I always do that
Have you launched the texture arrays editor yet? If not please start UE_4.19_TextureArrays/Windows/Engine/Binaries/Win64/UE4Editor.exe. That should add it to the engines list, allowing you to choose it when right clicking uproject -> Switch Unreal Engine version.
Could you copy those errors to a pastebin?
If it still doesn’t work you might want to join the discord (Voxel Plugin), will be easier to debug there
@VariableArgument I can’t guarantee anything, but from what I’ve heard the MP team allow the seller to give some licenses for free. If you buy it now on Gumroad/Sellfy, I should be able to transfer the MP version to your account.
