Don’t give up … I also hacked around with Helixvision for a few days … until I found out that I mistakenly copied the mod with vk3dvision without the main folder into the game directory of Doom Ethernal …
There are also enough Youtube instructions from the modder “Helifax” … eg a profile has to be created for Doom Ethernal in Helixvision … and Helixvision has to be entered in the vk3dvision ini file … but everything is in the readme instructions …
It also took until Helixvision was running with my VR glasses … only the one beta with the “c” is allowed …
Much luck…
The last two Wolfensteins can now also be played in G3D with vk3dvision …
Look fantastic too … !!
