I am making some tests with the EU 4.19 Preview 4 version and the new command “vr.PixelDensity”, It work pretty good but I have an issue with the compiled version of my project, the picture is clean on the HMD but I have a weird effect on my PC monitor :
Basically you need to create a simple scene and upload it, also you have to describe steps to reproduce the bug. Then it will create a ticket and post it here so everyone can VOTE to fix it. Also please don’t forget to post ticket-link on the main UE4.19 Preview thread.
