The Megascans library is now completely free for use with Unreal Engine.
That means that if you are using Megascans with UE4, you get free, unlimited, and instant access to all of Megascans through Bridge and Mixer, and a wealth of Megascans packs on the Unreal Engine Marketplace. Ten high-resolution packs have been shared today for free on the Unreal Engine Marketplace, with additional asset packs being made available for free on the Marketplace at a future date within the Unreal Engine 4.24 release timeframe. This way, you can access the content in whatever way you prefer.
If you’re using Megascans only with UE4, we’ll refund all of your subscriptions for 2019. If you have an active subscription, log in to find out how to obtain a refund. If you have made Megascans purchases in 2019, but do not have an active subscription, we’ll reach out to you regarding refunds.
Megascans subscription prices lowered for everyone
Furthermore, with the generous backing of Epic, we’re immediately slashing the pricing of Megascans, giving you nearly twice as much content to download, and removing the resolution cap—for everyone, regardless of what engine, DCC or renderer you love and rely on. We’re also giving you a refund for the remaining duration of your subscription period to allow you to hop onto one of our new plans. If you have an active subscription, log in to find out how to obtain a refund.
Bridge and Mixer 2020 will be 100% free for everyone
But that’s not all. Epic is helping us make the upcoming 2020 versions of Bridge and Mixer 100% free for everyone, with no subscription required and both fully featured. We are releasing these new free versions within a few weeks from now and I’m thrilled to finally be able to share with you the upcoming updates.
Most of the sources I've seen say "acquired", implying Epic bought them (example: venturebeat). Given Epic's strategy of getting people on their store, I highly doubt they will share with anyone.
Well that's not what they said in this announcement. They said their assets will be free to UE4 devs but still available to others, and some other features have had their prices reduced, so all in all it sounds like it's good for everyone but much better for Epic than anyone else, and it time that may lead to a bunch of competing asset libraries... which seems like a lot of overlapping effort for this market.
