What about displacement maps?

[najmm01]

I see no suffix listed for displacement maps.

Also, in the old UE4 wiki, they used "_DP" for this which doesn't conflict with your existing suffixes, so might be a good idea to use the same.

If you're talking about vector displacement maps, I'd recommend _V, whereas for linear displacement maps I'd just go with _H for height.

@LuggLD I guess this makes sense.
@Allar What are your thoughts on this?

I'd cast a vote for _WD for "World Displacement" since it matches the material node well.
