Found out when re-texturing the 308 box that it retains the original look in 1PP, but shows correctly in inventory and surroundings view (TAB). Issue is a View-Pilot LOD which this box model has, other boxes do not and in which there is a selection "camoground" (but not zbytek) which is not referenced in the model.cfg (only zbytek in the model .cfg). Simplest fix would be add named selection "zbytek" to View-Pilot LOD.
