Can't transform VFM Sky due to brush imported
Describe the bug The map brush and the 3d sky brush are the same when imported, causing that if you pick the sky and transform it, your map brush will be displaced and upscaled.
To Reproduce Steps to reproduce the behavior:
- Import a map
- Pick the entire 3D sky and use the "Transform 3d VMF sky" option from "Object"
- See error
Expected behavior The map brush should be separated from the sky brush so when you transform the sky you get the map right

This will probably be quite difficult to fix, since it would require automatic detection of the solids that are part of the 3d sky (and at that point, might as well do the transformation automatically too). For a workaround you can disable solid merging when importing, though this will make the import slower.
The default settings of the latest version do not have this issue, since solid merging is disabled.
