Big fixes to the lighting and another big overhaul of usability is coming in this update, along with several important fixes. Here is the changelog:

LCV4.1.4 Fixes & Improvements

• Big fixes and improvements to design room and photoscene lighting
• Many more fixes to light functionality
• Various improvements to the fixture gizmo
• Added some rollcage parts and exhaust pipes to 3d fixtures
• Implemented optional angle snapping for fixture rotation
• Made clicking nothing when a fixture is selected cause deselection
• Slowed down gizmo scale/move/rotate speeds a bunch
• Fixed "Mod Loading Warning" falsely showing on startup
• Fixed not being able to spawn the same car more than once (3rd time's the charm!)
• Fixed various materials showing incorrectly
• Fixed the gizmo not having different colors in blind mode
• Implemented optimized data handling backend, partly used in campaign hub

Still plenty on our list, but we do hope the rather broken feeling 4.1.3 is well behind us with 4.1.4.
Cheers!
