MAZ 5340/5440/6430A8 Reworked

– Reconfigured glass materials, which helped overcome the “overexposure” at the sight glass on the outside with enabled HDR. Once this bug did not notice, because I play without HDR.
– On the advice of Dark_Wolf (for which many thanks to him) corrected some textures, significantly reduce the appearance of polygon mesh at a distance. But completely, unfortunately this was not possible to overcome the bug.
– Several other minor improvements in the model.
