This is a serious bug/oversight on Adobe's part for a renderer! Need ACES color management support (see 2nd screenshot), or at the very least post effects tone mapping, & color profiles (see 1st screenshot below), like Substance Painter!
This is VITAL. There is not currently any way to acheive parity in how things look between Subsance Painter, and Stager without it. Everything is completely flat and washed out in Stager VS. Painter. Makes using Stager to render absolutely USLESS for anyone that uses ACES, or color profiles and post effects tone mapping in their Susbtance Painter authoring workflow. Please fix this as soon as possible. Thanks.
