Make CustomMeshTriangle warnings

I’m using Make CustomMeshTriangle to procedurally create terrain but it’s giving me these warnings:

Warning  Vertex 0  - the native property is not tagged as BlueprintReadWrite, the pin will be removed in a future release.
Warning  Vertex 1  - the native property is not tagged as BlueprintReadWrite, the pin will be removed in a future release.
Warning  Vertex 2  - the native property is not tagged as BlueprintReadWrite, the pin will be removed in a future release.
Warning  Make CustomMeshTriangle  has no property tagged as BlueprintReadWrite. The node will be removed in a future release.

I’m using 4.6.1.

My OCD is bugging me and I want to get rid of the warnings if possible.

It warning for future updates, as long as you dont update you have nothing to worry about, if you use UE4 original nodes you also dont need to worry about as it should be corrected by Epic in update (at least it should be), if those pins belong to 3rd party plugin then you need to notify developer about it (if he didnt notice that himself already)

They are part of UE4 and not a plugin. So I’m good, updates will fix it automatically?

Well if someone in Epic won’t forget about it ; p so potentailly can break in UE4 update, but as blueprint only user you should not worry about as its problem in UE4 code not yours and Epic should fix it.

Those warnings are actully C++ specific this doc might help you understand them:
