Hi All
To clarify on the licenses for Trainz content (and JointedRail's content), please always check the license tag in the asset. This should be your first stop before making any modifications to an asset.
Most assets will specify what you can/cannot do with the content. For most regions, and creators, screenshots are permitted without obtaining permission (i.e. screenshots are generally not considered redistribution, however some regions may consider it as such). However a creator can specify in the license tag if screenshots are permitted or not. If they are not permitted, then don't do it.
If you wish to obtain permission, then you should contact the creator (or group) directly.
If the license tag is blank, then it generally indicates that no special conditions apply. You MUST still obtain permission before releasing reskins (or unmodified) versions of the content.
If a license tag does state that screenshots of reskins are not permitted, and the creator reports the post to us, we will remove those screenshots. If the license tag does not specify this, then it may be up to the discretion of our moderators.
Regards
