Hi Bill,
Any asset that is on the DLS can be included in a route to be uploaded, frankly with or without asking. By uploading it to the DLS the author is agreeing to that – N3V payware routes too I believe!
As has been said, you are not including the actual asset in your upload, merely referencing where you want it placed. The user of your route will still have to download the actual asset separately, though this is largely automatic.
The only question would be about assets from other websites that are not on the DLS. Then permissions may be needed. But again since you are not uploading the actual asset, any user of your route would have to get that asset from the same source you did.
Just for the record, my payware item, ASB Turnout which is not on the DLS already has a disclaimer regarding this. It is.....
‘Route builders may reference ASB Turnout in their work and that work may be published as freeware or payware without reference to me. However, the purchased ASB assets themselves must not be passed on. Any published routes should include details of how and where to obtain the ASB Turnout assets’.
Other payware authors may have other ideas.
So Bill, include anything that’s on the DLS in your route. No problem.
