A user has reported on salesforce that their RVT material is returning black. After following the publicly available Epic Quick Start guide online I encountered the same issue.
The ticket was reported on Mac. The black texture was reproduced on both Mac and Windows, however the crash was unable to be reproduced by UEQA.
I was unable to track the logs on crash reporter, but provided the callstack.
I've also attached an image of my workflow.
Expected Result: RVT renders as intended.
Actual Result:
1. Instead of correct rendering with RVT, rendering is black
2. When pressing apply or saving, engine crashes
3. Even testing other tutorials to generate RVT, the RVTexture asset is still black.
