So when I was playing Kingdom Hearts 3 and I was watching the Frozen "Let It Go" sequence I noticed a weird thing pop up for a quick second before going away. At first I thought it was just my tv so when I was rewatching the sequence on YouTube to see how close they got to the movie I noticed the weird thing pop up again.
So I work professionally as a 3D artist and I knew exactly what was it was a watermark for a rendering program called Arnold and it usually doesn't show up unless you don't have a license for it or 3D program you are using can't access the license. That's usually a bad thing to not catch because it means there are other frames that probably have this watermark on there as well. I just thought it was funny thing to point out.
