AP Alps PBR Textures

For selected textures that were released for TRS 2019 in build 4.6, they will be gradually replaced by functional seasonal variability. Several textures are now being piloted that work successfully with either new version. For those who will prefer the older version, it is not a problem to undo or change the changes. It is important to announce that all textures will be reworked to 1024 px and will contain several materials for the winter and autumn type. Therefore, this content will be 3x higher than the original.
