(Note: the following were steps from a UDN, but I can easily reproduce the issue on my end, as well)
Make sure to have a bk2 file and a corresponding Bink Media Player asset ready before using the steps below to reproduce the issue.
- Create or load a level that you can play in the active level editor viewport.
- Play the level (using the green arrow button) to launch the level.
- Notice everything is fine.
- Stop the simulation.
- Open your Bink Media Player asset from the Content Browser.
- Make sure the setting Bink Draw Style is set to Overlay Fill Screen in the Bink Media Player Configuration Widget. I attached an image to show the settings I used when writing these steps. Save your changes if any where made.
- Play a few seconds of the video and pause on any frame that you can easily recognize.
- Close the Bink Media Player Configuration Widget.
- Play the level (using the green arrow button) to launch the level in the active level editor viewport.
- Instead of seeing the level like you did on step 3 you should see the last frame you saw in step 7.
- Even if you load a different level you will have the same problem you did in the previous steps.
- The only solution I found is to simply close the editor and re-open it. Otherwise the frame is stuck there forever.
