Whenever I have reflections enabled when using the Deferred Technical Preview, everything on the screen starts to visually glitch out.
Steps:
Enable Render Dragon Features For Creators
Install and Enable the Resource Pack
Switch to Deferred Technical Preview
Turn on Reflections
Expected:
The reflections and others to render correctly
Observed:
I cannot describe it in words, see video below.
Attached is a file of the pack I used and a video of the issue.
Note: not all PBR enabled resource pack is affected by this issue.
After further testing. I have come to the conclusion that this report is, in fact, INVALID.
The reason is because the pack I was using may have been outdated, or lacked the scripts or json required to handle reflections, which ultimately resulted in the strange artifacts shown in the video. I'm now using Poggy's Luminance Dreams PBR pack, and everything works fine. I'll be sure to use the latest pack version when a future deferred technical preview feature comes out before I determine if there is actually a bug or not next time.
