Weird rendering issue on packaged game

Hello everyone,

We have been participating in the Epic MegaJam with our game Yokai Hunter, it turns out that we have tested the builds on several PC’s and on all of them it worked great and looked perfect.

Here is the sample of what the game looks like when it is running well:

Recently a streamer who is playing all the Jam games has left us a comment where he said that it looked really bad and he was having graphical issues. He has passed me the link of the stream where you can see our game at minute 5:44:32, and the truth is that it does not look at all as it should look.

I have redownloaded the game and I have asked other people to test it on their PC’s and we all look fine.

Any idea what could be causing this problem?
