to keep the assets up to date, Epic Games might want to help make sure that the assets in the marketplace being up to date, so the original seller can focus on actually creating the great assets, without having to be exhausted by always having to rebuild/re-export/re-import stuff by themselves. It would definitely encourage them to put more stuff in your marketplace.
Just my 2 cents.
Thanks for the great engine and setting it free!
