Missing Skybox in custom Blood maps

[Blackgrowl]

Hey there. No idea if this is the right term, "skybox", I suppose it is, you will see it in the screenshots either way.

Context is, I am playing on Raze 1.8.1, with mods such as...Voxels for Blood, SmoothBlood, Cultists with Correct Guns. However, none of these mods seem to cause any issues with skyboxes but for testing purposes I am also playing without them.
The mod I am playing is called "Hostile Takeover", you may find the link to it here; https://www.moddb.com/games/blood/addon ... keover-v11 (Please note that it is not uploaded by the original uploader, which is Bloatoid, although I believe it's irrelevant here in this context, still some good info)

The map is "hos-e1m9", named "City of Syn".
In RAZE, the Skybox seems to turn from nothing but pitch black into some kind of very wicked mix of wall and terrain textures with a fadeout. Here's a screenshot of it:

In NBlood, the Skybox is a simple pitch black, which is also how I remember it to be since I've played Blood on NBlood first. Here's a picture:

I do not have BuildGDX or DosBOX anymore to test them there.

What could be causing this issue? Is there a way to fix it on my end or I should wait for the next update?

For those curious, this sadly has not been fixed in Raze 1.9.1
