The way we intended our “Subscription/permanent” license to work is:
- while you’re paying us, you get access to the latest Datasmith, support, assets and special learning
- when you stop paying us, you continue to have access to the last Datasmith you were eligible for, but you will not have access to support, assets and special learning
Right now Datasmith is only matched to an engine. You cannot use Datasmith 4.19 with UE4.20. I expect this to remain the case due to the large dependency Datasmith has on the engine.
So, if you stopped paying us during 4.50 release, then you could continue to use 4.50 release as long as you want, but you will not be able to use Datasmith with 4.51 unless you get back on subscription.
It’s really not subscription since you’re getting permanent functionality, maybe it should be called, “a more friendly subscription”.
