OR is looking for them only when they are called for. Probably the activity had set spring as season. However if such seasonal folders are not present in the trainset's pack, the author has done it wrong with the .sd files.

I have compared the behavior of MSTS and OR for Loco's with seasonal and weather Textures
With ESD_Alternative_Texture ( 0 ) in *.sd file:
MSTS and OR use the textures in the mains-directory of the Loco

With ESD_Alternative_Texture ( 1 or 252 ) ( snow or season )in the *.sd file:
MSTS use always the textures in the main-directory, also if there are season-Folders present.
If there is a Texture not present in the main-directory MSTS can't find it.

OR is looking only in the corresponding season-folder and/or Weather-folder ( Winter, WinterSnow, Snow )
If OR can't find the texture there it use the default-texture.

I think, this difference is like an additional feature, the Train designer can so, for OR, design as example a train full of snow and ice!

If memory serves me right, someone did this for MSTS a few years ago, adding seasonal winter textures to a set of cars and some locos.. Looked quite good too.

Yes, in the Bernina freeware there is also some trainset with snow and ice around, but it had to be a specific trainset, as MSTS does not handle seasonal textures for trainsets; instead this becomes possible with OR, as Eugen highlights! This could be added into the manual.
