Error Textures with Custom Cubemaps

I’ve been tinkering around with modifying various parts of the maps, but I’ve run into issues with cubemaps and texturing.

When I give a face a texture that was originally nodraw, it shows up as the error texture. I’ve tried buildcubemaps as well as deleting the cubemap textures in the .bsp. I’ve also discovered that if I move a cubemap even one unit away, all attached faces get the error texture.

Attached are pictures of a test section of bm_c1a0a - the first shows the textures as normal, the second shows what happens when I move the env_cubemap entity.

Is this a known issue? Is there a fix for this?


An update: seems like some sort of conflict with the map stored in the vpk. By renaming “bms_maps_dir.vpk” to something else (so the game doesn’t find it), the errors disappear without even needing to recompile.
