Cubic environment mapping not working

[Goblan]

I'm running the game on Windows 11 + dgVoodoo. I find cubic environment mapping's not displaying. In fact, no reflections are displayed at all on the player's car when Cubic is enabled. I've checked a few videos on youtube: some people have that issue, some don't. I have no clue what the reason could be.

Anyhow, I'm getting the expected performance drops, so I guess cubic reflections are being calculated and all, but not displayed, for some reason.

Any help would be much appreciated.

I'm also experiencing this, but I noticed that if Cubic mapping is on, there is a grey "square" artifact in the upper left corner that changes shape as you drive around, so I think that's where the reflections get drawn to for some reason (as opposed to being applied to the car).
