RT Enhanced Quake (vkquake-rt)

Hi everybody
i was wondering if there is someone interested in playing “Dimension of the Machine” on RT enhanced Quake.
i’m using vkquake-rt v1.0.2 ( sultim-t/vkquake-rt (github.com) 1) and playing Quake with RT is AWESOME.
i manage to finish it at Nightmare skill in a couple of days.
i manage also to boot (with this engine version) the enhanced episodes:
Scourge of Armagon
Dissolution of Eternity
Dimension of the Past
All flawlessly and with RT support.

But when it comes to “Dimension of the Machine” i got this error on starting up new campaign:

im still able to startup certain maps though (mge1m1 and hub for example) but there are some glitches and the same error will appear on hub map if i advance forward…
I downloaded and compiled latest vkquake sources and there is no problem with that but adding RT support is way beyond my skills.
i am hoping for someone’s help.
