Niagara NDC Access Context

I am using Unreal 5.7 and writing to an NDC from blueprint. The node I am used to using for this has now been marked as “Legacy” and will be “removed”. (WriteToNiagaraDataChannel).

But there is no documentation or examples I can find on the new writer node. The new node uses an “NDC Access Context”, which I do not understand how to create or use.

I cant seem to create an NDC Access Context that compiles and works correctly.

The 5.7 Content Examples still use the legacy node the same way I am.

I cannot find any examples or documentation.

It would be very useful to have a simple working example that illustrates the new API.

Thanks for any help/advice/tips
