My only issue with 4.17 is quite poor tracking. Which on the other hand will do as far as testing is concerned. I’m eager to actually release something for iOS ARKit therefore can’t wait for 4.18.
I’ve managed to get simple actor/objects spawn as well as whole levels. The camera texture didn’t seem dark for me. And haven’t tested mobile hdr that much tbh.
Based on the stream from Epic last week we can expect alot of improvements to ARKit.
